poverty vs inequality

The definition of poverty generally used in the UK, as in the rest of
the developed world, is set at 60% of median income. But these people
aren't poor in the same way as those 1.2 billion living on less than
$1.25 a day, obviously; they are poor in relation to the person who is
in the middle of the income distribution, with half the country above
them and half below. That median UK household income at the moment is
£23,200, which means the official threshold for poverty in the UK is
£13,920.
