LOS ANGELES – Hate crimes in Los Angeles County soared last year to their highest mark in five years even as overall crime dropped across the region, according to a report obtained by The Associated Press.

The annual report, to be published Thursday by the county's human relations commission, shows increases in several categories, with more hate crimes reported based on race, sexual orientation and religion.

In all, hate crimes increased 28 percent, to 763 last year from 594 in 2006. The most common hate crimes were those motivated by race, with 310 committed against black people and 125 against Latinos. However, crimes in which anti-immigrant slurs were used dropped slightly.

Civil rights attorney Connie Rice, who had not seen the report, said it is important to remember that hate crimes only form a tiny percentage of overall crime numbers. She said the increase is likely a reflection of economic times.

“When economic times gets tighter, hate crime violence goes up,” she said, adding that child abuse and domestic violence often increase for the same reason.

The numbers buck last year's overall crime trends, which saw a decrease of 6 percent in Los Angeles County and 5 percent in the city of Los Angeles, the report notes.

Gangs are a factor in many hate crimes. In all, 16 percent of hate crimes in 2007 were committed by gang members. According to the study, gang members committed 120 hate crimes last year, an increase of 14 percent from 2006.

The extent to which race is driving the area's gang crisis is a subject of ongoing debate. Sheriff Lee Baca has said he considers it a major factor, while Los Angeles police Chief William Bratton and other officials downplay suggestions of racial tension.

The report noted that friction between black and Latino residents continued to be a major factor driving hate crimes. There were 116 non-gang-related hate crimes committed by Latinos on blacks and 26 such crimes committed by blacks on Latinos.

The report found that white supremacist activity continued to be “surprisingly high,” with 131 hate crimes showing evidence of being carried out by white racists.

According to the U.S. Justice Department, for every hate crime that is reported to the police, up to 28 go unreported, often for fear of retaliation or concerns about talking to authorities.

The county's human relations commission has compiled an annual hate crimes report since 1980.
