tl;dr The infographic misrepresents its own data source. The following is how I proved this to myself in roughly stream-of-consciousness how I followed what was happening. I had questions about how this is averaged... I know that in Seattle schools start after 8:50am. But it has Washington as a dark orange. But given that Washington's 2 most populous urban areas (Encompassing Spokane, Seattle, and Tacoma) both start their schools after 8:40am, I'm wonder how this has Washington as averaging 7:56am to 8:05am. Additionally, the more I check the counties in Washington, the more I doubt that this is correct. School start times seem to be consistently after 8:30am, which would align with what I know about the state. So I looked at their source: https://nces.ed.gov/surveys/ntps/tables/ntps1718_table_05_s1s.asp https://nces.ed.gov/surveys/ntps/tables/ntps1718_table_05_s1... And their information for Washington is just wrong, from their own source. It's also for the years 2017-2018.
