NOTES: Counts are based on the last recorded state of residence and the last recorded move for each enrollee during the study period, so that each enrollee is counted only once.
Excluding 364,540 people who were enrolled in more than one state with the same starting month for at least two state-specific enrollment episodes.
The in-migration rate is the # of moves to a state (last recorded move) divided by the # of state enrollees (last recorded state of residence).
