The Southern Poverty Law Center created a hate map of its own to represent the geography of active hate groups per state in the United States for the year 2012. Its map shows a larger display of active groups in the western U.S., especially California, than Stephens' map.
"If you look at the hate groups in our map, it roughly follows population. We can't adjust per capita," Mark Potok, senior fellow at the Southern Poverty Law Center, told ABC News.
Speaking of Stephen's Twitter research, Potok said he didn't find her map all that surprising. "You find some anti-black comments in the Deep South. It seems there is a historical legacy that is still with us."
Stephens and her student researchers plan to refine the "Geography of Hate" further through deeper analysis of demographic data, including income, education, diversity and proximity to organized hate groups.
"This project will continue," she said.
