The birth rate is the total number of births in a year per 1,000 individuals in a population while fertility rate is the number of live births in a year per 1,000 women of reproductive age in a population.
Birth rate and fertility rate are very closely related terms that are very important in population biology.
Fertility rate, total (births per woman) - European Union ( 1 ) United Nations Population Division. Fertility rate (FR) is the number of live births per 1,000 women in the reproductive age, which is 15 to 49.
However, when the TFR is less than 2.1 children born per woman, in a steady population, the size of the population declines. • Birth rate is a parameter of the entire population, while fertility rate is a parameter of a group of individuals in the population.

United Nations projections are also included through the year 2100. Moreover, the average global birth rate was 18.5 births per 1,000 total population in 2016 while today, the total fertility rate is 2.
