Up to 1961 almost all population totals, from parishes up to national totals, are computed from the census parish tables; details are in 'Source Info View'. We very carefully checked these tables both for internal consistency and against district-level totals in age structure tables. This work both eliminated almost all computerisation errors and showed that the original tables had been carefully checked before publication. However, adding the data to our system meant matching up unit names in the census table with names in our core gazetteer — the information on our 'Relationships' pages. Because of variations in naming, not all of the most detailed data are currently linked in. This usually results in a simple gap in the population time series, but very occasionally the original tables gave separate population figures for the parts of a parish. If some but not all of the names match there will be an erroneously low population total. We are working to eliminate these.
