In the course of validating the households below average income (HBAI) statistics, the Department for Work and Pensions (DWP) and Department for Social Development (Northern Ireland) statisticians identified an inconsistency in the way Northern Ireland rates were being calculated over time. As a result the proportion of population groups in low-income households has been overestimated. The effect on UK low-income statistics is likely to be very small (of the order of 0.1 percentage points lower) while the effect on Northern Ireland low-income statistics is likely to be larger (of the order of 1 or 2 percentage points lower).
