La Union

History

Early history

During its early history, the province was inhabited by various ethnolinguistic groups, including the Ilocanos, Pangasinenses, and Cordillerans (Igorots), who actively engaged in trading and bartering while practicing animistic and polytheistic indigenous religions and traditions.

In the northern section, early settlements were established along the coastal plains of Purao (now Balaoan), Darigayos, and the areas surrounding the Amburayan River. These settlements were primarily inhabited by the Samtoy (Ilocanos). Historian William Henry Scott documented that Balaoan was historically referred to as being "rich in gold" due to its proximity to the gold mines in the Cordillera region. The town served as an emporium for the exchange of Igorot gold through barter and trade among lowlanders, highlanders, and foreign merchants in Tagudin. Similarly, Baratao (now Bauang) has been identified by historians as a settlement of comparable importance to Purao as emporium of gold mines.

In the southern section, the areas of Agoo and Aringuey (now Aringay) were early settlements of the Pangasinenses. Agoo functioned as a trading port with Sual as its only rival. Agoo was frequented by Japanese and Chinese ships, whose merchants engaged in commerce or bartered gold with natives. Aringuey served as a coastal maritime trading hub and the terminus of the Aringay-Tonglo-Balatok gold trail, located along the delta of the Aringay (Ifugao) River. This route facilitated the transport of gold from the Ibaloi villages of Acupan and Balatok in the southern areas of present-day Benguet to the trading centers of Aringay, with further distribution to the port settlement of Agoo.

These trading activities were part of a larger maritime exchange network that extended across the Indian Ocean and the South China Sea. Products exchanged within this network included porcelain, silk, cotton, beeswax, gems, beads, and precious minerals, with gold being a significant commodity. Artifacts like porcelain and pottery, uncovered during the renovation of the Catholic church in Agoo and now housed in the Museo de Iloko, testify to this trade activity.

Spanish Colonial Era

A year after Miguel Lopez de Legazpi made Manila the capital of the Philippines on 24 June 1571, the Spaniards launched expeditions to Northern Luzon "to pacify the people in it".

In June 1572, Spanish explorers led by conquistador Juan de Salcedo, the grandson of Miguel López de Legazpi, launched an expedition northward and founded several Spanish settlements, including those in the Ilocos region and the city of Vigan.

By 1575, Salcedo navigated the Angalacan River to the Lingayen Gulf in pursuit of Limahong, a Chinese pirate who had fled to Pangasinan after his fleet was driven away from Manila in 1574. There, they encountered and attacked three Japanese ships, mistakenly identifying them as part of Limahong’s fleet.

After the ships retreated, Salcedo pursued them and arrived at a Japanese port in Agoo. The Japanese mercenaries and local natives were subjugated and required to pay tribute to the Spanish Crown. Although some initially resisted, those who complied were allowed to remain. This encounter earned Agoo the title "El Puerto de Japón" (Japanese Port) from Miguel de Loarca in 1582, as it had long served as a hub for trade among Japanese and Chinese merchants and local natives.

Salcedo continued his expedition northward and arrived at what is now San Fernando. When he demanded tribute from the natives, they sought permission to ascend the mountains to gather their offerings but failed to return. Salcedo then proceeded to Atuley (modern-day San Juan) and further north until they encountered a large Ilocano settlement called "Purao," referring to the gleaming white sands of its beaches along the South China Sea.When the natives of Purao refused to pay tribute, it led to the first recorded conflict in the Ilocos region, known as the Battle of Purao. This encounter resulted in the shedding of the first Ilocano blood in defiance of foreign rule. The river "Purao" was later renamed "Darigayos," derived from the Iloco words "dara" (blood) and "ayos" (flowed), meaning "where blood flowed." Continuing his journey, Salcedo arrived at Bigan (now Vigan), a settlement of Chinese traders, and formally established it as Villa Fernandina de Vigan in honor of Prince Ferdinand, the son of King Philip II of Spain.

By the 17th century, the Spanish had established settlements, or pueblos, organized into sitios and rancherias, in Igorot land in La Union. These were governed by a gobernadorcillo, alcalde-mayor and cabeza de barangay, with many of these settlements established by Augustinian friars during the 16th century's expansion phase.

