Notes

The numbers above are counts of unique sessions, not counts of how many files were downloaded. I.e., a value of 12 implies that users downloaded 1 or more files from the study as part of 12 discrete sessions/visits in this time period.

Please note that the numbers above do not include distribution of restricted-use or public-use data that are not web downloadable. E.g., data distributed on CD-ROM.

"SDA" refers to unique sessions by users analyzing data using Survey Documentation & Analysis, a web-based alternative to SAS, SPSS, and Stata.
