Why didn't I get accepted into Wisconsin- Madison?

[Eeyore123]

UW-Madison received close to 29,000 applications by Nov. 1 from students seeking an “early action” decision, suggesting an 8% increase in applicants and a new record for the fall 2018 freshman class, Mangelsdorf said.

Most of this increase is likely from OOS. In-state has been flat for years. My DS school went from 7(2016) to 9(2017) to 21(2018) according to naviance. It is out of state.
