Waco, Texas is quite conservative–even by Texas standards–so that may explain in part the reluctance of students to apply to Northeastern LACs.
With respect to “systemic analysis”, all I can suggest is to contact individual schools for their career placement stats.
Typically, I see questions regarding whether or not a non-elite school outside of the Wash DC to New England region can place graduates into competitive financial employers in the Northeast region so it is nice to read a post concerned with placement in Texas or in the Pacific Northwest.
