What are total fertility rate facts?

The total fertility rate (TFR) is a demographic measure that estimates the average number of children a woman would have during her lifetime based on current birth rates. A TFR of approximately 2.1 is considered the replacement level, necessary to maintain a stable population without Immigration. Global TFRs have declined significantly over the past few decades, influenced by factors such as increased access to education, contraception, and changing societal norms. As of 2021, the global average TFR was around 2.4 children per woman, with notable variations between regions and countries.
