total fertility rate
Quick Summary
The total fertility rate (TFR) is the average number of children born to women during their reproductive years. A TFR of 2.1 is considered the replacement rate, meaning the population will remain stable if this number is consistently met, assuming no immigration or emigration.
Globally, the TFR has declined significantly since 1970. Factors contributing to this decrease include increased access to contraception and education for women, higher living costs, and family planning policies. While some governments have implemented pro-natalist policies to encourage higher birth rates, their long-term effectiveness is debated.
Low fertility rates can lead to an aging population, potential labor shortages, and economic challenges. However, some argue that a smaller population could ease pressure on environmental resources and allow for greater investment in human capital and technology.
