Interesting fact of the day
Here is an interesting fact, courtesy of this paper by Ed Glaeser and Charles Redlick: Although we typically assume that metropolitan areas like Detroit are shrinking because their residents are fleeing for better opportunities, this isn't true. Fast-growing cities also have high rates of out-migration. In fact, the faster a city grows, the more likely are its residents to move away during a given year. Cities decline because they attract fewer newcomers, not because their residents are more likely to move elsewhere.
(And, no, it is unlikely that the mere presence of UT accounts for Austin's high rate of emigration -- the Census Bureau does not count a student as a city resident unless he maintains his permanent residence in that city.)
Austin's high rate of out-migration and even higher rate of in-migration means that its population churns unusually quickly; i.e., newcomers make up an unusually large percentage of its population. This likely explains some of the friction between the old guard and the new guard (or "Californians," as they are more derisively known). Old-timers are shrinking as a percentage of Austin's population faster than anywhere else.


I would still expect cities with big colleges to show large outmigrations (if and only if the city is big ENOUGH to keep grads at least marginally employed for a little while, and if and only if city is very attractive, thus keeping some sectors' wages depressed). Anectdotally you hear all the time here about college grads working in bars or restaurants for a few years because they don't want to move away (not possible in TRUE college towns because there aren't enough jobs, but more than possible here).
