The 2004-2005 survey was initially conducted as a web-only
data collection. Follow-up efforts provided agencies with
fax and mail-in response options. Nearly two-thirds
of responses were received electronically through
the survey website. The remainder were received by mail
or fax. For agencies not responding to the full survey, an abbreviated survey instrument was used, giving agencies the
opportunity to provide data on type and number of personnel,
use of sworn officers, use of armed officers, physical
campus characteristics, and number of crimes reported to
campus law enforcement authorities. All non-respondents
provided at least some of this information.
Agencies serving 4-year United States universities and colleges
with a fall 2004 enrollment of 2,500 or more, and those serving 2-year public colleges with a fall 2004 enrollment of 10,000 or more were surveyed. United States military academies and for-profit institutions were excluded.
All four-year institutions of higher education within the
United States with 2,500 or more students.
The final response rate was 82 percent, with 749 of 913 potential respondents participating in the survey. Nearly two-thirds
(65 percent) of responses were received electronically through
the survey Web site. The remainder were received by mail
or fax. Among 4-year institutions, 606 of 750 agencies responded to the full survey, for a response rate of 81 percent. Among 2-year institutions, 143 of 163 agencies responded to the full survey, for a response rate of 88 percent.
