Other forms: birthrates
A birthrate is the number of babies born during a specific time period within a certain population.
When experts calculate how much a country or region's population is growing or shrinking, they compare the birthrate with rates of deaths and migration. This usually means determining the number of live births for every population of 1,000. Birthrate is figured using census data and a worldwide registration system that records new births. From the 1950s to the 2020s, the average global birthrate has significantly and consistently declined, though the global population has greatly increased.
