This dataset provides 2011 Census estimates that classify usual residents in households in England and Wales who are aged 16 and over by long-term health problem, provision of unpaid care, and by sex. The estimates are as at census day, 27 March 2011.
This information helps to develop and monitor policy on the delivery of health care, the reduction of health inequalities and the assessment of progress towards improving the general health of the population.

In order to protect against disclosure of personal information from the 2011 Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.

More details on the ONS Census disclosure control strategy may be found on the Statistical Disclosure Control page on the ONS web site.
