Yep! If you combine DFW (2.2m), it's rivaling #4 Houston (2.3m) and approaching #3 CHI (2.7m).
The DFW growth rate (2010-2017) is higher that most of the other top cities. Ft Worth (0.8m) at 18%, Dallas (1.3m) at 12%... #3 HOU at 10%, #7 PHX (1.6m) at 13%... but the top growth spots are #11 Austin (0.9m, 21%), #17 Charlotte NC (0.8m, 18%), #18 SEA (0.7m, 17%) and #19 DEN (0.7m, 17%)
#3 CHI (2.7m) is stagnant at 0.7%, so they'll get passed soon.
Understandably, massive LA (4m) and NY (8m) are both at around 5%. Tough to grow more when you're that big.
Just go down I-35 from the Oklahoma border all the way to San Antonio and it’s just becoming one massive googleplex.
