Gender Imputation
National Student Clearinghouse
In late 2007, the National Student Clearinghouse (NSC) expanded its Enrollment Reporting service to include several additional data elements (commonly referred to as the "A2" or "expanded" data elements). One of these expanded data elements is student gender. Although gender is potentially important to a number of research projects, it is currently an optional data element in Clearinghouse Enrollment Reporting. Consequently, postsecondary institutions have populated this field in a limited percentage of enrollment records. However, as Figure 1 illustrates, this percentage has been growing steadily since 2007. While the NSC Research Center expects this trend to continue, in order to make immediate use of the gender data element for research, it is necessary to impute its value for the majority of Clearinghouse enrollment records. To meet this need, the Research Center developed an imputation process in which previously submitted name-gender pairs are used to determine the probability of any first name being associated with either gender. To increase the accuracy of the imputation process, it also draws on name-gender data from the Social Security Administration and the U.S. Census Bureau. The Research Center's report on Fall 2012 Current Term Enrollment Estimates, released in December 2012, marked the first application of this gender imputation process in a Clearinghouse research project.
