The information requested falls within the responsibility of the UK Statistics Authority. I have asked the authority to reply.
Letter from Stephen Penneck, dated March 2010:
As Director General for the Office for National Statistics, I have been asked to reply to your Parliamentary Question asking for the recent estimate of the proportion of people employed in social care who are women. (320654)
For the period October-December 2009 it was estimated that 1.4 million women were employed in social care in the UK, the proportion of women employed in social care is 80.0 percent.
These estimates are derived from the Labour Force Survey (LFS) and are not seasonally adjusted. The social care estimate was derived using the Standard Industrial Classification (SIC2007) codes: 87. Residential care activities and 88. Social work activities without accommodation.
As with any sample survey, the estimates provided are subject to a margin of uncertainty.
