VoICE Immunization Evidence: Demographic Transition
As child mortality declines, family size has also declined resulting in a larger, healthier workforce and increased financial savings at the family level.
Key Evidence:A study from South Africa shows that reduction in birth rate (fertility) can yield certain socioeconomic benefits. These include 1) a decrease in ratio of economically dependent people 2) increased per capita labor force and 3) increased savings. These savings can be invested in physical human capital which aids in economic growth. As average family sizes decrease, parents are likely to invest more on their child’s health and education. This in turn offers potential benefits to long term productivity in adulthood.
Declining infant and child mortality, in which immunization plays an important role, leads to lower birth rates.
Key Evidence: Declining child mortality results in decreased fertility (birth rates), influencing a demographic transition on the national and regional scale. Improvements in public health are at the heart of the this transition due to improved sanitation, immunization programs, antibiotics, and contraceptives.
