Do they ask different questions in England, Wales, Scotland, and Northern Ireland?
The majority of the questions are the same but in the 2001 Census an additional question on religion was asked in England, Wales and Northern Ireland and a question on Welsh, Gaelic and Irish was asked in Wales, Scotland and Northern Ireland respectively. Extra information was also collected in Scotland on the address of the place of study and means of travel to the place of study. For household accommodation, there was a question in Scotland on whether rented accommodation was furnished or unfurnished and in Northern Ireland, the number of floor levels in the accommodation was asked. England was the only part of the United Kingdom to ask a question on professional qualifications. More information can be found in the overview units on the census questionnaire and change over time.
