Birth rate, crude (per 1,000 people)
SP.DYN.CBRT.IN
Definition
Crude birth rate indicates the number of live births occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
Methodology for Health & Population indicators
Health and population indicators come from national vital-registration systems, demographic and health surveys, and modeling by the UN Population Division and WHO. Mortality and morbidity estimates are often modeled rather than directly observed in lower-capacity statistical systems, which means some figures are interpolations between survey years. Life expectancy is a "period" measure based on current age-specific mortality, not a forecast of how long someone born today will actually live.
How to interpret
- Always check the unit and reporting year before comparing values across countries.
- NULL or "Not available" means the World Bank did not publish a value — we never estimate.
- Year-over-year changes can be driven by methodology updates, not just real economic shifts.
