The United Nations Population Fund ranking is based on the data for the 2022 published online.[1] The United Nations Population Fund (formerly the United Nations Fund for Population Activities - UNFPA) is an UN agency aimed at improving reproductive and maternal health worldwide. This agency collects and analyses information on demography issues based on its own work and national sources.
The
United Nations Development Group
, but it also collects and analyses information on demography issues based on international and national sources: (1) United Nations Population Division. World Population Prospects, (2) United Nations Statistical Division. Population and Vital Statistics Report (various years), (3) Census reports and other statistical publications from national statistical offices, (4) Eurostat: Demographic Statistics, (5) Secretariat of the Pacific Community: Statistics and Demography Programme, and (6) U.S. Census Bureau: International Database.
Note: Sometimes World Bank changes its figures of fertility rates for a certain year due to more accurate and updated information from sources. Because of that, sometimes it is necessary to update World Bank figures for fertility rates more than once for the same year.

ranking lists
The Population Reference Bureau (PRB) ranking list is based on the data of the 2023 World Population Data Sheet[6] published online. The PRB[7] is a private, nonprofit organization which informs people around the world about population, health and the environment for research or academic purposes. It was founded in 1929. World Population Data Sheets are double-sided wallcharts (now published online) that present detailed information on demographic, health and environment indicators for more than 200 countries.
The
online publication that presents empirical research and data that show how living conditions around the world are changing. The aim is to show how the world is changing and why. The publication is developed at the University of Oxford and authored by social historian and development economist Max Roser
.
Notes:
1- Changes in figures of fertility rates by country from one year to another do not always reflect an actual increase or decrease of fertility rates in a certain country but instead reflect a change made due to more accurate and updated information from sources.
2- Figures of fertility rates by country and their ranking are based on single referenced sources (organizations that investigate demographic issues), however, for several times, they do not always coincide with other sources, such as other organizations and the ones that are referenced in the individual demographies by country (Demographics of...), which can be accessed by clicking on the names of the countries, this is due to several reasons such as different primary sources, data quality, methodology and others.
