The National Population Projections suggests that the US population growth is large in terms of number but the growth rate is actually slow in the future. Since people’s life expectancy is increasing, we assume that in the average population age will increase too. What contribute to its slow rate then? It is because the fertility rate of women cannot catch up the large increase in mortality rate in the future. Also, the population race is more diverse, especially Hispanic origin. It may takes up the major element in population growth. It is surprising that non-Hispanic Whites will experience the slowest growth rate among other races.
