Calculate total and annualized population growth between two population values.

How it works

Enter compatible geographic values. The calculator validates the numerical inputs and applies Total growth (%) = (Final - Initial) / Initial × 100; Annualized growth (%) = ((Final / Initial)^(1 / Years) - 1) × 100.

The formula

Total growth (%) = (Final - Initial) / Initial × 100; Annualized growth (%) = ((Final / Initial)^(1 / Years) - 1) × 100

Variables: Initial population = Initial population; Final population = Final population; Years = Number of years.

Worked example

Example: Population increasing from 100,000 to 121,000 in two years gives 21% total growth and 10% compound annualized growth.

Frequently asked questions

What is this Geography calculator intended for?

It is an educational tool for map scale, population and spherical geographic calculations.

Is the result suitable for professional surveying or official statistical reporting?

Not automatically. Surveying can require ellipsoidal geodesy, a specified datum and higher-precision methods, while official statistics can use defined population, land-area and growth methodologies.
