- Demographers study the determinants and consequences of population composition & processes
- Demographers study multi-level demographic patterns with multi-level contextual effect designs or spatial modeling, with levels often involving:
- Macro: nations, states, communities, group aggregates
- Meso: cohorts
- Micro: individuals, families/households
- Demographers use defined populations and representative, probability samples to be able to generalize results to that population.
