==Total fertility rate==
 
===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.

===Data 1800 onward: lower quality data based on reconstruction from other data===
 
The data here are lower quality than the other data, even for recent years. They are based on various reconstructions and estimates, and are not sufficiently reliable for calculating year-on-year changes. However, broad trends may still be discerned.
 
An example to illustrate the lower quality of the Gapminder data is that the Gapminder data does not pick the sudden fertility dip in 1966, whereas the HFD data does.
 
The data sets correlate highly. For the years 1947-2009, where both data sets are available, the correlation is 0.993, indicating near perfect agreement in the ''trend''. The values themselves differ only slightly, both additively and multiplicatively, as the table below shows. If we exclude the anomalous year 1966 from the assessment, the correlation rises to 0.996.

This page gives information of type period fertility about the country Japan.
See all pages giving information on period fertility for particular countries|See all pages giving information about Japan

Data sources

Some data on this page comes from the Human Fertility Database (website www.humanfertility.org) (data downloaded December 2, 2013, last updated by HFD August 8, 2012). The data collected by the Human Fertility Database is based on government data collection by the government of Japan. You can download the data yourself here. Details about the modalities of data collection are available here. Where available, we use HFD data because of its higher reliability.

Total indicators only without breakdown by birth order

Total indicators with year-on-year differences (change measured additively)

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

Total fertility rate

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.

Data 1800 onward: lower quality data based on reconstruction from other data

The data here are lower quality than the other data, even for recent years. They are based on various reconstructions and estimates, and are not sufficiently reliable for calculating year-on-year changes. However, broad trends may still be discerned.

An example to illustrate the lower quality of the Gapminder data is that the Gapminder data does not pick the sudden fertility dip in 1966, whereas the HFD data does.

The data sets correlate highly. For the years 1947-2009, where both data sets are available, the correlation is 0.993, indicating near perfect agreement in the trend. The values themselves differ only slightly, both additively and multiplicatively, as the table below shows. If we exclude the anomalous year 1966 from the assessment, the correlation rises to 0.996.
