Formulas
| Indicator | Formula |
|---|---|
| population density | P = N / S, people/km² |
| natural increase | NI = births − deaths |
| birth and death rates | number of events · 1000 / N, ‰ |
| net migration | NM = immigrants − emigrants |
| total increase | TI = NI + NM |
A negative natural increase is a natural decrease. Rates are expressed per mille (‰) — per 1000 people.
Example. A country has 146.1 million people; 1.26 million were born and 1.76 million died in a year. NI = −500,000 people, rate ≈ −3.4 ‰.
