This week, while trying to understand why the American middle class feels poorer each year despite healthy GDP growth and low unemployment, I came across a sentence buried in a research paper:
“The U.S. poverty line is calculated as three times the cost of a minimum food diet in 1963, adjusted for inflation.”
The formula was developed by Mollie Orshansky, an economist at the Social Security Administration. In 1963, she observed that families spent roughly one-third of their income on groceries. Since pricing data was hard to come by for many items, e.g. housing, if you could calculate a minimum adequate food budget at the grocery store, you could multiply by three and establish a poverty line.
For 1963, that floor made sense. Housing was relatively cheap. A family could rent a decent apartment or buy a home on a single income, as we’ve discussed. Healthcare was provided by employers and cost relatively little (Blue Cross coverage averaged $10/month).
But everything changed between 1963 and 2024.
Housing costs exploded. Healthcare became the largest household expense for many families. Employer coverage shrank while deductibles grew. Childcare became a market, and that market became ruinously expensive. College went from affordable to crippling. Transportation costs rose as cities sprawled and public transit withered under government neglect.
In 2024, food-at-home is no longer 33% of household spending. For most families, it’s 5 to 7 percent.
Housing now consumes 35 to 45 percent. Healthcare takes 15 to 25 percent. Childcare, for families with young children, can eat 20 to 40 percent.
Which means if you measured income inadequacy today the way Orshansky measured it in 1963, the threshold for a family of four wouldn’t be $31,200.
It would be somewhere between $130,000 and $150,000.
The official poverty line for a family of four in 2024 is $31,200. The median household income is roughly $80,000. We have been told, implicitly, that a family earning $80,000 is doing fine—safely above poverty, solidly middle class, perhaps comfortable.
But if Orshansky’s crisis threshold were calculated today using her own methodology, that $80,000 family would be living in deep poverty.
