§ Mrs. Gillan
To ask the Chancellor of the Exchequer how many people were employed in research science in each year since 1 January 1996. 
§ Ruth Kelly
The information requested falls within the responsibility of the National Statistician. I have asked him to reply.
Letter from Len Cook to Mrs. Cheryl Gillan, dated 21 October 2003:As National Statistician, I have been asked to reply to your recent question about people employed in research science since 1996. (132332)The attached table shows the number of people employed in four occupational groups that comprise workers in research science. This data is derived from the Labour Force Survey (LFS) 492W and is only available from Spring 2001, when the last major change to the Standard Occupational Classification (SOC2000) was implemented.Estimates for previous years have not been given as they are not available on a consistent basis. This is because the Standard Occupation Classification (SOC)2000 classification was introduced to the LFS in spring (March to May) 2001 and is not comparable with the SOC90 classification used in earlier periods.
