Methodological Notes

National Coverage of the Data  As of fall 2021, institutions actively submitting enrollment data to the Clearinghouse account for 97 percent of all enrollments at Title IV, degree-granting institutions in the U. [...] Using all IPEDS Title IV, degree-granting institutions as the base population, weights for each institutional sector and state were calculated using the inverse of the rate of enrollment coverage for that sector and state in the relevant year. [...] Given the unavailability of fall 2022 and fall 2023 IPEDS enrollments prior to publication, fall 2021 IPEDS enrollments were used as the basis for calculating the Clearinghouse coverage rates for fall 2022 and fall 2023. [...] The creation of separate sector designations for PABs by control (public, private nonprofit, and private for-profit), along with the designation of PABs at the branch campus level, leads to revised weights and updated estimates for fall 2018 to fall 2022 compared to the results published in the fall 2022 edition of this report. [...] Gender data for the remaining students were imputed using a table of name-gender pairs that the Research Center developed using data publicly available from the Census Bureau and the Social Security Administration as well as the institution-reported data.
