The muddy alleyways off Laosanyu Road teem with thousands of men, women and children, all of them from somewhere else, usually the country's vast and largely impoverished rural interior. Many have lived in and around Beijing for years or even decades; others count their time here in months or days. Rescuers carry a man injured during a traffic accident at a section of the Beijing-Hong Kong-Macau Highway in Xiaogan, Hubei province October 16, 2010. The death toll has risen to eight in a highway pile-up accident involving more than 10 vehicles in south China's Hubei Province on Saturday according to traffic police, Xinhua News Agency reported. Reuters Crash Deadly pile-up in southern China The "farmer-workers," as they are known in Chinese, are at once the engine of this country's rapid economic growth, and those it has left behind. And no one knows for certain just how many of them there are. More than six million people - a number almost three times the size of the People's Liberation Army, and larger than the population of Denmark - will on Monday fan out across this country's 31 provinces to begin China's first national census in a decade. Though a population survey carried out at the end of last year estimated the population of the People's Republic of China at 1.334 billion, there are far too many unknowns for that number to be considered definitive. Some demographers believe the real number of Chinese may be closer to 1.5 billion. There are several reasons China's government has a poor handle on the number of people it rules, but the biggest one is that the country is in the midst of the world's biggest-ever peacetime migration.

Close share panel × The United Nations estimates that on Monday 31 October the world's population will reach seven billion. But how accurate is this figure? Not only is the world's population supposedly reaching seven billion today, the charity Plan International has anointed a girl born in India as the seven billionth.In margin of error reality, things are much less clear.The UN's population estimates chief, Gerhard Heilig, describes it as "nonsense" to suggest anyone could pinpoint where the seven billionth child will be born.And he says the UN recognises that its own figures come with a 1-2% margin of error. Today's population could actually be 56 million higher or lower than seven billion, Mr Heilig says. "There is a window of uncertainty of at least six months before and six months after the 31 October for the world population to reach seven billion," he told the BBC. You are always going to be essentially guessing… We will never have a true, definitive figureProfessor Mike Murphy, London School of Economics The UN Population Division website adds that no-one can determine the date with an error margin smaller than about 12 months, as even the best censuses have "inevitable inaccuracies"."In fact, due to very poor demographic statistics in a significant number of developing countries the uncertainty may be even larger."The UK census of 2001 illustrates the problem. The population had been thought to be about 60 million, while the census showed it was closer to 59 million."The British figures were revised by more than 1% in 2001 and that's in a highly developed country," says London Sch
