c. 4), long title An Act for taking the Census for Great Britain in the year one thousand nine hundred and one, was an Act of Parliament of the Parliament of the United Kingdom, given the Royal Assent on 27 March 1900 and since repealed.

The information to be recorded was broadly the same as in previous years - the name, sex, age, occupation, marital status, birthplace, and nationality where appropriate, along with the relation to the head of the family, for every person staying in that house on the night of the census day.

Information was, as usual, also to be gathered from aboard ship, as well as in prisons, hospitals, workhouses, asylums, etc.

In Scotland, the number of rooms in each dwelling which possessed windows, inclusive of the kitchen, was to be recorded.

In Wales and Monmouth each person above the age of three was to state if they spoke Welsh or English, or a mixture of both.
