Eighteen hate crimes were reported in South Dakota previous year, with the bulk of victims targeted for their race or ethnicity or sexual orientation.
Human Rights Campaign Government Affairs Director David Stacy said in a statement that the numbers are more than likely incomplete: "The Trump administration, state and local jurisdictions must do more to prevent and respond to hate crimes".
The report was based on data voluntarily submitted by about 15,000 law enforcement agencies.
The specific data for both Iowa and Nebraska can be found to the side of this article.
In neighboring Minnesota, hate crimes rose from 109 to 119 during the same period. Muslims were targeted in 307 religion-based crimes, up 19 percent from 2015 and double the number in 2014.
According to the report, there were 6,063 single-bias incidents involving 7,509 victims of which approximately 59 percent were targeted because on racial, ethnic and/or ancestral bias; 21 percent because of religious bias, 17 percent on sexual orientation bias, 2 percent on gender identity bias, 1 percent on disability bias, and 0.5 percent on gender bias.
IN is one of five states without a hate crime law.
Stacy added that politicians must be more vigorous in addressing anti-LGBT bigotry and championing anti-discrimination policies, further noting that such strategies also "requires vigorous enforcement of hate crimes laws, which can deter and address violence motivated by bigotry". Over half of the religion-related offences were anti-Jewish, while a quarter were anti-Muslim, according to the data.
More than half the 4 229 racially motivated crimes were against black people, while 20% were against whites, the report shows.
The SPLC contends that the actual number of hate crimes may be much higher.
"No person should have to fear being violently attacked because of who they are, what they believe, or how they worship", Sessions said.
One such murder victim was transgender 16-year-old Kedarie Johnson, who was shot and killed in March of 2016 in what prosecutors have labeled a hate crime.
