Fertility Rate
Fertility rate refers to the average number of children that a woman is expected to have during her lifetime, based on current birth rates. It helps measure and understand population growth or decline. A high fertility rate can indicate a growing population, often due to cultural, economic, or social factors, while a low fertility rate can signal potential challenges like an aging population. Generally, a replacement fertility rate of about 2.1 children per woman is needed for a population to maintain its size without immigration.

The fertility rate measures the average number of children a woman is expected to have during her lifetime, assuming current birth rates remain constant. It reflects the reproductive behavior of a population and is typically expressed as the number of live births per woman. A fertility rate of about 2.1 is considered “replacement level,” meaning the population can maintain its size without immigration. Rates above or below this level can indicate population growth or decline, affecting economic, social, and environmental factors within a society.

Fertility rate refers to the average number of children a woman is expected to have during her reproductive years, typically measured per 1,000 women. It's a key demographic indicator that helps understand population growth or decline. A higher fertility rate can indicate a younger population and potential for growth, while a lower rate may suggest aging populations and potential challenges, such as labor shortages. Generally, a fertility rate of about 2.1 children per woman is considered the replacement level, meaning a population can sustain itself without growth or decline.
