Culion, officially the Municipality of Culion (Tagalog: Bayan ng Culion), is a municipality in the province of Palawan, Philippines. According to the 2020 census, it has a population of 23,213 people.[5]
Key Information
Culion consists primarily of Culion Island as well as 41 minor surrounding islands, as part of the Calamian group of islands.[6]
It was a former leprosarium, starting in 1906 under the American colonial regime until the American commonwealth of the Philippines era. Although leprosy on the island-town was abolished in the 1980s, it was only in 2006 when it was declared a leprosy-free area by the World Health Organization.[7][8] The municipality was created by virtue of Republic Act No. 7193 on February 19, 1992.[9] In May 2017, the Philippine National Commission for UNESCO began its initiative to prepare the dossier of Culion's leprosy documentary heritage, which will be nominated in the future in the UNESCO Memory of the World Programme.[10] In May 2018, the Culion Museum and Archives was officially nominated by the Philippines in the UNESCO Memory of the World Register – Asia and the Pacific.[11] On June 18, 2018, Culion Leprosy Archives was officially inscribed in the Memory of the World Register – Asia and the Pacific. The government and the Asia-Pacific bloc aims to nominate the archives further to the International Memory of the World Register. If approved by UNESCO, it will be the fifth internationally recognized documentary heritage of the Philippines, increasing Culion town's feasibility to become a World Heritage Site in the future.[12]
History
[edit]Spanish colonial period
[edit]Aside from churches, the Spaniards built defensive fortifications in strategic places like Taytay, Cuyo, Agutaya, Linapacan, including a watchtower and fort in the locality of Libis.
In 1858, Spanish Palawan and the Calamianes were partitioned into two provinces, Castilla and Asturias. Castilla, which included northern Palawan, retained its capital in Taytay. Asturias extended south to Balabac. In 1873, the capital of Palawan was changed from Taytay to Cuyo. The French anthropologist Antoine-Alfred Marche traveled the Philippines and documented his research of many places. French Ambassador Pierre Revol in particular translated Marche's account of the Calamianes and Culion.
Marche refers to Culion as the principal village of the Calamianes. The fact that a boat from Manila "touches Culion once a month" attests to the growing economy of the place at that time. Marche's description of the place and people he met in the 1880s have been important indicators of the ethnography of Calamianes for more than a hundred years.
Claudio Sandoval y Rodríguez, a Justice of the Peace, resided and held office in Culion, supporting the primacy of Culion as a leading settlement of the Calamianes. Sandoval, a Spanish mestizo from Jaro, Iloilo, married Evarista Manlavi, the daughter of a rich landowner from Cuyo. Sandoval became the Juzgado de Paz de Culión, Calamianes and held office sometime in the late 1880s. The seal of Claudio's office was found stamped on a handwritten circular dated December 11, 1889 that he sent to all residents within Culion's "roriedad y sus visitas," warning them of the penalties to be imposed on them if caught gambling. Culion's "visitas" included the island of Busuanga and other areas in Calamianes.
A remnant of the fort in San Pedro located somewhere in Burabud testifies to the rich history of Culion. In the early 1990s, it was widely believed that the roots of balete trees had already invaded this fort. The fort was built by Spanish Augustinian Recollects and is older than the one in Culion proper, the Immaculate Conception Church built by the Jesuits. This fort in San Pedro was more or less built in the same time span as the forts in Agutaya, Taytay and Cuyo which all still stand today and are preserved by the government of Palawan.
American commonwealth and Culion as a leprosarium
[edit]
When the Treaty of Paris was signed on December 10, 1898, wherein Spain sold the Philippines to the United States for 20 million dollars, the funding of Culion as a reservation was closely related to the Americans' early efforts to establish a form of public health policy in the Philippines as part of their long-term intentions to occupy the archipelago.
One of the motivating factors for the creation of the Manila Board of Health was traditional belief that the maintenance of public health required the isolation of cases of leprosy from the rest of the public. After an investigation of a number of sites, the island of Culion was selected as a segregation colony in 1901. On October 27, 1902, the Second Philippine Commission appropriated an initial amount of $50,000 for the establishment of Culion under the Secretary of Interior Dean C. Worcester and Director of Health Victor G. Heiser.[13] On August 22, 1904, Luke E. Wright, the American Civil Governor of the Government of the Philippine Islands, signed Executive Order No. 35 which transferred the jurisdiction and control of Culion from the Municipality of Coron, reserving the same as a leper colony and a government stock farm.
