Sensitivity analysis of the long-term (i.e., asymptotic) population growth rate to changes in the vital rates is commonly used in management to identify the vital rates that contribute most to population growth. Population pyramids reveal markedly different characteristics for three nations: high fertility and rapid population growth (Mexico), low fertility and slow growth (United States), and very low fertility and negative growth (West Germany). Population momentum and population aging occur when an initially growing population experiences a reduction in fertility to replacement level. In summary, population momentum tends at 1st to slow down declines in rates of natural increase.