Philippine Revolution

The Philippine Revolution began in 1896, but La Union initially saw limited revolutionary activity. On 15 November 1896, the newspaper La Campaña de Filipinas reported that the provinces of Ilocos and La Union were "not up in arms" but showed "sympathy for the uprising." Despite this initial passivity, the province eventually joined the struggle against Spanish colonial rule. In response, Spanish authorities enacted severe reprisals, including torture and false accusations, often targeting local elites, clergy, and suspected rebels.In 1896, three native coadjutor priests from La Union, Padre Adriano Garces of Balaoan, Padre Mariano Gaerlan of San Fernando, and Padre Mariano Dacanay of Bacnotan, were arrested and charged with masterminding a "supposed conspiracy" in La Union. They were brutally tortured by friars and the Guardia Civil in Vigan, enduring inhumane treatment that left lifelong scars on survivors like Padre Dacanay.

In Balaoan, a secret revolutionary group formed by seven prominent citizens namely; Luciano Resurreccion, Proceso Ostrea, Antonio Ostrea, Rufino Zambrano, Fernando Ostrea, Patricio Lopez, and Julian Peralta—sought to revolt against the tyranny of the Guardia Civil and Cora Parrocos. The group was betrayed by Captain Juan of Agoo to the friars. They were arrested, and without trial, executed by firing squad at the town cemetery. Only one of the men survived, having been wounded in the leg. In their honor, a Masonic lodge named Siete Martires was established.

In Agoo, around 60 suspected subversives were executed by the Guardia Civil and their bodies later interred in a corner of the town plaza. In nearby Aringay, 96 citizens were shot without trial by Spanish forces. A monument was later erected in the plaza to honor these patriots. On 10 September 1896, Spanish authorities, led by Friar Rafael Redondo, arrested Dr. Lucino Almeida, the highest-ranking native official in La Union, along with other suspected revolutionaries. They were accused of involvement in a fabricated conspiracy to assassinate Spanish officials, based on a false confession from a telegrapher. Almeida and 20 other prominent natives were exiled to Balabac Island, Palawan.

Despite these events, La Union was hailed as "una provincia modelo" (a model province) in 1897 by the pro-government El Comercio for its contributions to Spain's defense. However, in 1898, the relative tranquility of La Union was shattered when an uprising and massacre in Santo Tomas ignited widespread agitation.

American Colonial Era

After the Philippine-American War, La Union, like much of the country, faced widespread chaos. La Union revolutionary leaders such as Capt. Aniceto Angeles, Francisco Peralta, and Col. Juan M. Gutierrez were executed through public hanging and firing squad in Bangar and San Fernando town plaza, underscoring the conflict’s harsh aftermath.

From 1899 to 1901, La Union was under military rule, with Colonel William Penn Duvall administering both the province and Benguet beginning on 18 March 1900. During this time, both the elites (babakanang) and townspeople (cailianes) endured forced relocations, extrajudicial killings, sexual assaults and significant property damage. This period of military governance, however, was short-lived.

In 1901, La Union transitioned to civilian governance, signaling the start of a more organized and democratic system inspired by American models. The transition marked a shift from the "spiritualism" enforced by the Catholic friars under Spanish rule to a secular system.

Despite this shift, U.S. military leaders, including Colonel Duvall, resisted relinquishing power and frequently clashed with the Philippine Commission, led by Civil Governor William Howard Taft. The conflict escalated to U.S. Secretary of War Elihu Root, who intervened to ensure La Union’s formal adoption of civilian governance on 15 August 1901.

Don Joaquin Vicente Eulogio J. Ortega became La Union's first civilian governor, ushering in a new era of governance. However, key positions, such as the provincial treasurer, remained under American control. The colonial administration also prioritized education, suffrage, civil rights, and political participation, thus empowering Filipinos to engage in the democratic process.

Introducing the Thomasites—American teachers tasked with promoting "Americanization." English became the primary medium of instruction, aiming to instill American ideals. A notable example of this initiative’s success is Camilo Osias, a student from Balaoan, who pursued studies in the U.S. and later emerged as a respected educator and public servant. By 1902, La Union's education system had grown to include 89 schools spread across various pueblos (towns). A total of 8,917 pupils were enrolled—5,652 boys and 3,265 girls—constituting 15% of the province's population. Schools were established in key towns like San Fernando, Bangar, Rosario, Aringay, Cava, Agoo, Balaoan and Namacpacan (Luna), with some operating in repurposed Spanish-era convents.

