What is the Crude Birth Rate formula used to determine?

The Crude Birth Rate (CBR) is a demographic measure that refers specifically to the number of live births in a given year per 1,000 people in the population. This formula effectively captures the fertility level of a population and provides insights into the growth and demographic structure of a region.

When calculating the CBR, the total number of live births within a specific timeframe, usually a year, is divided by the total mid-year population and then multiplied by 1,000 to make it a rate per thousand people. This metric is crucial for understanding population dynamics, including trends in growth or decline, the potential for population aging, and the need for services related to children and families.

The other options do not pertain directly to the Crude Birth Rate and serve different demographic functions. Understanding the CBR can inform government policy, health services, and social planning, making it a fundamental concept in population studies.
