Why do the counts in the Data Browser differ from the current number of participants?

There may be a delay of several months between the time a participant consents and the time their record is included in the All of Us data that is available in the Data Browser. The delay is a result of the time it takes for participant data to be collected, transferred to the Data and Research Center and curated. As a result, the overall participant counts within the Data Browser are lower than the overall enrollment numbers for the program.
