Which of the following is considered a health indicator?

Birth rates are considered a key health indicator because they provide crucial information about the reproductive health of a population. They help assess factors such as family planning, maternal and child health services, and the overall demographics of an area. High or low birth rates can indicate various social and health-related issues, including access to healthcare, economic conditions, and cultural norms surrounding family size. Moreover, they can influence public health policies and resource allocation.

In contrast, environmental quality, economic stability, and educational attainment, while important in understanding the broader context of public health, do not directly measure health outcomes or conditions in the same immediate way that birth rates do. They may impact health indirectly, but birth rates offer a more direct reflection of specific health trends and issues within a population.
