The total fertility rate in an economy is defined as? The birth rate minus death rate? The average number of live births a woman would have by the end of her childbearing age. [2024]

The total fertility rate in an economy is defined as:

the number of children born per 1000 people in the population in a year.
the number of children born to a couple in their lifetime in a given population.
the birth rate minus death rate.
the average number of live births a woman would have by the end of her childbearing age.

The total fertility rate (TFR) is the average number of children a woman would have at the end of her reproductive years, expressed as births per woman.
How is the Total Fertility Rate calculated?
- TFR is directly calculated as the sum of age-specific fertility rates (usually referring to women aged 15 to 49), or five times the sum if data are given in five-year age groups.
- An age- or age-group-specific fertility rate is calculated as the ratio of annual births to women at a given age or age group to the population of women at the same age or age group in the same year for a given country, territory, or geographic area.

A total fertility rate (TFR) of 2.0 is the replacement rate, which means that a population can replace itself from one generation to the next without external migration.

Replacement level fertility is the total fertility rate—the average number of children born per woman—at which a population exactly replaces itself from one generation to the next, without migration.
This rate is roughly 2.1 children per woman for most countries, although it may modestly vary with mortality rates.
