Source of Data
Data
in this chapter are prepared by the Department of Population and Employment
Statistics of the National Bureau of Statistics. In tables 4-1 and 4-2, figures
for 1982-1989 have been adjusted in line with the data from the population
censuses of 1982 and 1990, figures for 1990-2000 have been adjusted on the
basis of the 2000 population census, figures for 2001-2004 are estimates from
the annual national sample survey on population changes, figures for 2005 are
estimated from the National Sample Survey of 1% of Population, while figures
for other years are statistics derived from household registration. Data in
Table 4-3 are estimates from the 2005 National Sample Survey of 1% of
Population. Date in Table 4-4 are from the national and
provincial communiqués of the key results of the 2005 National Sample Survey of
1% of Population. Data in Table 4-5 present the main results from the five
national population censuses. Data in Table 4-6 are compiled from the 1990 and
2000 population censuses. Data in tables 4-7 to 4-18 are the sample results of
the 2005 National Sample Survey of 1% of Population.
The
National Sample Survey of 1% of Population adopted a multi-stage stratified
systematic PPS cluster sampling scheme, taking the whole nation as the
population and each province, autonomous region or municipality as the
sub-population. A total of 16.99 million people were selected from 77,417
survey districts in 21,181 townships (towns and urban neighborhood committees)
in 2,869 counties (cities and districts) of the 31 provinces, autonomous
regions and municipalities. The weighted estimation procedure suggested that
the birth rate was 12.40 per thousand, the death rate was 6.51 per thousand and
the natural growth rate was 5.89 per thousand for
