The foundation of demography lies in accurate measurement. The most common tools are , which provide a "snapshot" of a population at a specific time, and vital registration systems , which record continuous events like births and deaths.

Simple measures like the Crude Birth Rate (CBR) or Crude Death Rate (CDR) calculate events per 1,000 people. Demography: Measuring and Modeling Population P...

More complex mathematical models, such as the , allow researchers to project how specific age groups will evolve. For example, if a country has a "bulge" in its youth population, models can predict the future demand for schools, then jobs, and eventually pension systems.