Timeline
[edit]- On May 27, 1906, the first contingent of 370 patients from Cebu was brought to Culion by two Coast Guard cutters, the Polillo and the Mindanao.
- On September 12, 1907, Act 1711 of the Philippine Commission was passed, giving full responsibility to the Director of Health for the compulsory segregation of the lepers, and confinement and treatment in Culion.
- Between 1906 and 1910 the Americans rounded up 5,303 leprosy afflicted individuals and brought them to the colony. On July 18, 1912, acting Governor General Newton Gilbert signed EO No. 35, further defining the territory of the leper colony and government stock farm.
- In 1913, a special coinage issue was minted in aluminum by a private firm for the inmates of the Colony. Further special coinage issues would be minted for them at the Manila Mint from 1920 to 1930. A special paper money issue was generated during World War II for their use as well.
- In 1917, Section 1066 of Act No. 2711 (Revised Administrative Act) provided that the Department Head through the Director of Health shall have jurisdiction over the colony and its waters for the efficient management of the sanitarium.
- On June 18, 1952, Congress passed R.A. No. 753 which transferred administrative control to the Director of Hospitals. In 1964, the Secretary of Health again took administrative control and enforcement of rules and regulations over all the lands and waters of Culion Leper Colony as provided under Section 106 of the Revised Administrative Code. Sections 1060 to 1071 of RA no. 753 was later repealed by Republic Act No. 4073, an Act further liberalizing the Treatment of Leprosy by Amending and Repealing Certain Sections of the Revised Administrative Code, resulting in the loss of jurisdiction by the Department of Health over the natural resources of Culion.
- In 1979, a Culion Committee was created under Letter of Instructions No. 796. The Ministry of Human Settlements conceived and organized in 1982 an alternative development approach for residents of Culion under the Culion Development Project (CDP). This was later amended by Executive Order No. 241 on July 24, 1987, that transferred the said committee and the CDP to the Palawan Integrated Area Development Project (PIADP) of the National Council on Integrated Area Development (NACIAD). This transfer did not however affect the jurisdiction of DOH over the Culion Leper Colony.
- On June 22, 1988, Congress passed R.A. No. 6659 that authorized qualified residents of Culion Leper Colony to vote for the elective provincial officials of the Province of Palawan. In 1991, Speaker Ramon Mitra and House Representative David Ponce De Leon introduced a house bill for the creation of the Municipality of Culion. On February 12, 1992, President Corazon C. Aquino signed Republic Act 7193 creating the Municipality of Culion in the Province of Palawan.[9]
- May 8, 1995 was when the first election of municipal and barangay officials of Culion was held resulting in the election of Mr. Hilarion M. Guia and Mr. Emiliano Marasigan Jr. as its first duly elected Mayor and Vice Mayor, respectively.
- On October 29, 1998, through Department of Health Administrative Order No. 20-A Series of 1998, administrative control and authority over the Municipality of Culion was officially transferred from the Department of Health to the Municipality ending nearly one century of administrative control by the health department over Culion Island.

- On March 12, 2001, Republic Act 9032 signed by President Gloria Macapacal Arroyo expanded the area of jurisdiction of the Municipality of Culion, Province of Palawan, amending for the purpose Republic Act 7193. The barangays of Balala, Baldat, Binudac, Culango, Galoc, Jardin, Libis, Luac, Malaking Patag, Osmeña and Tiza were declared legally existent upon the creation of the Municipality of Busuanga to the Municipality of Culion. Barangays Burabod and Halsey were transferred from the Municipality of Busuanga to the Municipality of Culion subject to ratification by plebiscite in the two municipalities of Culion and Busuanga. Barangay Carabao for the Tagbanua indigenous cultural community was likewise created subject to ratification by plebiscite in Culion.
- On July 15, 2002, plebiscites held in Culion and Busuanga simultaneously with the election of barangay officials and Sangguniang Kabataan representatives resulted in the ratification of the transfer of Halsey and Burabod to Culion and the creation of Barangay Carabao.
