What these numbers mean
The margin is net income minus required costs. The margin is not an inflation rate and does not replace the CPI. A negative margin means the required monthly costs are larger than net income after taxes.
The renter column uses current asking rent. The owner columns use housing costs for homeowners: with a mortgage, with the home paid off, and a blend of the two. The basket is a market-price standard: current asking rent and unsubsidized average marketplace premiums. It can run above what a settled household pays, and the methodology states this.
