Brief Introduction
I. Main Contents
Data in this chapter show the basic
condition of the population in 2009 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 2009.
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 2001-2004，2006-2009 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 2009 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 2009 National Sample Survey on Population
Changes.
III. Sampling Methodology
The 2009 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 1.16 million people were selected from 11,748
survey districts in 5872 neighborhoods in 3,460 townships (towns and street
committees) in 1,882 counties (cities and districts) of the 31 provinces,
autonomous regions and municipalities. The size of the sample was thus 0.873
per thousand of the national population. The weighted estimation procedure
suggested that the birth rate was 12.13 per thousand, the death rate was 7.08
per thousand and the natural growth rate was 5.05 per thousand for
