Net brain gain/drain rates compare the percentages of people 31 to 40 who moved into versus out of each state and who are considered “highly educated,” which is defined as being in the top third of the national education distribution. For example, if 10% of those in that age cohort who have moved into a given state are “highly educated” and 20% of those who have moved away from that state are “highly educated” then the net rate would be -10. Scroll over a year to see brain gain/drain rates from that year.
