Replacement fertility is the total fertility rate at which women give birth to enough babies to sustain population levels, assuming that mortality rates remain constant and net migration is zero. [8] If replacement level fertility is sustained over a sufficiently long period, each generation will exactly replace itself. [8]
Birth rate should not be confused with the generally more useful total fertility rate, which adjusts figures to account for how many females of reproductive age there are.

Crude birth rate refers to the number of births over a given period divided by the person-years lived by the population over that period. It is expressed as number of births per 1,000 population. The article lists 233 countries and territories in crude birth rate. The first list is provided by Population Reference Bureau. [1]
The net reproduction rate (R 0) is the number of surviving daughters per woman and an important indicator of the population's reproductive rate. If R 0 is one, the population replaces itself and would stay without any migration and emigration at a stable level.

Crimea status in data unknown, I've gone with default of the original map. Total fertility rates on the left refer to the average number of children that are born to a woman over her ...
Last year, South Korea beat its own record for having the world’s lowest birth rate, reporting 0.72 births per woman for 2023, down from 0.78 in 2022. Singapore reported 0.97 births per woman ...
A 2023 map of countries by fertility rate. Blue indicates negative fertility rates. Red indicates positive rates. The total fertility rate (TFR) of a population is the average number of children that are born to a woman over her lifetime, if they were to experience the exact current age-specific fertility rates (ASFRs) through their lifetime, and they were to live from birth until the end of ...
The region of Sub-Saharan Africa has the highest birth rate in the world. As of 2016, Niger, Mali, Uganda, Zambia, and Burundi have the highest birth rates in the world. [32] This is part of the fertility-income paradox, as these countries are very poor, and it may seem counter-intuitive for families there to have so many children.
