Data sources

Most of the data on this page comes from the Human Fertility Database (website www.humanfertility.org) (data downloaded on December 2, 2013, last updated August 8, 2012). The data collected by the Human Fertility Database is based on government data collection by the government of Japan. Details about the modalities of data collection are available here.

Qualitative history of fertility-relevant events

Year Event Postulated effects seen in fertility statistics
1948 passage of Eugenic Protection Law legalizing abortion and facilitating the provision of family planning services This may have contributed to the rapid decline in birth rates and fertility in the 1949-1955 period.
1966 replacement of the Eugenic Protection Law by the Maternal Health Protection Law, making abortion illegal under most circumstances. The effect on fertility trends is unclear, but it seems that fertility and birth rates fell sharply from 1965 to 1966 (just as the law was coming into effect) but then rose sharply from 1966 to 1967. This may have been a consequence of anomalous measurement or other events.

Data on period fertility

Data of total indicators only without breakdown by birth order

Year CBR (births per 1000 people per year) CBR minus previous year's CBR TFR (sum of all age-specific fertility rates), ballpark for replacement fertility is 2.1 TFR minus previous year's TFR TFR40 (sum of age-specific fertility rates up to the age of 40), almost equal to TFR because births above the age of 40 are rare TFR40 minus previous year's TFR40

Data on total fertility rate broken down by birth order

The columns TFR1, TFR2, TFR3, and TFR4 describe the total fertility rates at the respective birth orders 1, 2, 3, and 4. The column TFR5+ describes the total fertility rate at higher birth orders (combined). The corresponding "proportion" columns divide the corresponding birth order TFR column by the TFR column (the total across all birth orders). For each row, the proportion columns add up to 1.
