Calculating income

The regulations may specify how income will be calculated. For example, if an applicant has a partner or spouse who lives with them, the amount may be based on their combined income. This is common for income-tested benefits. It helps ensure the benefit goes only to those who need it most. (The incomes of other members of the household, such as parents, adult children, or siblings, are not usually used in these calculations.)

I guess divorce may become more common. It also looks like people from marginalized communities may get more money. I don’t know what race has to do with being disabled? Cost of living is the same for everyone