- In May 2018, the Philippines nominated the Culion Museum and Archives to the Memory of the World Register – Asia and the Pacific. The archive's declaration of passage or failure will be announced soon.[11]
- On June 18, 2018, the Culion Leprosy Archives was officially inscribed to the Memory of the World Register – Asia and the Pacific.[12]
Geography
[edit]
Culion is an island situated at the northernmost part of Palawan. It is part of the Calamian Archipelago in northern Palawan that also includes the municipalities of Busuanga, Coron, and Linapacan. During the Spanish Period, these were known as Las Islas de Calamianes, Provincia de España.
The municipality has a land area of 500 square kilometres (190 sq mi) which includes the 41 surrounding islands and measures a total of 1,191.39 square kilometres (460.00 sq mi) including its territorial water. Its largest island, Culion Island, has an area of 389 square kilometres (150 sq mi).[6] It is bounded on the north by Busuanga Island, on the east by the Coron Reef, on the south by Linapacan Island, and on the west by the South China Sea.
The Culion sea is teeming with a total of 201 fish species including commercially important fish like Lapu-lapu (Groupers), Kanuping (Sweetlip Emperor), Maya-Maya (Snapper), Tanguige (Spanish Mackerel), Dalagang Bukid (Blue and Gold Fusiliers) and Bisugo (Breams). Squid, cuttlefish, shrimps, crabs, shellfish and sea cucumber or trepang are plentiful.
Three ecosystems sustain the rich marine life of Culion: mangroves, seagrass, and corals. 17 mangrove species cover the coastline of Culion. 9 seagrass species and 47 coral genera representing 60% of the total genera found in the Philippines are found in Culion.

In the 2020 census, the population of Culion was 23,213 people,[20] with a density of 46 inhabitants per square kilometre or 120 inhabitants per square mile.
The original people of Culion are the Tagbanuas, a cultural minority group that lives by fishing and food gathering. While preserving their native customs and traditions, the Tagbanuas are greatly influenced by Muslim culture and social organization.
Early trading activities attracted people from other parts of Palawan, like Calamianen and Cuyonon, who came and stayed in Culion as their new home.
Today, however, the Tagbanuas no longer practice many of their cultural traditions and many of them have been converted to Christianity. They are largely marginalized, making up only about 8% of Culion's total population. Barangay Carabao, under Republic Act 9032, was established for these indigenous people. They were also granted Certificates of Ancestral Domain under Republic Act 8371, also known as the Indigenous Peoples' Rights Act of 1997.
The establishment of the leper colony in 1906, Hansenites and hospital staff were brought to Culion from different parts of the Philippines bringing their customs, habits, dialects, and regional characteristics, and the influx of migrants in the last three decades have understandably made Culion an heterogeneous population.

[edit]Culion
View on GrokipediaCulion, officially the Municipality of Culion, is a coastal municipality comprising 14 barangays in the northern part of Palawan province, MIMAROPA Region, Philippines, with a land area of 499.59 square kilometers and a population of 23,213 according to the 2020 census.[1] The municipality centers on Culion Island, the seventh-largest island in the Philippines, along with 41 minor surrounding islets, characterized by low population density of 46 persons per square kilometer and an elevation averaging 38.3 meters above sea level.[1] Historically, Culion gained international notoriety as the site of the Culion Leper Colony, established in 1906 under American colonial administration as a compulsory quarantine facility for leprosy patients, which peaked at nearly 7,000 residents by 1933 and functioned as a pioneering center for leprosy treatment and research, including chaulmoogra oil therapy, amid high initial mortality rates exceeding 60% in early years.[2] Today, following the colony's decline after World War II due to revised segregation policies and effective treatments like dapsone, Culion has transitioned into a self-reliant community emphasizing sustainable development as an eco-historical tourist destination, with an economy rooted in fishing, agriculture, and eco-tourism while preserving its leprosy archives and natural environment.[2][3]
History
Pre-colonial and Spanish colonial era
