The demographic foundation for all of Spectrum’s health modules. Here you can directly project the population for an entire country or region based on assumptions about fertility, mortality, and migration.

The RADAR Sample Size Calculator is an online platform for teams looking to implement household surveys to calculate sample size.

When fertility is high the age structure of the population resembles a broad-based pyramid with a large percentage of children compared to the working age population that supports them, as in the example of Uganda in the pyramid on the right. This makes it difficult for families to save money and to invest in the health and education of each child. As fertility declines the age structure changes to one where there may be 2 or 3 people of working age to support each child, as in the example of Thailand in pyramid on the left. This creates an opportunity for savings and investment that is called the ‘demographic dividend’. It was an important factor in the rapid economic growth of many Asian countries.

RAPID (Resources for the Awareness of Population Impacts on Development) projects the social and economic consequences of high fertility and rapid population growth for such sectors as labor, education, health, urbanization, and agriculture. This program is used to raise policymakers' awareness of the importance of fertility and population growth as factors in social and economic development.
