It's relative poverty though, nothing like absolute poverty where there is no shelter and little food like Africa etc.
The CPAG states 35% of children classed as being in relative poverty are in families of three or more children.
65% of children only have one parent working (weirdly it doesn't state the amount in households where no one works).
They also class not having a holiday as being in poverty, which is simply outrageous. Since when did that kind of luxury and non essential become an indicator of poverty?
People don't help themselves. It's simple enough to understand that the more children the less money to go round and not earning a salary means less for the household.
