“According to the U.S. Census Bureau’s supplemental poverty measure, the stimulus payments moved 11.7 million people out of poverty in 2020 — a drop in the poverty rate from 11.8 to 9.1 percent. And the 2021 poverty rate was estimated to fall even further to 7.7 percent, per a July 2021 report from the Urban Institute. We don’t know yet whether this came to fruition, but Laura Wheaton, a senior fellow at the Urban Institute and one of the analysts behind the 2021 numbers, told us that it was clear from their analysis that the stimulus checks were driving a dramatic decline in poverty.
More broadly, the stimulus checks also cushioned workers during one of the worst economic crises in modern history, which likely helped the economy bounce back in record time. In April 2020, when Americans were receiving the first round of checks — up to $1,200 with the CARES Act — the unemployment rate was at a disastrous 14.7 percent. But two years later, it’s almost returned to its pre-pandemic levels, with many job openings. “I hope we don’t forget how awesome it was that we supported people so well, and that we recovered as quickly as we did,” said Tara Sinclair, a professor of economics at George Washington University.
However, there is also evidence that the stimulus, especially the last round, likely stoked higher and higher prices for the very people it was intended to help. Though global supply chain issues (and, more recently, the war in Ukraine) have been significant drivers of inflation, the divergence between U.S. and European inflation suggests there’s more to it than that. In fact, a recent analysis from researchers at the Federal Reserve Bank of San Francisco found that the stimulus may have raised U.S. inflation by about 3 percentage points by the end of 2021.”
