I agree with you that the calculation to determine 'poverty' doesn't quite make sense.
Mathematically speaking, if the average income is, say, £25,000 and 60% is deemed the level at which poverty begins, then that's £15,000 of income (from whatever source). That's too simplistic for a gauge of poverty. A family with one earner, and one child might be able to make do with that income.
A family with four kids will not.
It doesn't mean that both families are living in poverty.
FYI - I have to get a calculator out to work out what 60% of £25,000 is...
...quite shameful really.
