Gender profiling in traffic stops: When compared with men, women were 23 percent less likely to be ticketed, 55 percent less likely to be arrested and 76 percent less likely to be searched when stopped by police.

Some of his most significant findings include:

• When compared with men, women were 23 percent less likely to be ticketed, 55 percent less likely to be arrested and 76 percent less likely to be searched when stopped by police. Women were more likely to only receive a warning or have no outcome when stopped by police during a traffic stop.

• Black and Hispanic drivers were significantly more likely to be searched, ticketed and arrested than white drivers when stopped by police. For example, black drivers were more than twice as likely to be searched or arrested when compared with white drivers. Hispanic drivers were almost three times as likely to be searched when compared with white drivers.

By combining data dealing with race and gender, Briggs found the differences between men and women do not hold up for all races. Out of all racial and ethnic categories of male and female drivers, white women were most likely to receive a perceived benefit in a traffic stop, such as receiving only a warning or no outcome at all. But the same is not true for black and Hispanic women, who were just as likely as white men to be ticketed, arrested or searched instead of receiving a warning or no outcome.

Black and Hispanic men were the most likely to be ticketed, arrested or searched during a traffic stop. Black men were 2.5 times as likely as white men to be arrested and twice as likely to be searched. Hispanic men were 1.5 times as likely as white men to receive a ticket and more than three times as likely to be searched.

"We can't make sense of racial differences without also considering sex and gender," Briggs said. "We have to look at sex and gender at the same time as race and ethnicity because they're connected in important ways. What I found in the case of traffic stops was that racial differences are deeply gendered as well. This connection should be a part of the larger racial profiling discussion."
