Variable: SPIKEIND
Table: ME01x
Short description: Area identifier change indicator. 2001.
Full description: Some LS member households were moved from one location to another in the final stages of 2001 Census data processing. This was partly ONC adjustment of 'spikes' or to do with revisions to postcodes (enumpc0 + revisions = fpc0). LS members should have been immune but about 270 cases were affected. Variables affected: all at ward or below, including output areas and grid references. Variables not affected: county district level area identifiers and above.
Coding notes: Code 2 for 'initial extract only' did not have a final extract entry to allow coding on this variable.
