The Human Fertility Database (HFD) serves as a premier scientific data resource, offering comprehensive information on fertility trends across developed countries. As an open-access platform, the HFD provides detailed historical and contemporary data on both period and cohort fertility, meticulously categorized by the age of the mother and by birth order. The database prides itself on employing uniform methodologies which promote data comparability across different countries and time periods, while adhering to stringent standards for data verification and documentation.

Among its offerings, the HFD features summary indicators, including total fertility rates and mean ages at birth, readily accessible through Excel tables for ease of use. Currently, it encompasses detailed fertility data from a diverse array of countries, including Canada, Germany, Japan, and the U.S.A., with plans for continuous updates and the inclusion of additional nations. The HFD remains committed to fostering international collaboration and open data access, making it an invaluable resource for researchers and policymakers alike.
