How is this data produced?
An age-specific fertility rate (ASFR) is the average number of births per 1,000 women in a specific age group. The ASFRs shown in this dataset are computed from administrative records of births registered with JPN (which record the age of the mother), as well as population data from DOSM as the denominator.
The total fertility rate (TFR) is the average number of children born to a woman who goes through her child-bearing years experiencing the ASFR of each age group. It is computed by:
- Summing the ASFRs of all age groups, then
- Multiplying the number by 5 to account for the size of each age group, and finally
- Dividing by 1000 (to convert the figure from per 1000 women to per woman.
What caveats I should bear in mind when using this data?
ASFR values are based on the actual number of live births per 1000 women in each 5-year age group. However, when interpreting TFR values, it is important to note that the TFR is based on a hypothetical woman who goes through her child-bearing years experiencing the ASFR of each age group. This is not equivalent to the actual average number of children born to currently-living female citizens aged 15-49, as this number would be a reflection of past rather than current ASFR values.

Metadata
Dataset description
Total fertility rate (TFR) and age-specific fertility rates (ASFR) from 1958 to the present at national level.
Variable definitions
- Date
- Age Group
- Fertility Rate
Name in Dataset | Variable | Definition |
|---|---|---|
date (Date) | Date | The year of the recorded fertility rate in YYYY-MM-DD format, with MM-DD set to 01-01 as the data is at annual frequency. |
age_group (Categorical) | Age Group | 5-year age group for fertility rates (15-19, 20-24,...,45-49), or the Total Fertility Rate ('tfr'). |
fertility_rate (Float) | Fertility Rate | Fertility rate for the specific age group (ASFRs) or the total fertility rate (TFR). ASFR values are the number of live births per 1000 women in the age group, whereas TFR values are the average number of children born to a woman who goes through her child-bearing years experiencing the ASFR of each age group. |
