Asia · Southern Asia
Sri Lanka is recorded at 23.10m people in 2024, with total annual change of +130,255 under the WPP medium variant.
Sri Lanka observed 2023 population pyramid, grouped into five broad age bands from WPP single-age male and female arrays.
Population identity: births minus deaths plus net migration equals total change within the Record tolerance.
