Revisions information

A minor methodological revision has been made to the HBAI data series by the Department for Work and Pensions (DWP) to capture all income from child maintenance. This results in more income from child maintenance being included, in turn slightly increasing some household incomes and so tending to slightly reduce low income rates for families with children. The full back series (back to 1994/95) has been revised so that comparisons over time are on a consistent basis across the full time series. In terms of the impact of these revisions, in most cases the percentages of people in low income are unchanged rounded to the nearest percentage point.
