Total Fertility Rate (TFR)

What is Total Fertility Rate (TFR)?

Total Fertility Rate (TFR) is the average number of children a woman is expected to have during her reproductive years (typically 15-49 years), assuming current age-specific fertility rates remain constant.

Historical Background

TFR is a key indicator used to assess population growth potential. A TFR of 2.1 children per woman is considered the replacement level fertility rate, needed to maintain a stable population size in the long run.
