CENSUS: China has kicked off a once-a-decade census, a whirlwind 10-day head count that sees 6 million census takers scrutinize apartment blocks, scour migrant areas and scan rural villages to document massive demographic changes in the world's most populous country.

2000 TALLY: The last roundup put China's official population at 1.295 billion people, but missed migrant workers living in cities for less than six months.

THE DIFFERENCE: For the first time China will count people where they live and not where their resident certificate is legally registered. That will better track demographic changes and find the true size of China's giant cities. It also will count foreigners and people from Hong Kong and Macau.
