1. The UK Census Pre and Post 1841

2. 1801 Information was collected on a parish basis and there were no details on households. Forms for recording the information were distributed to each parish where the overseers of the poor, 'substantial landholders' and local clergy all had a responsibility to collect specific types of data. Once the statistics had been collected, they were sworn before the local Justice of the Peace and eventually sent to the Home Office. The results were then collated and laid before Parliament.

3. 1801 They were to provide information on:  the number of inhabited and uninhabited houses in the parish  how many families occupied them  the number of people in the parish  their employment  numbers of baptisms, burials and marriages.

9. 1851 This was the first to record the full details of birth location for individuals and states the county and parish or town of birth as well. This was to give the rate and intensity of migration from rural to urban areas. The results confirmed there had been a significant shift from the countryside to the towns. The 1851 census was the first to record each person's marital status and relationship to the head of the household.

10. 1851 It also recorded details of disability - "blind, deaf or imbecile". Each individual's exact age was also recorded (to the nearest year) rather than rounding adult ages down to the nearest five years. Much greater detail was asked about people's occupations than in previous censuses. This enabled government analysis of occupations into "classes" and "sub-classes".

11. 1851 The Government also conducted a census of attendance at religious services on 30 March 1851, as part of the project. Date: 30 March 1831 Population: 17.9 million The Great Exhibition 1851

22. Census Jargon Buster Ditto, do, “ = the same as above. Abbreviated names = First and middle names may be shortened to ‘WM’ for William, ‘Chas’ for Charles, ‘Jas’ for James, Elizth’ for Elizabeth. Occupational abbreviations = ‘Ag Lab’ for agricultural labourer, ‘FS’ for female servant. ‘dom serv’ for domestic servant.

23. Census Jargon Buster Slash marks = double slash (//) indicate the end of one property. A single slash is a separate household within the same property. Crossings out = usually marks made when the information was being collated and does NOT mean anything was wrong.

24. Census search tips: 1. Enter as little information as necessary so you do not remove alternatives. Spelling or order of names may vary so be ready to try several. 2. Use variations and wildcards – Wildcards use an asterix to replace letters. For example Ann* will search for Ann, Anne, Annie; S*mpson will find Simpsonj and Sampson. Using ‘Soundex’ allows for spellings of a word that sound the same – Taylor might also offer Naylor, Gaylor and Tayler.

25. Census search tips: 3. Look for someone else in the family if the one you seek is not showing. This might at least bring up the household you are seeking even if your name is not present. 4. Find the censuses on each side, before and after to ensure you have as much clarity as possible. Check on local directories to find when the family might have moved house. 5. Try other websites to see if they pick up your ancestor better.
