The national 1 July, mid-year population estimates (usually based on past national censuses) supplied in these tables are given in thousands. The retrospective figures use the present-day names and world political division: for example, the table gives data for each of the 15 republics of the former Soviet Union, as if they had already been independent in 1950.

In practice, the sample size used in a study is usually determined based on the cost, time, or convenience of collecting the data, and the need for it to offer sufficient statistical power. In complex studies ...

In statistics, the method of moments is a method of estimation of population parameters.The same principle is used to derive higher moments like skewness and kurtosis. It starts by expressing the population moments (i.e., the expected values of powers of the random variable under consideration) as functions of the parameters of interest.
Between the national censuses, 1% National Population Sample Surveys were taken in 1987, 1995, and 2005; 0.1% National Population Sample Surveys have been taken annually since 2000. [64] National agricultural, economic, and industrial censuses are also taken on a regular basis. The first economic census was taken in 2004 and the second 2008. [65]
