More Americans Say They’re in a Cognitive Fog, Adults in their 20s, 30s and 40s are driving the trend. Researchers point to long Covid as a major cause.
In its monthly Current Population Survey, the census asks a sample of Americans whether they have serious problems with their memory and concentration. It defines them as disabled if they answer yes to that question or one of five others about limitations on their daily activities. The questions are unrelated to disability applications, so respondents don’t have a financial incentive to answer one way or another.
At the start of 2020, the survey estimated there were fewer than 15 million Americans ages 18 to 64 with any kind of disability. That rose to about 16.5 million by September 2023.
Richard Deitz, an economist at the Federal Reserve Bank of New York, analyzed the data and attributed much of the increase to long Covid. “These numbers don’t do this — they don’t just start suddenly increasing sharply like this,” he said.
