CU-Boulder 1998 Alumni One-Year-Out Survey
Population, sample, and reponse rates

Total population: In spring of 1998, the population included all degree recipients receiving degrees summer 1996 through spring 1997. In 1999, it included all degree recipients from summer 1997 through spring 1998.

Survey population: Population members for whom the CU Alumni Foundation had purportedly current and accurate addresses. This was about 90% of the population in 1998. We did not record this for 1999, however. To conserve resources, we used a different method of sampling. Instead of requesting the whole population of degree recipients and their addresses and then taking a sample, we requested addresses for only a sample of the total population.

Survey sample: A sample of the total population of degree recipients for whom the Alumni Foundation had a current address on file. Each group of bachelors and post-bachelors recipients within a survey year was selected so that it contained approximately 800 members. For bachelors recipients, this was approximately 20% of the "total population", and for post-bachelors, about 50%.

Reachable sample: Members of the the survey sample for whom the questionnaires were not returned as undeliverable (bad addresses). In 1998, 17% of the bachelors recipients in the survey sample and 9% of the post-bachelors were unreachable. In 1999, 14% of bachelors recipients in the survey sample were unreachable and 12.5% of post-bachelors were unreachable.

Survey respondents: "Reachable" sample members who returned completed questionnaires. 

Percentages are of the previous row. The last percentages shown are the response rates.
