Human Multiple Births Database (HMBD) - static data deposit

The Human Multiple Births Database (HMBD) gathers the number of twin births and the twinning rates for countries with reliable statistics. The database also provides statistics on other multiple births (i.e., triplets, quadruplets, etc.) whenever possible.

As of 06/10/2022, the HMBD includes data for 25 countries. For each country, data go back as far into the past as possible and extend until the most recent year with available data. Data for each country are updated anually, if possible. 

The HMBD is available online at: https://www.twinbirths.org/en/

Here, in this figshare data deposit, you will find a static version of the HMBD as of 06/10/2022 (please refer to the "readme.txt" file for a detailed explanation of the contents of this deposit).
