Brief
Introduction
I. Main Contents
Data in this chapter show the basic
condition of the population in 2007 as well as previous years for the whole nation and 31 provinces, autonomous regions and municipalities
directly under the Central Government. They include the sizes of the national
population, urban population and rural population over the years; as well as
size, birth rates, death rates, natural growth rates, dependency ratio,
household size and education attainment of the population by region in 2007.
II. Sources of Data
Data in this chapter are prepared by the
Department of Population and Employment Statistics of the National Bureau of
Statistics. In tables 3-1 and 3-2, figures for 1982-1989 have been adjusted in
line with the data from the 1990 National Population Census; figures for
1990-2000 have been adjusted on the basis of the 2000 National Population
Census; figures for 2001-2004，2006， and 2007
are estimated from the annual national sample survey on population changes; figures for 2005 are estimated from the 2005 National 1%
Population Sample Survey; and figures for other years are statistics derived
from household registration. Data in Table 3-3 and 3-4 are estimated from the
2007 National Sample Survey on Population Changes.
Data in
Table 3-5 present the main results from the five national population censuses.
Data in Table 3-6 are compiled from the 1990 and 2000 National Population
Census. Data in tables 3-7 to 3-15 are the sample results of the 2007 National
Sample Survey on Population Changes.
III. Sampling Methodology
The 2007 National Sample Survey on Population Change adopted
a stratified multi-stage systematic PPS cluster sampling scheme, taking the
whole nation as the population and each province, autonomous region or
municipality as sub-populations. A total of 1.19 million people were selected
from 11,789 survey districts in 3,430 townships (towns and street committees)
in 1,894 counties (cities and districts) of the 31 provinces, autonomous
regions and municipalities. The size of the sample was thus 0.900 per thousand
of the national population. The weighted estimation procedure suggested that
the birth rate was 12.10 per thousand, the death rate was 6.93 per thousand and
the natural growth rate was 5.17 per thousand for