Culion Island, located in the Calamian archipelago of Palawan, was settled by the Tagbanua, an indigenous ethnic group with roots tracing to ancient Palawan populations. These coastal and riverine dwellers engaged in subsistence activities aligned with the island's geography, as evidenced by their historical presence documented in ethnographic records.[4] Archaeological excavations in northern Palawan, such as the Ille site, reveal human activity from the Terminal Pleistocene through the Late Holocene, including faunal remains indicative of early hunting and gathering practices by ancestral groups linked to the Tagbanua.[5] While specific artifacts from Culion remain undocumented, the broader regional continuity supports pre-colonial habitation patterns without evidence of large-scale settlements or external influences prior to European arrival.[6] Under Spanish rule from 1571 to 1898, Culion's remote position amid Palawan's islands facilitated its use as an exile site for criminals and rebels, capitalizing on natural barriers for isolation rather than formal infrastructure.[7] This practice reflected broader colonial strategies in the archipelago, where distant locales minimized escape risks and administrative oversight.[8] Pre-1906 records show no concentrated leprosy presence on Culion, despite the disease's occurrence in the Philippines during the Spanish era through sporadic cases tied to trade and migration.[9] Empirical accounts emphasize isolation measures for affected individuals elsewhere, with Culion's selection later by American authorities predicated on its uninhabited or low-population status at the time.[2]Establishment and expansion of the leprosarium
The Culion leprosarium was established in 1906 under the American colonial administration in the Philippines, spearheaded by Victor G. Heiser, the Chief Quarantine Officer and Director of Health, to centralize the isolation of individuals diagnosed with leprosy amid concerns over its spread through close contact.[2] Culion Island was selected for its remote location in Palawan, facilitating geographic separation from population centers to interrupt potential transmission chains, a policy grounded in contemporaneous medical understanding of the disease's contagious nature.[10] The initial transfer occurred on May 27, 1906, when 365 patients were shipped from Cebu aboard vessels including the Panlilio and Mindanao, marking the start of mandatory segregation efforts.[11] Subsequent relocations from existing facilities in Manila, Cebu, and other areas like Nueva Ecija consolidated patients into Culion, supported by Act No. 1711 passed in 1907, which mandated the compulsory apprehension, detention, and segregation of those affected to curb public health risks.[2] This centralization addressed fragmented prior approaches under Spanish rule, where lepers were confined in urban asylums without systematic isolation, leading to perceived inefficacy in preventing contagion.[12] By the 1920s, the patient population had surged beyond 6,000, establishing Culion as the world's largest leprosarium and necessitating expansive infrastructure development.[13] To sustain the isolated community, American authorities constructed essential facilities including hospitals, schools, residential quarters, and utilities such as water systems and power generation, transforming Culion into a self-contained township designed for long-term quarantine.[14] These developments prioritized operational independence, enabling the colony to house and provision thousands while minimizing external dependencies and reinforcing the quarantine's public health rationale through enforced containment.[10] The expansion reflected rising case detections and policy commitments to comprehensive isolation, with the island's growth underscoring the scale of leprosy's prevalence in early 20th-century Philippines.[15]Medical practices and research advancements
Initial treatments at the Culion leprosarium relied on chaulmoogra oil, administered orally from 1906 to 1910, followed by hypodermic injections introduced by Victor Heiser in 1914, which were reported to produce exceptionally good results in arresting disease progression among patients.[2][16] Patient records documented partial efficacy, with the oil halting symptoms in some cases but failing to achieve bacteriological cure or reversal of advanced neural damage, reflecting the empirical limitations of pre-antibiotic therapies reliant on fatty acid derivatives to inhibit Mycobacterium leprae replication.[17] Research advancements at Culion included contributions from Howard Wade, who developed the scraped-incision method for preparing skin smears to detect leprosy bacilli, a technique that improved diagnostic accuracy by targeting deeper dermal layers where bacilli concentrate, becoming a standard in leprosy microscopy.[18] Wade's etiological studies at the facility further elucidated M. leprae pathology, including attempts to cultivate the bacterium in tissue cultures from patient samples, advancing understanding of its obligate intracellular nature despite cultivation failures that underscored the pathogen's fastidious growth requirements.[13] By the 1940s, the leprosarium transitioned to sulfone-based therapies, such as intravenous Promin (a water-soluble sulfone precursor) and later oral diaminodiphenylsulfone (DDS), which demonstrated superior bactericidal activity over chaulmoogra, reducing bacterial indices and enabling clinical remission in responsive cases.[19] The adoption of World Health Organization-recommended multi-drug therapy (MDT)—combining rifampicin, dapsone, and clofazimine—in the 1980s at Culion correlated with nationwide declines, contributing to the Philippines achieving leprosy elimination as a public health problem (prevalence below 1 per 10,000) by 1998, as verified by WHO criteria emphasizing sustained MDT coverage and relapse monitoring.[20][21]Post-World War II operations and decline
