There has been a census in England and Wales every ten years since 1801, excluding 1941.  Censuses taken before 1841, however, do not contain individual names of residents.

Each head-of-household was given a form to complete, recording who was in their household during the period Sunday night to Monday morning.  On Monday morning, census enumerators collected the household schedules.  If the forms were not completed properly, the enumerator was supposed to ask for missing information.  Not every enumerator was careful or consistent in his work.

Once the forms were collected, enumerators transferred the information into a book, which was transmitted to authorities responsible for specific jurisdictions.  Original forms were not kept.  The census documents available today are microfilmed copies of the enumerator's books maintained at the UK National Archives in Kew, Surrey.

The census date for 1841 was Sunday night, June 6th.

No relationships are given in this census, and the only birth location question was "Born in this county" (yes or no).  In the transcription below, births are shown as either Glamorgan or Other.

Individuals under 15 had their exact ages given, but ages 15 and above should have been rounded down to the nearest 5-year point.  Remember people often said they were in their NNth year, which meant they had passed their previous birthday.  In the case of a person who said (s)he was "in my 60th year," the age may be recorded as 60 when it should actually have been recorded as 55.
