阅读理解Population Change Why is the worlds population growing？The answer is not what you might think.The reason for the explosion is not that people have been reproducing like rabbits,but that people have stopped dropping dead like flies.In 1900,people died at the average age of 30.By 2000 the average age was 65.But while increasing health was a tupical feature of the 20thcentury,declining birth rate could be a defining one of the 21st. Statistics show that the average number of births per woman has fallen from 4.9 in the early 1960s to 2.5 owadays.Furthermore,around 50% of the worlds population live in regions where the figure is now below the replacement level(i.e.2.1 births per woman)and almost all developed nations are experiencing sub-repalanement birth rate.You might think that developing nations would make up the loss(especially since80% of the worlds people now live in such nations),but youd be wrong,Declining birth rate is a major problem in many developing regions too,which might cause catastrophic global shortages of work force within a few decades. Agreat decline in young work force is likely to occur in China,for instance.Whatdoes it imply?First,China needs to undergo rapid economic development before apopulation decline hits the country.Sencond,if other factors such as technologyremain constant,economic growth and material expectations will fall well belowrecent standards and this could invite trouble. Russiais another country with population problems that could break its economicpromise.Since 1992 the number of people dying has been biggen than that ofthose being born by a massive 50%,Indeed official figures suggest the countryhas shrunk by 5% since 1993 and people in Russia live a shorter life now thanthose in 1961.Why is this occurring?Nobody is quite sure,but poor diet an aboveall long-time alcoholism have much to do with it.If current trends dont bend.Russiaspopulation will be about the size of Yemens by the year 2050. Inthe north of india,the population is booming due to high birth rates,but in thesouth,where most econmoic development is taking place,birth rate is fallingrapidly.In a further twist,birth rate is highest in poorly educated ruralarceas an lowest in highly educated urban areas.In total,25% of Indiasworking-age population has no education.In 2030,a sixth of the countryspotential work force could be totally uneducated. Onesolution is obviously to import foreign workers via immigration.As for theUSA,it is almost unique among developed nations in having a population that isexpected to grow by 20% from 2010-2030,Moreover,the USA has a track record ofsuccessfully accepting immigrants.As a result its likely to see a rise in thesize of its working-age population and to witness strong economic growth overthe longer term.
