Volume 476: debated on Monday 19 May 2008

To ask the Secretary of State for Work and Pensions what estimate he has made of the number of people in the UK with an income of (a) £100,000 or more and (b) £12,000 or less gross per annum in (i) 2002 and (ii) 2007. (203227)

[holding answer 1 May 2008]: The available information is shown in the following tables. Individual gross income has been used.

Table 1: Number of UK taxpayers (million) with gross annual incomes of £100,000 or more





Source: Survey of Personal Incomes (SPI) 2002-03 and 2005-06, HMRC

Table 2: Number of people (million) in the UK with gross annual incomes of £12,000 or less in 2002-03 and 2005-06





Notes: 1. Figures in the tables compare reported gross annual incomes, except for the estimate for 2007-08 in Table 1 which is based on projected incomes from the 2005-06 SPI. 2. The figures in Table 2 for 2005-06 are the latest available data. 3. SPI data are published by HMRC and FRS data are published by DWP. It has been assessed that the SPI is the most reliable data source for annual incomes of over £100,000, while the FRS is the best source for incomes below £12,000. 4. The information shown is for the UK. The SPI figure in Table 1 is given for all UK taxpayers regardless of place of residence, not just those in the UK. 5. Figures are given in millions rounded to the nearest 100,000 persons. 6. The FRS estimates are sample counts, which have been adjusted for non-response using multipurpose grossing factors that, in the case of the FRS, control for tenure, Council Tax band and a number of other variables. Estimates are subject to both sampling error and to variability in non-response. The income measure used is annual gross individual income. 7. The SPI is a sample survey of information held by HMRC tax offices on persons who could be liable to UK tax. It is carried out annually and covers the income assessable for tax in each tax year. As with all sample surveys, estimates from the SPI have a sampling error attached to them. Source: Family Resources Survey (FRS)2002-03 and 2005-06, DWP.
