Income is INSEE's median standard of living: a household's disposable income after taxes and benefits, divided by its consumption units, so one income is a single adult's. It is published about two years late, so today's price is set against the latest year. The HCSF caps the payment, insurance included, at 35% of income for most new loans, and banks may lend less.