Japanese Occupation

The Japanese invasion of La Union during World War II was a pivotal moment in the province's history, given its strategic importance to both Allied and Japanese forces. In 8 December 1941, Japan launched an attack on U.S. military installations including the Camp Wallace and residential areas in the province, following the attack on Pearl Harbor.

By 11 December, the Japanese forces had successfully captured Vigan and dispatched additional troops to seize Laoag and its airfield. As American forces retreated, Lieutenan Gen. Masaharu Homma left a small garrison in Vigan and redirected the main forces to support operations at Lingayen Gulf.

By 20 December, the combined forces of the Col. Kanno and Gen. Shizuichi Tanaka Detachments advanced south along Route 3. By 21 December 1941, Japanese forces had occupied Bacnotan following the successful overcoming of Philippine defenses in the area. On 22 December, they advanced to San Fernando further consolidating their position. Japanese troops also landed in Agoo and swiftly established control over the town by early 1942. Despite these rapid advances, Filipino and American forces continued to resist the Japanese occupation, contributing to the broader efforts of the Allied campaign in the Philippines.

Battle of Rosario (Invasion of Lingayen Gulf)

On 22 December 1941, the Japanese 4th Tank Regiment and the 47th Infantry Regiment under the command of Col. Isamu Yanagi, supported by a massive flotilla of navy ships tried to land in Agoo to make it one of three major beachheads for the Japanese Invasion of Lingayen Gulf, although weather dispersed their forces and made them deploy on a wide stretch of beach that ranged from Poro Point (San Fernando) to as far south as Damortis. These forces later met the commonwealth defence forces—consisting of the 26th Cavalry Regiment (Philippine Scouts), the Philippine 21st Division, the Philippine 11th Division, and the newly formed Philippine 71st Division—in what would later be called the Battle of Rosario.

During the Japanese occupation in the province, La Union was governed by Gov. Jorge Camacho (1941–1942), Gov. Bonifacio Tadiar (1942–1944), and Gov. Bernardo Gapuz (1945) under the administration of President José P. Laurel's Japanese-sponsored "puppet" government. The province endured strict military controls, forced labor, food shortages, and widespread violence including extrajudicial killings and sexual violence. Despite these conditions, resistance movements emerged, with many residents engaging in guerrilla warfare against Japanese forces. Guerrilla camps was established all over the province including Camp Spencer in Darigayos, Luna and Camp 121 and Barrio San Cristobal in Bangar.

Post-war Era

The postwar recovery period marked a return of the tobacco industry to the Ilocos Region. Ever since the end of the tobacco monopoly, tobacco production had declined in the Ilocos as Filipinos started shifting from locally made cigars to foreign made cigarettes. But after reading a feature article series by Maximo Soliven which explained why Virginia tobacco would grow well on Ilocos soil, businessman Harry Stonehill was convinced to invest extensively in rebuilding the industry. He established the Philippine Tobacco Flue-Curing and Redrying Corporation (PTFCRC) in 1951 and recruited farmers throughout Region 1 to produce tobacco. The following year, La Union Congressman Manuel T. Cases filed a bill to "limit the importation of foreign leaf tobacco," which was eventually signed by President Elpidio Quirino as Republic Act No. 698. This allowed Stonehill's investments to make a handsome profit, and the newly-rebuilt local industry to bloom. While Stonehill was later deported in the 1960s for tax evasion and bribery of government officials in what would later be called the Stonehill scandal, the tobacco industry continued to grow.

Martial law era

Although economically affected by the rapid peso devaluation brought about by unbridled election spending heading into the 1969 presidential elections, political life in La Union was not significantly impacted by Ferdinand Marcos’ declaration of Martial Law in 1972.

The powerful family factions which had dominated La Union politics since before the American colonial era largely remained in place, although the family of Congressman Jose D. Aspiras became much more prominent after he became Marcos’ Tourism Minister. The main political change was the increased power of regional and provincial offices of national agencies, whose directors were answerable directly to Marcos.

