Template:Per annum growth rate - Simple English Wikipedia, the free encyclopedia

Usage

{{PAGR|first year|first population|second year|second population}}

This template calculates the per annum compound growth rate given two pairs of years and populations (or other time periods and units) using:

PAGR=\left[\left({\frac {P_{2}}{P_{1}}}\right)^{\frac {1}{t_{2}-t_{1}}}-1\right]\times 100\%

where $P_{1}$ and $P_{2}$ are the populations in the first ( $t_{1}$ ) and second ( $t_{2}$ ) year.

To add positive sign and color, add |color=true.
