Three demographic measures that often closely parallel each other in terms of global distribution are:
-
Fertility Rate: The total fertility rate (TFR) reflects the average number of children a woman would have over her lifetime. Regions with higher fertility rates tend to be in poorer or less developed areas, often correlating with lower levels of education, particularly for women.
-
Infant Mortality Rate: This measure indicates the number of infant deaths per 1,000 live births. Higher infant mortality rates are typically observed in the same regions with high fertility rates, particularly where access to healthcare is limited and living conditions are poorer.
-
Poverty Rate: The poverty rate measures the percentage of the population living below the poverty line. Regions with high poverty rates often exhibit both high fertility rates and high infant mortality rates, as economic instability can contribute to both inadequate healthcare and family planning resources.
These three demographic measures tend to exhibit similar geographic and socioeconomic patterns, often influenced by factors such as economic development, healthcare accessibility, and education levels.
