유엔 "2100년 세계인구 109억명...고령화 심화"<br /><br />The UN predicts that the world population will reach nearly 11 billion by the end of the century, though some countries will likely see their populations shrink.<br />One reason for the growth, the UN says, is a longer life expectancy, which is projected to rise from the current 72-point-6 years to around 77 years by 2050.<br />Half of the population growth between now and 2050 is expected to come from just nine countries, including India, Nigeria and Pakistan. <br />
