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.
A study from South Africa shows that reduced birth rates (fertility) leads to: 1) “decreasing ratio of economically dependent people” 2) “increasing labour force per capita” 3) “[increased] saving’s 4) “savings can be invested in the physical and human capital needed for economic growth” 5)”As average family size decreases, parents are likely to invest more in the education and health of each child, leading to improved productivity in adulthood.”
Declining infant and child mortality, in which immunization plays an important role, leads to lower birth rates.
Declining child mortality results in decreased fertility, ushering in demographic transition on the national and regional scale. “Improvements in public health are at the heart of the demographic transition. Improved sanitation, immunization programs, antibiotics, and contraceptives initiate the declines in mortality that lead to declines in fertility, which together cause changes in the age distribution and size of a population.”
