What is measured

Births, deaths and migration together change population size and age structure. Life expectancy is a period estimate, not a prediction for one person.

How it works

Causes of death depend on registration and coding, so international estimates may differ from national data. The health system combines national regulation with regional service delivery.

Differences and links

Internal migration links major cities, regional centres and rural districts. International migration includes different statuses and should not be reduced to one category of “migrants.”

Limits

Net migration does not show reasons for moving or length of stay. Medical advice and individual risk cannot be inferred from aggregate country indicators.

Chronology

Chronology does not apply. The dossier describes a social system; numeric series must carry their own observation dates.

Health and population movement are measured by different systems; indicators need dates, definitions and geography.
