There are no reliable data on the number or rate of hate crimes in the United States, according to the investigative news nonprofit ProPublica. The organization has collected several dozen self-reports of alleged incidents of hate and bias in Wisconsin — most of them unconfirmed — since November 2016 when it began soliciting tips as part of its Documenting Hate project. The Wisconsin Center for Investigative Journalism is among more than 100 news outlets and other groups participating in the project.
