Census 1991 - Output Areas

Alternative title(s)

1991 OA's

Abstract

NRS first created Output Areas (OAs) for the 1991 Census to allow comparability with small area statistics output from 1971 and 1981. NRS used postcodes to plan 1981 Census enumeration districts and 1991 postcode based OA generally fell within 1981 ED. 1971 small area statistics were retabulated for 1981 Enumeration Districts thus provided an degree on continuity over 3 censuses. OAs are the lowest level for which small area statistics for the 1991 Census are available. For confidentiality purposes each OA has at least 16 households and 50 usual residents. There are 38,254 Census 1991 OAs in Scotland. Of the 38,254 1991 output areas, 38,098 have polygons, the remaining 156 are special output areas. Revisions and Corrections Correction to 1991 Output Area boundaries An anomaly was discovered in the 1991 Output Area boundaries where the boundaries for Output Areas 6341DX13 and 6341DX16B were not following the postcodes that they were built up from.

Lineage

NRS first created Output Areas (OAs) for the 1991 Census to allow comparability with small area statistics output from 1971 and 1981. NRS used postcodes to plan 1981 Census enumeration districts and 1991 postcode based OA generally fell within 1981 ED. 1971 small area statistics were retabulated for 1981 Enumeration Districts thus provided an degree on continuity over 3 censuses. OAs are the lowest level for which small area statistics for the 1991 Census are available. For confidentiality purposes each OA has at least 16 households and 50 usual residents. There are 38,254 Census 1991 OAs in Scotland. Of the 38,254 1991 output areas, 38,098 have polygons, the remaining 156 are special output areas. For special enumeration districts (usually large communal establishments) output areas were created only if the number of usual residents met the confidentiality threshold. In such cases, household data are not provided. These special output areas do not have mapped boundaries; their position is identified by a single grid reference. Revisions and Corrections Correction to 1991 Output Area boundaries An anomaly was discovered in the 1991 Output Area boundaries where the boundaries for Output Areas 6341DX13 and 6341DX16B were not following the postcodes that they were built up from.
