Hi there, I'm from Austin, Texas.
I know a lot about Austin. It's the 11th biggest city in the USA by population.
Oh really? I did not even know that. I knew it was a big city, but 11th biggest US city puts it into another perspective!
It's actually also the fastest growing large city in the US, and it has one of the highest populations of capital cities in the country.
That's quite the feat. Texas in general has a large population so I suppose it makes sense.
Texas does have a large population. Austin is only the 4th in highest populations of cities in just Texas alone. 
Ahh, yes, Dallas and Houston come to mind when it comes to large Texas cities. I am unsure of the others though.
The other one would be San Antonio, it has the second most people and is the second largest city in Texas.
How could I have forgotten about San Antonio! I suppose I underestimated its size. But yes, Texas is a very big state, many do not know its popularity.
Yes that's true. Many people don't know it but Texas is huge, it's the second biggest state in both size and population.
