According to the Anti-Defamation League, New York saw a 26% increase in these incidents last year, with a 106% increase in assaults in particular.
New Jersey saw 345 incidents last year in a 73% increase over the year before.
The ADL says the incidents are not linked to one particular political ideology.
"I think the charged environment contributes to it, I think big concerns about social and economic challenges that seem to be going unanswered is part of it," said Jonathan Greenblatt, CEO, Anti-Defamation League. "Social media amplifies these issues to a great degree as well."
The ADL numbers are the highest in the 40-year history of tracking these incidents.
The organization is already concerned about this year, with a rise in incidents linked to conspiracy theories about the coronavirus.
