Africa · Western Africa
Guinea-Bissau is recorded at 2.20m people in 2024, with total annual change of +47,928 under the WPP medium variant.
Guinea-Bissau 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.
