Poverty in the United Kingdom refers to the portion of the population of the United Kingdom that are considered to be in poverty under some measures of poverty. Data based on incomes published in 2016 by the Department for Work and Pensions (DWP) show that, after housing costs have been taken into consideration, the number of people living in the UK in relative poverty to be 13.44m (21% of the population). In 2015, a report by Institute for Fiscal Studies reported that 21.6% of Britons were in relative poverty. The report showed that there had been a fall in poverty in the first few years of the 21st century, but the rate of poverty remained broadly flat in the decade after 2004/5.
