Detailed explanation-1: -Assuming no net migration and unchanged mortality, a total fertility rate of 2.1 children per woman ensures a broadly stable population.
Detailed explanation-2: -High fertility: Total fertility levels above 5 children per woman. Replacement-level fertility: Total fertility levels of about 2.1 children per woman. This value represents the average number of children a woman would need to have to reproduce herself by bearing a daughter who survives to childbearing age.
Detailed explanation-3: -Total fertility rate is directly calculated as the sum of age-specific fertility rates (usually referring to women aged 15 to 49 years), or five times the sum if data are given in five-year age groups.
Detailed explanation-4: -The average number of children born to a woman during her lifetime. The number of live births per thousand persons in unit time.
