"Figure 10: Percentage differences between ABIS's and ETB's 10th percentile, median and 90th percentile gross equivalised household income figures","" "By region, England and Wales, tax year ending 2016","" "","" "Notes","ETB Notes:
1\. Our [Effects of taxes and benefits on UK household income bulletin](https://www.ons.gov.uk/peoplepopulationandcommunity/personalandhouseholdfinances/incomeandwealth/bulletins/theeffectsoftaxesandbenefitsonhouseholdincome/previousReleases) is based on the Living Costs and Food Survey (LCF) of around 5,000 UK households.
2\. The ETB data is equivalised, gross household income.
3\. The ETB data has been adjusted to remove income from investment and Personal Independence Payment to align more closely with the coverage of the ABIS income measure. 
4\. The ETB figures are not SPI adjusted. ETB has not previously published SPI adjusted income deciles by region. The ETB team aim to develop SPI adjusted versions of these estimates in the future.
5\. A three-year average is presented of ETB data from tax years ending 2015, 2016 and 2017, with annual incomes in 2015 to 2016 prices.
6\. The ETB data presented here are not comparable with the published ETB National Statistics and cannot be used for independent ETB analysis. The ETB figures presented here are specific to this partial income concept, developed to correspond more closely with the ABIS.
ABIS Notes:
1\. The ABIS data is equivalised, gross household income.
2\. These admin-based income statistics are experimental and should not be used as an indicator of poverty or living standards.  Rather they are published to demonstrate the feasibility of producing income statistics using a different methodology to that currently used in the production of income statistics.
3\. Data Source: Pay As You Earn (PAYE) employment and pension data, self-assessment self-employed and partnership data, child benefit data and tax credits data from HM Revenue and Customs and benefits data from the Department for Work and Pensions. As these Experimental Statistics are limited to these data sources, some components of income are not included, for example, self-employment and investment income.
4\. Only individuals and households present on the population base (Admin Based Population Estimate (ABPE) V3) were included in these statistics.
