Sri Lanka

Sri Lanka is an island in the Indian Ocean, south of India. Its stable international identifiers come from the UN Statistics Division and ISO, and its administrative structure involves two official seats: Colombo, the commercial hub, and Sri Jayawardenepura Kotte, the legislative centre. This guide lays out those fixed codes, explains how to verify changing figures yourself, and clarifies the difference between statistical categories and political claims. For travel, visa, or security information, always consult your own government’s official travel advisory.

Fixed identifiers

These identifiers are assigned by international standards bodies and do not change with elections, economic data, or administrative reorganizations:

• UN M49 code: 144
• ISO alpha-2: LK
• ISO alpha-3: LKA
• UN region: Asia
• UN subregion: Southern Asia
• UN member state: Yes
• World Bank capital field: Colombo

The codes come from the United Nations Statistics Division’s M49 framework, which is a statistical tool, not a political or territorial claim. The M49 overview is maintained by UNSD and is available at https://unstats.un.org/unsd/methodology/m49/overview/. The nation code and capital field are drawn from the World Bank country API (https://api.worldbank.org/v2/country/LK?format=json). The capital field in World Bank data reflects the administrative capital as reported by the government, not a UN position on sovereignty or disputed borders.

Understanding the two capitals

The World Bank lists Colombo as the capital in its country profile. Official administrative functions are located in Sri Jayawardenepura Kotte, and the distinction matters when comparing sources. Colombo serves as the commercial centre and the seat of the executive and judicial branches. Sri Jayawardenepura Kotte is the legislative seat. The World Bank “capital” field is a data convention, not a political statement. When you cross-reference datasets that use different capital conventions, note which city each source records.

How to verify current figures

No single page can keep population totals, currency values, or visa rules current. Use the primary sources below and always note the reference year for any number you quote.

Population and development data

The United Nations Statistics Division maintains the M49 framework and the UN Data portal. The UN Department of Economic and Social Affairs publishes annual population estimates and projections. The World Bank country page provides a parallel indicator series labelled SP.POP.TOTL, sourced from the UN Population Division and national statistics offices. For the most current figure, use the World Bank country API at https://api.worldbank.org/v2/country/LK?format=json and check the “date” field, which tells you the reference year of the estimate. Do not treat the figure as a live count; it is a model-based estimate between censuses. The most recent census was conducted in 2012, and the next full census has been delayed, so all current figures are projections or mid-year estimates. The Department of Census and Statistics of Sri Lanka manages the census cycle and is the primary source for survey data within the nation.

Economic indicators

Query the World Bank country API for metadata and time-series data. Use indicators such as SP.POP.TOTL for population, NY.GDP.PCAP.PP.CD for GDP per capita at purchasing power parity, and SI.POV.GINI for the Gini index. Both the World Bank and the IMF’s International Financial Statistics provide standardized economic data; check the “last updated” field on each dataset.

Currency and exchange rates

The Central Bank of Sri Lanka publishes official exchange rates. For cross-country comparisons, use the IMF’s International Financial Statistics.

Government and politics

The Parliament of Sri Lanka and the official government portal publish current leadership, election results, and legal instruments.

Travel, health, and entry requirements

Your own government’s foreign ministry travel advisory is the authoritative source for current visa, border, and safety rules. The IATA Travel Centre provides airline-verified entry requirements. For health data, consult WHO country pages and your own government’s health authority.

Culture, education, and governance scores

UNESCO Institute for Statistics publishes cultural and education data. Freedom House and Transparency International publish political rights and corruption scores with explicit methodology notes. UNDP provides the Human Development Index.

A verification checklist

• Note the reference year on every dataset you use.
• Never assume a number from a news headline matches a UN or World Bank definition.
• For the national statistical office, search the UN Statistics Division or World Bank directory.
• For the national central bank, search its official site.
• For the latest census, use the UN Demographic Yearbook.

Population estimates

Population figures for Sri Lanka are estimates, not exact counts. The most recent census was conducted in 2012; the next full census cycle is managed by the Department of Census and Statistics. All current figures are projections or mid-year estimates. The UN Department of Economic and Social Affairs publishes annual estimates and projections. The World Bank provides a parallel indicator series labelled SP.POP.TOTL, sourced from the UN Population Division and national figures. When you quote a number, always record the reference year shown in the source’s “date” field.

One fact this guide states that a competitor likely omits

The World Bank “capital” field is a data convention that lists Colombo, while the official administrative seat is Sri Jayawardenepura Kotte. Both are official, and the distinction can change which datasets you match when comparing sources.
