Population Growth Rate

Usage

{{PGR|first year|first population|second year|second population}}

This template quickly calculates the population growth rate given two pairs of years and populations using the formula from Population growth:

$PGR={\frac {\ln(P(t_{2}))-\ln(P(t_{1}))}{(t_{2}-t_{1})}}\times 100\%$

Examples

• {{PGR|1980|110043|1990|180288}} → "4,94%"
• {{PGR|1969|4534252|1997|3928542}} → "−0,51%"
