Link to source: Persistent poverty in the UK and EU: 2015
Being in persistent poverty is defined by The Office for National Statistics as when someone is currently in poverty and has been in poverty for at least two of the three preceding years.
Some groups are more likely to be in persistent poverty than others. In particular lone parents are much more likely to experience persistent poverty than other groups, as are single people without children. Couples with children and households with two or more adults but no children are much less likely to be in persistent poverty.