This technique used by Marcos to consolidate political power did not get much resistance in the Ilocos Region, including La Union, which had strong ethnic associations with the Marcos family. The Marcos administration's use of violent methods for stifling dissent thus mostly took place in other, non-Ilocano provinces, such as nearby Abra, Kalinga, and Mountain Province. Long-time second district congressman Manuel T. Cases had formed an alliance with Marcos along with the other strongman congressmen of the Ilocos Region, and his successor Jose D. Aspiras was also a close associate of Marcos who was made Minister of Tourism after Martial Law was declared.

But there were still La Union natives who were willing to object to the authoritarian practices and abuses of the Marcos administration, despite personal risk. This included San-Fernando-raised student activists Romulo and Armando Palabay, UP Students and La Union National High School alumni who were imprisoned for their protest activities, tortured at Camp Olivas in Pampanga, and later separately killed before the end of Martial Law. Romulo (age 22) and Armando (age 21) were posthumously honored when their names were etched on the Wall of Remembrance at the Philippines' Bantayog ng mga Bayani, which honors the heroes and martyrs who fought the authoritarian regime.

Agoo, La Union, native Antonio L. Mabutas had become Archbishop of Davao by the time of Martial Law, and spoke actively against the human rights abuses of that time, particularly the torture and killings of church workers. The pastoral letter he wrote against Martial law, "Reign of Terror in the Countryside," is notable for having been the first pastoral to be written against Marcos' martial law administration, and even doubly notable because Mabutas was considered a conservative within the Catholic church hierarchy in the Philippines.

Contemporary

La Union was severely hit by the 1990 Luzon earthquake. Five municipalities in La Union were affected: Agoo, Aringay, Caba, Santo Tomas, and Tubao with a combined population of 132,208. Many buildings, including the Agoo Municipal hall, the Museo de Iloko, the parish church of Aringay, and the Basilica Minore of our Lady of Charity, collapsed or were severely damaged. 100,000 families were displaced when two coastal villages sank due to liquefaction. The province suffered many casualties leaving 32 people dead.

From the mid-2000s to the early 2010s, an influx of entrepreneurs began putting up establishments such as boho-chic-style art hostels and third-wave coffeeshops in San Juan and Agoo. They were initially attracted to the already-established surfing scene of Barangay Urbiztondo in San Juan, but eventually envisioned business in the province as an alternative to the stresses of city-based employment. This coincided with the phase-by-phase opening of the Tarlac–Pangasinan–La Union Expressway (TPLEX), which made La Union more accessible to tourists from Metro Manila.

Alongside the rising influence of social media outlets Twitter and Instagram, these factors led to a drastic tourism boom that made San Juan—previously been seen as just one of the Philippines' many surfing venues—a major backpacker's destination whose attractions centered on surfing and art.

San Juan began to be featured prominently in independent films such as Jay Abello's 2015 film Flotsam and JP Habac's 2017 film I'm Drunk, I Love You, and the province began to be referred to by the colloquial initialism "ElYu."

Among Philippines literary circles, the town of Bauang has also become a pilgrimage site of sorts for celebrating the life of and works of writer and World War II martyr Manuel Arguilla, with writers visiting the author's hometown to experience the landscapes that inspired him, and which featured prominently in his stories. The most prominent event celebrating Arguilla was the 2017 run of the Taboan Literary Festival, a celebration of Philippine literature which changes venues every year, organized by the National Commission on Culture and the Arts during every National Arts Month in February. Among the prominent artists who spoke about Arguilla at the festival were writer-academic Butch Dalisay and National Artist of the Philippines for literature Bienvenido Lumbera.

Geography

La Union, located in the southwestern part of the Ilocos Region, is bordered to the north and northeast by Ilocos Sur, to the south by Pangasinan, to the east by Benguet, and to the west by the Lingayen Gulf and South China Sea. Geographically, it lies 273 kilometers (170 mi) north of Metro Manila and 57 kilometers (35 mi) northwest of Baguio City.

Among the provinces in the Ilocos Region, La Union is the smallest in terms of land area, covering 149,309 hectares, which constitutes 11.60% of the region's total land area and about 0.5% of the entire country. The province is divided into two districts. District I, comprising 70,069 hectares (46.93% of the province's land area), includes San Gabriel, the largest municipality, with 15,500 hectares, followed by the City of San Fernando with 10,688 hectares, while Luna is the smallest. District II covers 79,240 hectares (53.07% of the province), with Bagulin having the largest area, followed by Aringay, while Santo Tomas occupies the least space.

