Americans’ self-reported strict social distancing has declined nine percentage points in the past month. Currently, 38% say they are completely or mostly isolating themselves from people outside their household, which ties for the low in Gallup’s trend, measured in November…

That continues to be the case, as 34% of fully vaccinated adults are completely or mostly isolating, compared with 47% of partially vaccinated adults and 46% of those who are not yet vaccinated but plan to be. Adults who do not plan to get vaccinated remain the least likely to socially isolate, with 23% doing so.

The decline in strict social distancing this past month, then, appears to be driven mostly by the increase in U.S. vaccination rates. Thirty-two percent of U.S. adults reported having received at least one dose of a COVID-19 vaccine at the time of the March 15-21 survey, compared with 15% who were fully or partially vaccinated in February and 9% in January.
