Put in an area and see for yourself. In general, yes this calculator is closer to what you're describing. For example, Skamania County, a pretty rural county of Washington state with a very low population of 12,000 people, still has a "required living wage" for 1 breadwinner + 1 homemaker + 3 children of $104,292 per year: https://livingwage.mit.edu/counties/53059That feels pretty close to accurate.
