Some of the comments concerning private vs. public should consider that classifications vary. This extends beyonds sectarian and non-sectarian colleges as well.

For example, Pennsylvania, comparatively, highly subsidizes private higher eduation in the Commonwealth. Penn State, Pittsburgh, Temple, and Lincoln are State Related insitutions, not state owned and operated. The State System of Higher Education (the Pennsylvania publically owned insitituions) has 14 Division II campuses. They are as follows: Bloomburg, IUP, Edinboro, California of PA. Shippensburg, Lock Haven, Mansfield, West Chester, Cheyney, Kutztown, E. Stroudsburg, and Millersville.

Penn State and the other State Related institutions, are technically private, are highly state subsidized, and have state representation on their Board of Trustees.

Those who term "Pitt" a city school, should note that association only due to location. Pitt has thriving branch campuses, notably the ones at Johnstown and Bradford. Penn State has multiple branch campuses throughout the Commonwealth.
