The birth rate is a demographic measure that indicates the number of live births in a specific population over a certain period, usually expressed per 1,000 people per year. It helps researchers and policymakers understand population growth and trends. A high birth rate can lead to rapid population increase, while a low birth rate may indicate declining populations or aging demographics. Factors influencing the birth rate include economic conditions, cultural norms, access to healthcare, and education levels. For instance, countries with strong family planning programs often experience lower birth rates, while those with limited access to contraception may see higher rates. Understanding birth rates is essential for planning resources and services in areas like education and healthcare.
