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:

<math>PAGR = \left[ \left(\frac{P_2}{P_1}\right)^\frac{1}{t_2-t_1} - 1 \right] \times 100%</math>

where <math>P_1</math> and <math>P_2</math> are the populations in the first (<math>t_1</math>) and second (<math>t_2</math>) year.

Examples

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