Everyone aged 30–39. As of the 1st of each month. Final figures (確定値, in thousands) through March 2026; later months are the Bureau's provisional estimates (概算値, in ten-thousands), replaced as each month is finalised about five months on. Figures from October 2025 will be restated once the 2025 Census counts publish.
