Shanghai had 22.21 million residents by the end of 2010 – 14.12 million with registered residency and 8.3 million migrants who lived in the city for more than six months.
Population density in the city last year was 3,503 people per square kilometer, more than 20 times China’s national level.
That was an increase of 699 people compared to 2005.
Of the 14.12 million registered residents, about 200,000 were staying in other provinces or countries and so were not included in the total figure, Shanghai Population and Family Planning Commission said recently.
Officials said there were four features which stood out in regard to the city’s population in the past five years: the rapid rise in the number of migrants; the imbalance between the old and young; the rise in population density; and the increase in life expectancy.
Registered people’s life expectancy grew from 80.13 years in 2005 to last year’s 82.13.
Officials said Shanghai had a serious aging problem, as the registered population over the age of 60 had grown from 2.66 million in 2005 to 2009’s 3.16 million, the latest figures available, with their proportion of the total registered population rising from 19.58 percent in 2005 to 2009’s 22.54 percent.
The registered population below the age of 14 was 1.17 million in 2009, 8.3 percent of the total and 10.2 percentage points lower than the national standard. Shanghai had 19.21 million residents in 2009, of whom 13.79 million were registered.
