High-priority distinctions
- Arithmetic, physiological, and agricultural density measure different relationships between population, total land, arable land, and farmers.
- DTM stage vs. population-pyramid shape: related evidence, but not interchangeable terms.
- NIR vs. total population change: natural increase excludes migration.
- Push/pull factors vs. intervening opportunities or obstacles: reasons for movement versus conditions altering the route or destination.
- Refugee, asylum seeker, and IDP: legal and spatial categories that should not be treated as synonyms.
Apply it
Use demographic evidence to explain a consequence: school demand, labor supply, pensions, health care, housing, political representation, resource pressure, or migration policy.
