Thailand Population Growth
Annual population growth rate SP.POP.GROW
Thailand's population growth was -0.14% in 2025, ranked 183rd globally. This represents a 186.7% decrease from 2024. Data from World Bank, covering 1961–2025.
Overview
Thailand's population growth stood at -0.14% in 2025, a decline of +0.09pp from 2024. Based on recent trends, this figure is projected to reach -0.14% by 2025. Thailand ranked 183rd globally.
Thailand’s population growth has shifted from a rapid expansion of 2.93 % in 1961 to a modest decline of –0.14 % in 2025, placing the country at rank 183 globally. The all‑time peak of 2.99 % occurred in 1965, reflecting the post‑war baby boom that characterised many developing economies. Over the 65‑year span, the growth rate has steadily decelerated, crossing zero and entering negative territory for the first time in 2025. This trajectory mirrors the demographic transition experienced by peers such as Jamaica (–0.13 % in 2025) and the Slovak Republic (–0.19 % in 2025), where ageing populations and declining fertility rates are eroding natural increase. The recent trough highlights the combined impact of lower birth rates, higher life expectancy and modest net migration. If fertility remains below replacement level and migration does not offset the shortfall, Thailand is likely to continue recording population contraction, potentially prompting policy adjustments to sustain labour force size and economic growth.
