The American population is due to grow by 49% over the next half-century, according to latest projections.

The US Census Bureau estimates that the nation's population will grow to 420 million in 2050, up from the 282m recorded in 2000. In contrast, most European countries are expected to experience decline over the same period.

US growth will be driven by expansion in the Hispanic and Asian communities. The former is expected to grow by 188% between 2000 and 2050 to 102.6m; the latter by 213% to 33.4m.

The black population is also due for rapid expansion, with a projected size of 61.4m in 2050, a leap of 71% on 2000.

In contrast, the non-Hispanic white population is forecast to rise by just 7% to 210.3m. Such slow growth means this group will account for 50.1% of all Americans in 2050, down from 69.4% in 2000.

By gender, the female population is expected to rise 48.5% to 213.4m, while the number of men will jump 49.2% to 206.5m. Meanwhile, the population will continue to grow older -- 20.7% of Americans will be aged over 65 by 2050, up from 12.4% in 2000.
