Walking Into a New School Year

This odd graphic from the Biennial Survey of Education in the United States 1934-36 shows the number of school days per state.

The states appear to be marching off to school. In order to see if there's any pattern I tried making my own map. However, many states are not shown.

 Some other interesting graphics from the report show the states grabbing bags of money,

children lining up in the schoolyard by year,

and the percentage of students enrolled in private schools - overrunning the Northeast.

 The report is available here.
