Well, I think you phrased the question badly OP.
Are you asking how people will adjust their lifestyle/outgoings?
Because it’s self-evident that if someone loses a large chunk of their income they’re likely to struggle with essential outgoings such as mortgage, council tax, utilities, transport, childcare, insurance, etc, because a lot of people’s outgoings are based around their income.
Then we have food, clothes, savings, and luxuries, which can more easily be cut.
It depends what proportion of your income you spend on what, and how much slack you have in your budget.
If you’re like me and have a whacking great mortgage but are relatively frugal with food, for example, there is less scope to cut expenses. If you have a small mortgage or rent but spend loads on discretionary stuff it will be much easier.
Is that what you meant?
