In 2003 sample survey on population change, whole country is regarded as population and every province, autonomous region and municipality is regarded as sub-population. The sample technique of stratified, multi-stage and cluster sampling, with probability proportionate to size is applied. There are 1.26 million persons in sample size, 990 counties (or resident groups), 3734 township (towns or streets), 6544 village groups (or resident groups) are included in the sample of 31 provinces, autonomous regions and municipalities of whole country. From weighting tabulation, population in China in the end of 2003 is 1292.27 million. In 2003, the crude birth rate is 12.41%0, and the number of births is 15.99 million; the crude death rate is 6.40%o, and the number of deaths is 8.25 million; the crude of natural increase is 6.01%o, and the number of natural increase is 7.74 million. The most of tabulation in the part of yearbook is sample data (except table 1-1). The sampling fraction in the whole country is 0.982%o.The 2000 population census covered all persons who hold the nationality of , and have permanent residing place in the People's Republic of China. The census took the de jure approach by which each person should be enumerated at his/her permanent residence and should be enumerated at only one- place. The reference time for the census was zero hour on November 1, 2000. Data for the 2000 population census referred to the permanent population at the reference time.
Two types of questionnaires (long form and short form) were used for the 2000 population census. The short form contains that reflect the basic situation of the population, while the long form include all short form items plus other items such as migration, education, economic activities, marriage and family, fertility, housing, etc. According to the Statute for the Fifth National Population Census and the Procedures for the Selection of Samples for the Long Form, households selected by a random sampling program completed the long form, and the rest of the households completed the short forms.The second part contains data from the long forms. The sampling ratio for the long forms=total population in the long forms/total population calculate by computer processing=9. 5%. The sampling ratio for various composition of the population may not be the same, as household is used as ultimate sampling unit.
