Per Annum Growth Rate

Usage

{{PGR|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:

$PAGR=[{\left(\frac{P_2}{P_1}\right)}^{\frac{1}{t_2-t_1}}-1]\times 100\mathrm{\%}$

where $P_1$ and $P_2$ are the populations in the first ($t_1$) and second ($t_2$) year.

Examples

• {{PAGR|1980|110043|1990|180288}} → "5.06%"
• {{PAGR|1969|4534252|1997|3928542}} → "-0.51%"
