Sampling Methodology
The statistical surveys on population which
are conducted by Department of Population and Employment Statistics of NBS are
as follows:
The national population census is conducted in the year ending with 0; the national 1 percent population sample survey is conducted in the year ending with 5; sample surveys on population changes are conducted in the rest of the years which cover about 1 per thousand of the total population of the country. The sample survey on population change takes the whole nation as the population and each province, autonomous region or municipality as sub-populations, and the stratified multi-stage systematic PPS cluster sampling scheme is used.
