After doing some searching I finally found a l
isting of US metros by total college enrollments, and the results are a bit shocking:
LA has a larger population of college student than Dallas, Huston, and Austin
combined. Of all the metros with more than 1 million residents, at 7.34% LA has the highest fraction of college students compared to total population. Austin is at 5th with 7.13%, and no other Texan city falls in the top 10.