Topography

La Union’s topography is predominantly hilly, gradually rising eastward from its coastal plains. The province’s physiography can be classified into four primary surface configurations: coastal plains, coastal hills, broad interior valleys, and mountain ridges with narrow valleys. These landforms have been shaped by coral alluvium (sand and clay) deposited by flowing water.

The coastal plains of La Union are narrowest near Damortis and Santo Tomas, and widest near Balaoan, extending up to 15 kilometers (9.3 mi) inland. Along the South China Sea, the coastal plains transition sharply to steep ranges, with elevated areas in Santo Tomas, Agoo, Bauang, and Balaoan, and gentler slopes in Bacnotan, San Fernando, and San Juan.

These towns also features mangrove swamps, and the soils in this area are sandy and saline, particularly in southern San Fernando and surrounding areas. Coastal hills in La Union rarely exceed 300 kilometers (190 mi) in elevation, merging with the Cordillera mountain ranges to form narrow valleys. The soils in these areas are primarily heavy loam and clay, which are common in Agoo, Aringay, Santo Tomas, and Rosario, while northern San Fernando is characterized by gravelly, eroded loam.

The eastern frontier of the province is predominantly mountainous, dominated by the Gran Cordillera mountain ranges, specifically the Central and Northern Cordillera, which run parallel to the South China Sea coast. The highest peak in the province is located in Bagulin, at an elevation of 1,200 feet, with other elevated areas found in San Gabriel and Burgos. The fertile, fan-shaped interior valleys in San Juan, San Fernando, and Balaoan, formed by river delta sediments, are crucial for agriculture, though they are prone to flooding during heavy rainfall.

Salty-loam and alluvial soils, which are ideal for crops such as rice and tobacco, are prevalent in Naguilian, Aringay, Bauang, Balaoan, and Luna. The eastern mountain ranges, characterized by steep slopes and narrow valleys, are covered with reddish, clayish soils, particularly in Bacnotan, Agoo, San Fernando, San Juan, and Bauang, which are not suitable for agricultural use.

La Union is home to nine valleys—four in the northern part of the province (Bangar, Balaoan, Bacnotan, San Juan) and five in the south (Tubao, Aringay, Santo Tomas, Rosario, Naguilian)—which support agricultural land. These valleys are crossed by narrow, turbulent rivers. Further to the east, elevated plateaus and peaks that rise dramatically.

Climate

According to Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), La Union experiences a 1st Climatic Type of the Köppen Climate Classification, which is characterized by two distinct seasons: a dry season from November to April and a wet season from May to October. The Southwest Monsoon (SWM) brings heavy rainfall during the wet season, while the Northeast Monsoon (NEM) causes relatively dry conditions as it passes over the Cordillera Mountains. Rainfall is not evenly distributed throughout the year, with the peak rainfall occurring from July to September.

La Union is also affected by tropical cyclones, with 85 such weather systems recorded between 1948 and 2009, including one super typhoon. These storms, which occur most frequently from July to October, have adverse effects on tourism, agriculture, and infrastructure. During strong typhoons, businesses often close, power outages are common, transportation becomes limited, and crops suffer damage, reducing agricultural production.

Administrative Divisions

La Union comprises 19 municipalities and 1 component city, all of which are organized into two legislative districts. The First Congressional District consists of 8 municipalities and 1 city, while the Second Congressional District consists of 11 municipalities.

Barangays

La Union consists of 576 barangays, which are spread across its 19 municipalities and 1 city. According to the 2020 census, the barangay with the highest population is Sevilla, located in the City of San Fernando, boasting a population of 11,316. When cities are not taken into account, Central East (Poblacion) in the municipality of Bauang ranks as the most populous barangay, with 4,249 residents. In contrast, Caggao in Bangar has the smallest population, totaling just 192 inhabitants.

