The birth rate is defined as the number of live births per 1,000 women of childbearing age (15-44 years). Sustained low birth rates may indicate that the population is aging, and sustained high birth rates may predict a much younger age structure in the population. It can be helpful to understand how the birth rate changes for different maternal age groups and for different racial and ethnic backgrounds, and how these births are distributed in a population.
