* The items dealing with desire for part-time work in the 1999 and 2004 surveys were not identical. The estimate for 1999 is the percentage of people who indicated that they worked part-time because they preferred part-time employment to full-time. The 2004 estimate is the number of part-time faculty who responded “not preferred” to a question that asked whether they preferred to work full time. The assumption made here is that these individuals preferred to work part-time, although another possibility is that a certain number of respondents had neutral preferences for employment status.
