Template:PAGR/doc

Usage
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.
