Relative poverty is a term used on the news to mean people who have less money than those living around them. This term is generally used when talking, for example about “UK child poverty”. (Politicians even argue about whether such differences in wealth are a good or bad thing.)
Absolute poverty is different. Some people are much poorer. For them, a whole week’s income is less than the amount someone in the UK, on the legal minimum wage, earns in an hour (£5.93).
