The-demand for -extensive and reliable demographic data is growing in most countries of "the world, and especially those engaged in the task of planning for economic and social development feel this need keenly. The population censuses have been one of the chief, sources of information on- a national basis, but census programmes even in the more advanced countries are now unable to meet all the requirements. Censuses are expensive and- if all the needs were to be me lt through the traditional -census method of complete enumeration and wholesale tabulation of the data -collected, the cost, time and organization required would place a serious, strain on the resources normally available for census-taking. The use of sampling methods in population censuses has of late afforded the opportunity of getting much additional information which would otherwise not be available.
