Omaha Conditions Survey
The Omaha Conditions Survey: 2004 was conducted through telephone interviews with adults from a random sample of Omaha-area households. The sample was drawn from households in the Nebraska portion of the Omaha Metropolitan Statistical Area (MSA). Douglas, Sarpy, Cass, Washington, and Saunders Counties comprise the Nebraska portion of the Omaha MSA.
Telephone numbers were selected for the sample using a random digit dialing design. This design allows for the inclusion of both listed and unlisted telephone numbers in the sample.
