I have been asked to reply.
The following table shows the median and mean gross household income for the household types requested.
Gross unequivalised household income Household type Median Mean Two working age adults and two children 770 1,034 One working age adult and two children 329 384 One working age adult and one child 290 354 Two working age adults and four children 619 n/a Two working age adults, either with or without children 740 939 One working age adult, either with or without children 330 429 n/a = Not available Notes: These statistics are based on Households Below Average Income (HBAI), sourced from the Family Resources Survey. Small differences should be treated with caution as these will be affected by sampling error and variability in non-response. The reference period for HBAI figures is single financial years. The income measure used here is unequivalised, i.e. it has not been adjusted for household size and composition. This is because the groups requested are based on household size and composition, and in this specific instance, equivalisation would cloud the comparison between household types. This means that the statistics presented are on a different basis to those in the HBAI publication. Median household incomes are less affected by outliers, and are therefore generally more commonly used in analysis of incomes. In particular, the sample size for households containing two working age adults and four children is relatively small, so estimates for this group are subject to a higher degree of sampling error than the other groups presented. This particularly affects the mean, where no robust estimate can be produced. Gross incomes have been presented. The HBAI publication looks at net disposable incomes Before and After Housing Costs. While the statistics cover individuals who are of working age, not all individuals will be working. Source: Households Below Average Income, 2007-08
