A Mechanical Accounting of the Family Incidence and Poverty Leverage of U.S. State Minimum-Wage Increases
This noncausal study analyzes U.S. state minimum-wage increases from 2006 to 2019 and finds that while they generate significant resources for workers in poor families, the resulting poverty reduction is minimal, achieving only 1.0% of the theoretical benchmark for reducing the poverty headcount.

Every year, millions of Americans rely on a minimum wage, a legal floor that sets the lowest amount an employer can pay for an hour of work. This rule is designed to protect workers, but it operates at the level of the individual job, not the household. In contrast, the official measure of poverty looks at a family's total cash income over a year and compares it to a specific threshold that changes based on family size. These two systems do not always line up. A person earning just above the minimum wage might belong to a family that is comfortably well-off, while a family struggling to make ends meet might have no one working a job covered by the minimum wage. Even when a low-wage worker is part of a poor family, a small raise might not be enough to push that family's total income over the poverty line. Understanding exactly how these two worlds intersect is crucial for knowing whether raising the minimum wage actually helps the people who need it most.
A researcher at Texas Tech University set out to map this connection without guessing how people might change their behavior in response to a new law. Instead of trying to predict if a worker would lose their job or if a family would have more children, the study took a "mechanical accounting" approach. This means the researcher took a snapshot of the past, holding everything constant: the number of hours people worked, their non-wage income, and the exact list of people living in each family. Using data from 2006 to 2019, the study traced exactly how much extra money would have flowed to families if state minimum wages had increased as they did in history, assuming nothing else changed. The goal was to see how much of that extra money actually reached poor families and how much of it was enough to lift them out of poverty.
The results reveal a significant gap between the workers who get a raise and the families who need help. When looking at workers whose wages fell into the specific range affected by state minimum wage increases, only about 14 percent of them were linked to families classified as poor. This means that the vast majority of the people receiving these wage bumps were supporting families that were already above the poverty line. Furthermore, when the researcher calculated the total amount of extra money predicted to be generated by these wage hikes, only about 11.6 percent of that money ended up in the pockets of poor families. The rest went to families that were not struggling financially. This mismatch happens because low-wage workers are spread widely across the entire income distribution, not just concentrated in poor households.
The study then asked a harder question: for the money that did reach poor families, was it enough to make a difference? The researcher compared the actual outcome of these wage increases against a theoretical "best-case scenario." In this best-case scenario, the exact same amount of money was available, but it was distributed perfectly to close the specific gaps keeping families in poverty. The comparison showed that the real-world minimum wage increases achieved only about 1 percent of the possible reduction in the number of families living in poverty. In other words, if the goal was simply to move families over the poverty line, the minimum wage was a very blunt instrument. However, the study found a slightly different story when looking at the depth of poverty. When measuring how far below the poverty line families were, the wage increases achieved about 7 percent of the possible improvement. This suggests that while the raises rarely lifted families all the way out of poverty, they did help narrow the financial gap for those who remained poor.
The research also explored a broader definition of who might benefit, including workers whose wages were below the official minimum due to various legal exceptions or reporting quirks. Even with this wider net, the study found that the vast majority of the predicted resources—nearly 89 percent—came from wage gaps that existed before any state policy changes were implemented. This indicates that much of the potential benefit comes from fixing existing underpayments or addressing complex work situations rather than from new, state-mandated raises. Ultimately, the study concludes that while minimum wage laws are a powerful tool for raising earnings, they are not a targeted solution for poverty. They reach many people who do not need the help and often provide too little money to the families who do. The findings do not say the policy is bad, but they clarify that its power to directly eliminate poverty is mechanically limited by the fact that it pays workers, not families, and that the workers it pays are not always the ones living in poverty.
