Short-Term Fertility Fluctuations

In response to the COVID-19 pandemic, the HFD team established a new data resource: Short-Term Fertility Fluctuations (STFF) data series. The STFF series complements the HFD by providing up-to-date data on live births by month for selected countries.

STFF data are published under CC BY 4.0 license.

For citing STFF data, please follow the HFD data citation guidelines.

STFF data can also be explored using our online STFF visualization toolkit.

Here you can download the following data and documentations:

  • STFF Metadata: information about country-specific data and data sources.
  • STFF Methodological Note: description of this data project, including data collection, data processing, and methodology.
  • Crude birth counts and TFR (xlsx or pooled csv): monthly counts of live births and monthly and annual TFRs.

 
Crude indicators do not allow direct comparison across countries and over time as they are affected by seasonality in childbearing. To provide comparable indicators, we publish seasonally and calendar adjusted data.

  • Seasonally- and calendar-adjusted data (xlsx or pooled csv): monthly counts of live births and monthly TFRs for selected countries.
  • Original data (country-specific csv files in one zip file): original birth counts in standardized format.

 
Note: Data on monthly TFR are preliminary. We are still working on the methodology and may revise it soon.
