The New York Times obtained an advanced copy of a study by researchers at Cal State San Berdoo on the prevalence of hate crimes in the United States.

While the most current hate crime statistics from the F.B.I. are not expected until November, new data from researchers at California State University, San Bernardino, found that hate crimes against American Muslims were up 78 percent over the course of 2015. Attacks on those perceived as Arab rose even more sharply.
