Demographic Transition Insights
The Crude Birth Rate (CBR) measures the number of live births occurring among the population of a given geographical area during a year, per 1,000 mid-year population. From 37.8 in 1950 to 18.0 in 2020, global CBR fell by over 52%, driven by urbanization, expanded female education, access to healthcare, and economic transformation across developing and developed nations alike.
