I rant a bit about the way the debate around education acts as if entire generations of children have a permanent setback in their education.
I am not too excited by this graph to be honest. I took a look at some education and enrollment statistics from the Census. The base for the percentage is children over three enrolled in school. The analysis also includes college and graduate school enrollment. This explains why the Grand Forks and Cass counties show such a low number. Their university enrollments work against them in this regard.