Conservation

Protected areas

The Philippines' National Integrated Protected Areas System identifies three protected areas in the province of La Union. These are:

The Agoo-Damortis Protected Landscape and Seascape (10,774.68 hectares) located across the municipalities of Agoo, Sto. Tomas, and Rosario;

The Naguilian Watershed Forest Reserve (90 hectares) in Naguilian; and

the Marcos Highway Watershed Forest Reserve (15,038 hectares) located in across the municipalities of Agoo, Tubao, Rosario, Pugo, Santo Tomas, and Aringay.

Numerous other protected areas have been established locally through various municipal ordinances, among the more notable of which are the Bauang-Bakawan Eco-Tourism Park in Bauang, the Urbiztondo Fish Sanctuary in San Juan, La Union, the Aringay Marine Protected Area in Aringay, La Union, and the Dalumpinas Oeste Pawikan Conservation Center in San Fernando, La Union.

Endangered and vulnerable species and conservation efforts

La Union is well known for being a preferred birthing ground of three species of Sea Turtles, locally known as "Pawikan": the Green sea turtle; the critically endangered Hawksbill sea turtle; and the Olive Ridley sea turtle which is classified as vulnerable. In 2011, the local government head of Barangay Dalumpinas Oeste in San Fernando, La Union spearheaded a Conservation Program to protect the increasing number of Turtle nests found on their coast.

La Union's varied geography serves as home to a wide range of bird species, among the largest of which are the Brahminy kite, and Philippine serpent eagle. Among the endangered bird species who stay in the province are the Java sparrow.

Endangered tree species which have been identified in La Union include the Molave (Vitex parviflora) while vulnerable species include the Dau (Dracontomelon dao) and “Pammittaogen” (Calophyllum pentapetalum).

Demographics

Population

According to the 2020 census conducted by the Philippine Census of Population and Housing, La Union had a population of 822,352, with a population density of 550 people per square kilometer (1,400 per square mile). This is an increase of 35,699 persons over the total population of 786,653 persons in 2015 Census of Population. The household population was nearly evenly distributed, with 50.6% male (414,860) and 49.4% female (405,480).

San Fernando is the most populous area in La Union, with 125,640 residents (15.28% of the province's total population), followed by Bauang (78,449), Agoo (66,028), Rosario (60,278), and Naguilian (52,189). Conversely, Burgos is the least populous municipality with 9,006 residents, followed by Santol (14,166), Bagulin (14,428), Sudipen (17,187), and San Gabriel (18,943).

Santol recorded the fastest population growth between 2015 and 2020, with an annual rate of 2.71%, followed by Burgos (2.34%), Tubao (2.13%), San Juan (1.81%), and Rosario (1.77%). In terms of population density, Agoo was the most densely populated municipality, with 1,250 persons per square kilometer, while Burgos had the lowest density at 127 persons per square kilometer.

Age distribution reveals that 26.3% of the population were young dependents (under 15 years), 66.1% were of working age (15–64 years), and 7.6% were elderly (65 years and older). Males slightly outnumbered females in younger age groups, while females were more numerous among the elderly, reflecting higher life expectancy for women. The overall sex ratio was 102 males per 100 females, with variations across age groups: 108 males per 100 females among those under 15, 105 in the working-age population, and 70 among the elderly.

The median age in La Union was 28.5 years. Senior citizens (60 years and older) comprised 11.5% of the population, 56.4% of whom were women. As of 2012, La Union had the longest life expectancy in the Philippines at 78.3 years.

Religion

According to the 2020 census on religious affiliation in the Ilocos Region, the majority of La Union's household population identifies as Christian, with Roman Catholics comprising 69.5% (695,867 individuals). Iglesia ni Cristo represents a significant minority with 23,374 members, while Islam accounts for 0.19% of the population (1,932 adherents). Buddhism, though present in smaller numbers, constitutes 0.25% or 163 of the population.

In addition to Roman Catholicism and Iglesia ni Cristo, the province is home to a range of Christian denominations, including Protestantism, the Philippine Independent Church (Aglipayan), Jehovah’s Witnesses, the Pentecostal Church of God Asia Mission, Bible Baptist Church, The Church of Jesus Christ of Latter-day Saints, and the Church of Christ, among others. Non-Christian religions such as Taoism and Hinduism are also practiced by a small portion of the population, reflecting the province’s cultural diversity and historical influences from trade and migration.

