[OC] Population pyramids of some very-low-birthrate regions

Sources: Eurostat (for Spain, Germany, Italy and Poland), Akita Prefecture Population Report (Japan), data.go.kr (South Korea), Heilongjang Statistical Yearbook 2025 (China). All data are for 2024.

These regions have very low birthrates. The lowest of all is Heilongjiang with a birth rate of 3 x 1000 and an estimated TFR of 0,52 children per woman. South Jeolla in South Korea has a TFR of around 0,9 while Asturias, Dolnoslaskie and Akita are at around 1, Liguria is at 1.2 and Sachsen-Anhalt are at 1.3.

Dolnoslaskie is a bit younger than the others, as the transition happened later and the low birth rates are a recent phenomenon. OTOH, Akita and Liguria have been experiencing low birthrates since the 1950s, while Sachsen-Anhalt suffers from heavy emigration towards other german states.

Charts have been made with Excel using data for single age categories whenever available and 5 year classes otherwise.

There are other regions with extremely low birthrates around the world, particularly in LatAm, Eastern Europe, Eastern Asia and SEA (although even certain parts of Turkey are quickly approaching these levels), but the evolution is very recent so their pyramids don't look quite as bad yet, or recent data are difficult to find (which is the case for Thailand for instance).
