It is found that almost one-third of the respondents "avoided wearing, wearing or displaying things publicly that could help people identify them as Jewish."
And a quarter said they were avoiding places, events or situations that are not concerned with their safety or comfort.
These horrific incidents were among many other cases of anti-Semitism.
the AJC study shows that Jewish Americans feel the impact of these attacks totaling 1,879 attacks against Jews and Jewish institutions nationwide. Nearly nine in 10 say anti-Semitism is a topical issue in the US, and 72% say they disapprove of the Trump administration's handling of the threat, according to the survey.
"American Jews could not be more clear about the reality of anti-Semitism in the United States," said AJC Executive Director David Harris. "This hatred is real, comes from many sources and is growing. It has to be taken seriously and work with a consistent, multifaceted response. "
The study had a margin of error of plus or minus 4.2%.
