The increasing influx of migrant workers has helped push this
metropolis' population by almost 11 percent to nearly 18 million
since 2000, said a statistic report released this week.
The population rise includes new immigrants to the city and new
arrivals at its maternity wards.
The comparatively higher birth rates among migrant families in
2005 gave the city its first positive birth-death ratio since 1993,
said the report of the municipal statistics bureau, part of a
nationwide population survey.
Shanghai's residential population rose to 17.78 million in 2005,
comprising 13.4 million people with residency permits and 4.38
million migrants who lived in the city for more than six months,
the report said.
The population increased by 1.7 million since 2000, and more
than 80 percent of the newcomers were migrants, it said.
"Migrant workers have become an indispensable part of the city's
economy by doing things local residents are not willing to do," Hu
Suyun, a researcher of the Shanghai Academy of Social Sciences, was
quoted as saying by Shanghai Daily.
The immigrants often take jobs as construction workers, maids,
waiters, waitresses and vegetable dealers, the newspaper said.
The survey indicated they also tend to have more babies than the
typical long-term Shanghai resident.
Shanghai's natural population growth rate reached 0.096 percent
last year. Of the 123,900 babies born, one-third were delivered by
migrant mothers.
The increasing number of migrant people has changed the city's
population structure, the statistic report said.
Experts worry, however, that the soaring population may deplete
the city's resources and exhaust its environment.
The survey also pointed up the continuing challenge brought by
the city's aging population, the result of a baby boom in the
1950s. People age 60 or older accounted for 19.6 percent of the
city's population last year compared with 18.3 percent in 2000.
"Shanghai will be 10 years ahead of the rest of China in terms
of its aging society," the statistics bureau predicted.
