About birth rate (Total fertility rate)

The birth rate is an indicator showing the average number of children a woman is expected to have during her lifetime. Specifically, it is the sum of age-specific fertility rates for a given year across all ages, reflecting childbearing patterns throughout a woman's reproductive years. This indicator is often compared with the "replacement level fertility" (typically 2.1 in developed countries) necessary to replace the population, and serves as a fundamental measure for understanding a society's long-term population dynamics.

There are multiple reasons why the birth rate is given significant attention. First, it is the most important indicator for predicting population growth or decline trends and is essential for estimating a nation's population structure and future labor force. Second, it is directly related to the sustainability of social security systems in aging societies and is indispensable when considering pension and healthcare expenditure burdens. Third, it affects numerous economic and social phenomena such as economic growth, labor markets, and education demand, making it an important criterion for policymaking.

Currently, the birth rates in many developed countries fall significantly below replacement level, with particularly severe declines continuing in countries such as Japan, Italy, and Germany. Globally, birth rates are declining due to factors including increased educational attainment of women, expanded employment opportunities, widespread contraceptive technology, and rising economic uncertainty. Low birth rates result in rapid aging populations and declining working-age populations, leading to reduced economic vitality and increased fiscal burdens. As a result, governments around the world are addressing declining birth rates as an important policy challenge.