During World War II, operations at the Culion leprosarium were disrupted by the Japanese occupation of the Philippines from 1941 to 1945, which interrupted medical supply chains, patient transfers, and administrative control, though the isolated island location limited direct combat impact.[22] Post-liberation in 1945, the facility resumed under the newly independent Republic of the Philippines in 1946, with continued emphasis on isolation and supportive care amid limited wartime damage to infrastructure.[2] By the 1950s, the leprosarium's expanded infrastructure, including hospitals, housing, and agricultural lands, supported several thousand residents, including patients, their families, and staff, fostering self-sufficiency through patient-led farming and food production that reduced reliance on external rations. Chaulmoogra oil treatments persisted, but the introduction of sulfone drugs like promin in the late 1940s marked a shift toward ambulatory care, gradually curbing new admissions as provincial leprosaria absorbed milder cases.[2] The 1960s onward saw a sharp operational decline driven by medical advancements, with dapsone monotherapy enabling outpatient management and reducing active cases from thousands to hundreds by the 1980s.[2] The World Health Organization's endorsement of multi-drug therapy (MDT) in 1982, combining dapsone, rifampicin, and clofazimine, achieved cure rates exceeding 95% in treated multibacillary cases, fundamentally undermining the rationale for mandatory isolation and leading to patient discharges.[10] By the late 1980s, active cases had fallen to around 500, dropping further to dozens by the 1990s as new admissions ceased, dispelling earlier notions of leprosy's incurability through empirical evidence of bacterial clearance via prolonged MDT regimens.[23] Philippine Department of Health records confirmed this trajectory, with Culion reporting no new cases after 2006, reflecting nationwide prevalence below 1 per 10,000 by the early 2000s.[24]Transition to civilian municipality
Following the widespread adoption of multi-drug therapy for leprosy in the 1980s, active cases in Culion diminished to negligible levels, enabling the lifting of longstanding isolation restrictions that had confined the island primarily to patients and essential staff.[25] This pragmatic shift prioritized verified health outcomes, allowing gradual reintegration without sustained segregation, as outpatient treatment rendered institutional isolation obsolete.[2] Republic Act No. 7193, enacted on February 19, 1992, formally created the Municipality of Culion in Palawan province, comprising Culion Island and several adjacent islets including Malapacao, Marily, and Gumamela.[26] [27] This legislative action transitioned administrative control from the leprosarium's medical oversight to standard local governance, permitting unrestricted settlement by non-affected individuals and fostering repopulation through migration from mainland Palawan for fishing, farming, and small-scale commerce.[28] By the early 2000s, the resident population had stabilized around 5,000, integrating cured former patients—many second- or third-generation—who retained land rights and community ties amid the influx of newcomers.[29] The World Health Organization certified Culion as leprosy-free on May 26, 2006, affirming zero endemic transmission after a century of operations and validating the island's pivot to civilian normalcy based on epidemiological surveillance data.[30] In 2018, the Culion Leprosy Archives—housing over 16,000 documents, patient records, and research materials from the leprosarium era—were inscribed in UNESCO's Memory of the World Register for Asia and the Pacific, recognizing their global value in documenting leprosy control without endorsing prior coercive policies.[31] [10] Into the 2020s, tourism initiatives capitalized on this heritage, with the Culion Museum and Archives reopening to the public on April 1, 2022, after pandemic closures, drawing visitors to preserved sites like the historic sanitarium grounds.[32] The local tourism council approved a rebranding to "Paradise Regained" via Resolution 2025-2361 on September 8, 2025, emphasizing eco-historical attractions to boost visitor numbers amid Palawan's recovery to 1.527 million tourists province-wide in 2023.[33] [34] These efforts, coupled with targeted infrastructure like improved docking facilities, have supported modest economic diversification, though data indicate tourism receipts remain secondary to fisheries, contributing to per capita income growth aligned with provincial averages exceeding PHP 200,000 annually by 2023.[3]Geography
Physical features and location