Ethnicity

Historically, La Union has been home to several ethnolinguistic groups, including the Ilocanos, Pangasinan, and Cordillerans (Igorot). The Cordillerans primarily consist of the Ibaloi, Kankanaey, and the Bago, also known as Bago-Igorot. The Bago are a highland indigenous people referred to as new Christian converts during Spanish colonization in the province.

Ethnically, La Union is predominantly Ilocano, according to a 2020 report by the Philippine Statistics Authority. The Ilocano ethnic group accounts for 673,312 or 81.88% of the population. In the southwestern part of the province, there are 10,319 Pangasinan people. Indigenous communities, including the Kankanaey (42,552), Bago (24,757), and Ibaloi (9,107), reside in the municipalities of Sudipen, Santol, San Gabriel, Bacnotan, Tubao, Pugo, Bagulin, and Burgos.In Bagulin alone, 85% of the population, or 11,539 individuals, belong to indigenous groups. In Pugo, the majority of indigenous residents are from the Bago people. These communities have faced displacement, such as the eviction from the Mount Shontoug area in Pugo during the construction of the Marcos bust. Southern La Union, particularly Agoo, Santo Tomas, and Rosario, was historically ethnically Pangasinan; by the 16th century, migration from northern La Union and Ilocos, as recorded by Fray Andrés Carro in 1792, resulted in the area becoming predominantly Ilocano-inhabited and ethnically Ilocanized Pangasinenses.

Other ethnic groups in La Union include 23,518 Tagalog people and 10,025 Bisaya or Binisaya people, 4,043 Bicolano people, 2,410 Kapampangan people, 2,383 Hiligaynon (Ilonggo) people, 2,311 Ifugao people, 1,717 Itneg (Tingguian) people, 1,586 Waray people, 1,319 Cebuano, 1,181 Maranao, people as well as foreign nationals such as 473 Chinese, 410 Indian, and 142 American, contributing to the province's cultural diversity.

Language

Iloco, or Iloko, is the primary language spoken in La Union, with the Abagatan (Southern) dialect as its regional variation. In 2012, Iloco was officially recognized as the language of La Union through Provincial Ordinance No. 026-2012, known as the Iloco Code. Pangasinan is also spoken in the southern part of the province, particularly near the border with Pangasinan. Meanwhile, Kankanaey and Ibaloi are spoken by the Cordilleran communities residing in the highland areas of La Union.

Historically, in 1884, Governor Federico Francia issued an espediente (report) on the dialectos que hablan (dialects spoken) in La Union. The report noted that most umilis (townspeople) spoke Ilocano and Pangasinan, with Santo Tomas and Rosario being the only towns where both languages were spoken due to their proximity to Pangasinan. The remaining 11 towns predominantly spoke Iloco, excluding the scattered Igorrotes communities in rancherías. Up to the end of Hispanic rule, Ilocano remained the predominant lingua franca of La Union.

Economy

La Union’s economy is driven by three primary sectors: agriculture, industry, and services. The service sector plays a dominant role, comprising 81.28% of all business establishments, while industry contributes 17.21% and agriculture makes up 1.51%. In 2022, La Union emerged as the second fastest-growing economy in the Ilocos Region, with a growth rate of 7.7%.

According to preliminary estimates from the 2019 Provincial Human Development Index by the Philippine Statistics Authority (PSA), La Union scored 0.76, indicating a high level of development and rank as top 9 in the Philippines. The province’s Gross Domestic Product (GDP) in 2022 was valued at ₱118.60 billion, representing an 18.1% share of the region’s total economy.

La Union ranked second in terms of per capita GDP, which was recorded at ₱140,840 and ₱124,580 over two different measures. However, the 2021 data from the PSA showed an increase in poverty incidence, with 13.90% of the population and 10.70% of families living below the poverty line, up from 5.20% and 3.70% in 2018, respectively.

Agriculture

Crop Production

Agriculture, particularly crop production, remains vital to La Union's economy and its city and municipalities. Major crops include rice (palay), corn, tobacco, sugarcane, root crops, legumes, fruits, and a variety of lowland and highland vegetables.

In 2024, the province recorded a palay production of 127,825 metric tons, equivalent to a 137% rice sufficiency level. This figure was lower than the 173,891.55 metric tons produced in 2023, which represented a 1.53% increase from the 171,276.53 metric tons recorded in 2022.
