Help! I am putting together a presentation and lesson around the Freedom Summer of 1962 (voter registration, Freedom Rides, etc.). I am using the GeoInquiries as a template and would like to have some data layers that show the demographics of the southern states in the 1960s so that teachers and students can investigate population trends and differences. I can't seem to locate anything in ArcGIS Online and the Living Atlas. Any ideas on where I might find this information or people I can ask would be great. Thanks so much!