Culion is a municipality in the northern portion of Palawan province, within the Calamian Islands archipelago of the Philippines, situated to the north of the main Palawan island. It encompasses Culion Island, the second largest in the group, along with 41 surrounding smaller islands and islets. The municipality's central coordinates are approximately 11.89°N latitude and 120.02°E longitude.[35][36] The land area of Culion totals 456 square kilometers, dominated by Culion Island itself. The terrain includes rugged limestone formations characteristic of the Calamian group's geology, with elevated interiors and indented coastlines featuring bays and coves. Coastal zones support mangrove ecosystems, contributing to the area's ecological structure.[36][37] Culion's surrounding waters host biodiverse coral reef systems, as documented in marine assessments of the Calamianes, where surveys around Culion Island identified diverse reef communities and several previously unrecorded coral species. These reefs form part of broader conservation efforts in the region, recognized for their role in supporting marine habitats. Proximity to neighboring Busuanga and Coron islands facilitates sea-based access, with principal connections via inter-island waterways.[38][36]Administrative barangays
Culion is administratively subdivided into 14 barangays, serving as the primary units for local governance and territorial management across its island jurisdiction.[1] These divisions were formalized under Republic Act No. 7193, enacted in 1991, which delineated boundaries from former territories of adjacent municipalities to establish the standalone municipality, incorporating areas previously under restricted leprosarium administration. Subsequent expansions via Republic Act No. 9032 in 2001 adjusted jurisdictional extents, including transfers of peripheral islands and islets, while maintaining the core barangay structure for efficient resource allocation and community oversight as mapped by the Philippine Statistics Authority. The barangays include:- Balala
- Baldat
- Binudac
- Burabod
- Culango
- De Carabao
- Galoc
- Halsey
- Jardin
- Libis
- Luac
- Malaking Patag
- Osmeña
- Tiza[1]
Climate and environmental conditions
Culion exhibits a tropical monsoon climate under the Köppen classification (Am), marked by consistently high humidity, minimal seasonal temperature variation, and pronounced wet and dry periods. Mean annual temperatures fluctuate between 26°C and 30°C, with the highest averages occurring from April to June, often exceeding 31°C during daytime peaks, while nighttime lows rarely drop below 24°C.[39] [40] The wet season spans May to November, delivering the bulk of annual precipitation—typically over 2,000 mm in total—with monthly totals peaking at 300-400 mm in July and August due to the southwest monsoon and frequent convective activity. In contrast, the dry season from December to April sees reduced rainfall, averaging under 100 mm monthly, though occasional easterly trades can introduce brief showers. These patterns align with broader Palawan trends, where interannual variability is influenced by El Niño-Southern Oscillation events, occasionally intensifying droughts or floods.[39] [41] As part of the typhoon-prone Philippine archipelago, Culion faces recurrent threats from tropical cyclones, averaging 8-9 landfalling systems annually nationwide, though the Calamian Islands experience fewer direct hits than eastern regions. Super Typhoon Haiyan (Yolanda) in November 2013 generated winds up to 215 km/h and storm surges that damaged coastal infrastructure and uprooted vegetation across Culion's barangays. Similarly, Typhoon Rai (Odette) in December 2021 caused widespread erosion and habitat disruption in Palawan, underscoring the islands' exposure despite their western position offering partial shielding. Rising sea levels, projected at 0.3-1.0 meters by 2100 under IPCC scenarios, exacerbate risks to Culion's fringing reefs and intertidal zones through increased salinization and inundation.[42] [43] [44] Environmental conservation has gained prominence since the leprosarium's phase-out in the 1990s, emphasizing habitat restoration amid climatic pressures. Mangrove ecosystems, vital for coastal defense against storms and erosion, are actively rehabilitated through initiatives targeting 15 barangays, enhancing fish nurseries and carbon sequestration. Culion participates in the Calamianes Marine Protected Area Network, spanning Busuanga, Coron, Culion, and Linapacan, which safeguards coral reefs and seagrass beds from overexploitation and bleaching events linked to warming waters. These efforts, supported by local foundations, prioritize no-take zones and community monitoring to bolster resilience without overlapping economic exploitation.[45] [46][47]Demographics
Population trends and statistics
The population of Culion has exhibited consistent growth since the mid-1990s, coinciding with the decline of the leprosarium's patient intake and the transition to a civilian municipality. Census figures indicate an increase from 13,024 residents in 1995 to 23,213 in 2020, driven by natural increase and inward migration following reduced isolation measures.[1]| Year | Population | Annual Growth Rate (%) |
