Variable rate sampling may be used across a set of software services or for the same software service to construct a sequence of sampling sets. Users are selected over a time period using a sampling scheme to create the sampling sets. The sampling rate may change over time depending upon the underlying data that is desired, the software service that is used, and the anticipated population of users that may access the software service. The sampling sets may be combined to develop a common set for subsequent analysis to provide information regarding a total population of users.
