Sign in to saveAlso known as birthrate
total number of live births per 1,000 population divided by the length of a given period in years
A birth rate measures how many babies are born in a population each year, expressed as the number of births per 1,000 people. It matters because it helps governments and researchers understand whether a population is growing, shrinking, or staying stable, which affects planning for schools, jobs, healthcare, and other public services.

Countries by birth rate
Birth rate, also known as natality and crude birth rate, is the total number of live human births per 1,000 population for a given period divided by the length of the period in years. The number of live births is normally taken from a universal registration system for births, or population counts from a census. The birth rate (along with mortality and migration rates) is used to calculate population growth. The estimated average population may be taken as the mid-year population.
