Population Growth Rate, Average Annual

measure of the annual growth in population stock caused by births and deaths and international migration using the censal years as reference period.

Formula: r = [ (P2 / P1)1/t - 1 ] x 100
where: r = growth rate (in percent)
t = difference between two censal years
P2 = population size (later date)
P1 = population size (earlier date)
