Total fertility rate of Mexico 1900-2020

The fertility rate of a country is the average number of children that women from that country will have throughout their reproductive years. In 1900, Mexican women of childbearing age would go on to have approximately 6.8 children on average over the course of their lifetime, however this number dropped to 5.6 by 1920, partly because of the Mexican Revolution (1910-1920). The fertility rate increased again over the course of the next sixty years, reaching 6.8 in the 1950s and 1960s, during the worldwide baby boom. However, Mexico's fertility rate has been decreasing steadily since 1970, and is expected to reach it's lowest figure ever in 2020, where the fertility rate will be 2.1 children per woman.

一国之生育率系指该国女性在其生育期内平均所育子女的数量。以1900年为例，墨西哥育龄女性在其一生中平均将生育约6.8个子女。然而，至1920年，此数字降至5.6，部分原因可归咎于墨西哥革命（1910-1920年）。随后六十年间，生育率再次攀升，于20世纪50至60年代达到6.8，正值全球婴儿潮时期。然而，自1970年起，墨西哥的生育率持续下降，预计在2020年将达到历史最低点，届时女性平均生育子女数将为2.1。
