Be fair if they're at 65 and don't own their home they are never ever going to be above the poverty threshold. Never.Worth noting that 'disposable income' is defined as earnings after tax.
65+ (£32k) has a little less than 25-34 (£34k) age group, but more than 16-24 (£26k)
Of course, around 75% of 65+ own their homes outright (no mortgage), so pay no housing costs.
Clearly, as a group, after housing is taken into account, they will have a lot more 'disposable income'.
