The census of 28th May 1821 is less useful than those from 1841 onwards,
because names were not collected, except for the head of each household. The data was recorded in two tables, each starting at different
ends of a crude 'book', which consists of several loose sheets of paper
folded in half, and sewn together at the fold.
The tables do not have titles, and are transcribed as
TABLE A (occupation and gender data) and TABLE B
(age data).
As could almost be predicted, the numbers in
one table do not correspond with the other. Of slightly more
surprise, some names don't tally either. The anomalies that have
been spotted are listed below, so they are not mistaken for typos (of
course, there may also be typos) 

Richd. Pratt on TABLE A (house 4) appears to be Richd. Hale on TABLE B.

Jams. Rand on TABLE A (96) appears to be Jams. Anderson on TABLE B.
