According to recent data from NYC (pretty expensive example but still) the rent-to-income ratio (median yearly rent / median yearly income) is ~55% citywide but up to 80% in the Bronx (which has the lowest income of the 5 boroughs)
Edit for clarity: the median income number is also per “household” (I’m assuming per apartment in this case), so it accounts for multiple working people living together
