Tribal transportation planners are invited to a TRB webinar on Thursday, October 17, 2019, from 1:00 PM to 2:30 PM ET. This webinar will provide information about accurately counting tribal communities in the American Community Survey and the 2020 census. The American Indian/Alaska Native (AI/AN) census has a significant role in several federal fund distribution formulas, including the Tribal Transportation Program (TTP) administered by the Federal Highway Administration and Bureau of Indian Affairs. The TTP’s reliance on an Indian Housing Block Grant regulation for determining AI/AN population for each federally recognized tribe has seen fluctuations based on 2016 rule changes. The United States is also actively preparing for the 2020 census.
