This review of Census Bulletin No. J1 from the 1961 Census of Pakistan is fifth in a series2 of review articles on the census publications prepared by or under the auspices of the Demographic Section of the Pakistan Institute of Development Economics. The Bulletin is an interim report on the economic characteristics of the population of Pakistan. It was published in the second week of March, and released in the third week of May 1963.

There is a two-page introduction giving the method and questions through which the data on economic characteristics were obtained. It also promises more data on economic aspects in the main census reports still to be issued.
