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.
Orshansky was careful about what she was measuring. In her January 1965 article, she presented the poverty thresholds as a measure of income inadequacy, not income adequacy—”if it is not possible to state unequivocally ‘how much is enough,’ it should be possible to assert with confidence how much, on average, is too little.”
She was drawing a floor. A line below which families were clearly in crisis.
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). Childcare didn’t really exist as a market—mothers stayed home, family helped, or neighbors (who likely had someone home) watched each other’s kids. Cars were affordable, if prone to breakdowns. With few luxury frills, the neighborhood kids in vo-tech could fix most problems when they did. College tuition could be covered with a summer job. Retirement meant a pension income, not a pile of 401(k) assets you had to fund yourself.
Orshansky’s food-times-three formula was crude, but as a crisis threshold—a measure of “too little”—it roughly corresponded to reality. A family spending one-third of its income on food would spend the other two-thirds on everything else, and those proportions more or less worked. Below that line, you were in genuine crisis. Above it, you had a fighting chance.
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.
The labor model shifted. A second income became mandatory to maintain the standard of living that one income formerly provided. But a second income meant childcare became mandatory, which meant two cars became mandatory. Or maybe you’d simply be “asking for a lot generationally speaking” because living near your parents helps to defray those childcare costs.
The composition of household spending transformed completely. 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.
If you keep Orshansky’s logic—if you maintain her principle that poverty could be defined by the inverse of food’s budget share—but update the food share to reflect today’s reality, the multiplier is no longer three.
It becomes sixteen.
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.
And remember: Orshansky was only trying to define “too little.” She was identifying crisis, not sufficiency. If the crisis threshold—the floor below which families cannot function—is honestly updated to current spending patterns, it lands at $140,000.
What does that tell you about the $31,200 line we still use?
It tells you we are measuring starvation.
