[单项选择]By 2030, people over 65 in Germany, the world’s third-largest economy, will account for almost half the adult population, compared with one-fifth now. And unless the country’s birth rate recovers from its present low of 1.3 per woman, over the same period its population of under 35 will shrink about twice as fast as the older population will grow. The net result will be that the total population, now 82 m, will decline to 70 m - 73 m. The number of people of working age will fall by a full quarter, from 40 m today to 30 m.
The German demographics (人口统计) are far from exceptional. In Japan, the world’s second-largest economy, the population will peak in 2005, at around 125 m. By 2050, according to the more pessimistic government forecasts, the population will have shrunk to around 95 m. Long before that, around 2030, the share of the over-65’s in the adult population will have grown to about half. And the birth rate in Japan, as in Germany, is down to 1.3 per woman. The figures ar
A. life expectancy has been going up steadily
B. there is a decline of the young population
C. in America the birth rate has gone above replacement level
D. the old population has risen sharply in USA
