Comments:

1 Parishes were often divided between different Baronies, and Baronies were sometimes divided between different Counties, but this reconstruction always lists the totals for whole Parishes or Baronies. The original table also sometimes lists separate counts for 'Towns' and the remainders of Parishes, but here again we list only Parish totals.
2 The original table lists areas in Acres, Rods and Perches, but they have been converted here into decimal acres.
3 The original table also includes Poor Law and General Valuations for each area.

This website does not try to provide an exact replica of the original printed census tables, which often had thousands of rows and far more columns than will fit on our web pages. Instead, we let you drill down from national totals to the most detailed data available. The column headings are those that appeared in the original printed report. The numbers presented here, which are the same ones we use to create statistical maps and graphs, come from the census table and have usually been carefully checked.

The system can only hold statistics for units listed in our administrative gazetteer, so some rows from the original table may be missing. Sometimes big low-level units, like urban parishes, were divided between more than one higher-level units, like Registration sub-Districts. This is why some pages will give a higher figure for a lower-level unit: it covers the whole of the lower-level unit, not just the part within the current higher-level unit.
