Annual population growth rate SP.POP.GROW
Tanzania's population growth was 2.84% in 2025, ranked 20th globally. This represents a 1.1% decrease from 2024. Data from World Bank, covering 1961–2025.
Overview
Tanzania's population growth stood at 2.84% in 2025, a decline of +0.03pp from 2024. Based on recent trends, this figure is projected to reach 2.84% by 2025. Tanzania ranked 20th globally.
Tanzania’s population growth rate has remained remarkably stable over the 65‑year series, slipping only marginally from 2.85 % in 1961 to 2.84 % in 2025, which places the country at the 20th highest rate worldwide. The highest annual increase occurred in 1994 when the rate surged to 3.84 %, while the lowest point was recorded two years later at 1.83 % in 1996, illustrating a brief post‑boom slowdown before the long‑term plateau. Compared with peer nations of similar demographic momentum, Tanzania’s growth is slightly below Mauritania’s 2.92 % and Mozambique’s 2.92 % but above Zambia’s 2.76 % and Bahrain’s 2.64 %. The persistence of a near‑constant growth rate suggests that fertility levels and life‑expectancy improvements have balanced each other for decades. Future shifts in education, urbanisation and health policy could either accelerate the decline in growth or sustain the current trajectory, shaping the country’s demographic outlook in the coming years.
