Fertility rates in select Axis countries during and after World War II 1939-1950
Between 1939 and 1950, Japan's annual fertility rate fluctuated between 3.1 and 4.4 births per woman, before spiking to 4.6 in 1947. This was the highest of the Axis powers listed, as European figures were generally much lower at this point in history. The increase in fertility that followed the Second World War was part of the global baby boom of the mid-twentieth century.
