It found that nearly a third of those polled have “avoided publicly wearing, carrying or displaying things that might help people identify them as Jews.”
And a quarter of respondents said they avoid places, events or situations out of concern for their safety or comfort.
Those horrific incidents were among many other recent instances of anti-Semitism.
The AJC survey suggests Jewish Americans are feeling the impact of these attacks. Nearly nine out of 10 say anti-Semitism is a current problem in the US, and 72% say they do not approve of the Trump administration’s handling of the threat, according to the survey.
“American Jews could not be clearer about the reality of anti-Semitism in the U.S.,” said AJC CEO David Harris. “This hatred is real, comes from multiple sources, and is growing. It needs to be taken seriously and dealt with in a sustained, multi-pronged response.”
The survey had a margin of error of plus or minus 4.2 percentage points.
CORRECTION: This story has been updated to reflect the correct margin of error.
