Define total fertility rate and replacement rate. Use them to describe the population prospects for many developed countries.
On Sep 22, 2024
The total fertility rate is the average number of children per lifetime birthed by a nation's women. The replacement rate is the total fertility rate necessary to offset deaths in a country and thereby keep the size of its population constant. For most countries, a total fertility rate is about 2.1 births per woman per lifetime. Because fertility rate tends to fall below replacement rate as countries modernize, we can expect total world population to begin declining.
