Bach domain for which separate estimates were\nrequired was made a separate stratum. As such each sector\n(Urban, Rural, Estate) within each district was considered as a\nseparate stratum.\n\nSample Size\nIn this design the first stage units (FSU) were the census\nblocks prepared at the 1981 Census of Population and the\nsecond stage units (SSU) were the housing units. It was decided\nto select 10 housing units from each selected census block.\nThus, a first stage sample of about 2,500 census blocks have to\nbe selected from the entire island.\n\nSample Allocation and Method of Selection\nThe allocation of 2,500 census blocks to each district\nwas made proportional. to the square root of the population\u00b7 ( as\nat 1981 Census ) in that district. These values have been rounded\nto multiples of twelve. ( Refer page 5 of the final report attached in the external resources section)\nIt was decided to over sample the urban sector in each district\nin comparison to the rural and estate sectors with the objective\nof allocating roughly by one-third of the total sample.\nAllocation between the rural and estate sectors in each\ndistrict was proportional to 1981 population. Within each\nstratum, the assigned number of FSU's were selected with probability\nproportionate to size (using the Census or adjusted housing\nunit counts ) with replacement.\nThe lists of census units prepared for the Census of Population\nand Housing 1981, of each selected block were updated to include\nnew \u00b7housing units and to exclude ones which are no longer\nin existence. This updating operation was also staggered over a\nperiod of twelve months starting from  May 1990  to April 1991.\nFor each FSU, updating was done about one month prior to the\nscheduled interviewing.","sampling_deviation":"Non-Response\nOf a sample of 25080 housing units selected only 19,401\nhouseholds were covered in the survey.
