Identifying the US region associated with a state

A list of the specific states composing each US region are included here.

Identifying where students live for the "All Students" Tables

Students can have addresses of different types on the student records system. If the "mailing" address of the student was in the commuting zip code range then we took that. Otherwise if the "permanent" address was in the zip code range then we took that if the student was a graduate student. If the student was an undergraduate we took the "permanent" address only if the student lived in a residence hall in the four years prior to the check, and the current "permanent" address is different from the "permanent" address when the student lived in the residence halls. For 2001 and later, the zip code from personnel files was used last if the student's University of Colorado employee zip code was in the defined range. Otherwise we set the student's zip code to be unknown. After identifying a zip code for each student, we identified the county corresponding to the zip code if the location was in Colorado, or to the US region if the zip code was outside of Colorado.  Examples

• Sally, mailing 80302, use 80302
• Jerry, grad student, no mailing address in range, permanent 80304, use 80304
• Connie, law student, no mailing address in range, permanent in Texas, no zip used (unknown)
• Tom, undergrad, no mailing address in range, permanent in New Hampshire, no zip used (unknown)
• Bret, undergrad, no mailing, permanent 80304, lived in a res hall 3 years ago, permanent zip in California when lived in the res hall, take 80304
• Robin, undergrad, no mailing in range, permanent 80304, lived in a res hall last year, permanent zip 80304 when lived in the res hall, no zip used (unknown)
• Zach, undergrad, no mailing in range, permanent 80304, has not lived in a res hall in the prior 4 years, no zip used (unknown)
• Joe, undergrad, no mailing in range, permanent 80304, has not lived in a res hall in the prior 4 years, employed at UCB, employee zip code is 80304, take 80304.
• Sara, undergrad, no mailing in range, permanent outside range, employed at UCB, employee zip is outside range, no zip used (unknown).

A change in method. In analyses done in 2001, we took permanent addresses in the zip range for all students with no mailing address. We now believe that substantial proportions of the addresses we thought were local, and that we used in analysis, were actually parent addresses. Of course the problem was more severe for Colorado residents, many of whom have parents in the Denver-Boulder area in the commuting zip code range.
