BlackPanther, as a Virginian, you will get this reference, Carolinians, correct me: but I always imagine Charlotte like Rosslyn Arlington. It's this big cityscape with tall buildings, stock tickers, restaurants, plazas, cabs everywhere. But at night it's friggin' deserted. There's not a soul there because no one actually lives there. It's just a city that's alive in the daytime when everyone comes there to work, and then after rush hour everything shuts down. It's not a 24/7 city like Washington D.C. or NY, or Chicago, etc. I imagine Charlotte the same way. Bankers and businessmen commute in during the day, and then back to the suburbs at night, leaving the few college students who actually live in the apartments in the city proper to wander the streets like lonely sentinels.
Most of the people that live uptown are young professionals. The only college students that really live uptown are the few that go to Johnson and Wales.
No college students are going to pay $1200+/mo for an apartment and then commute back up to the university area.
Less than 1% of residents in Uptown are in their teens. The most populous group residing in Uptown is people in their 30's. There isn't much variation in % of population between people in their 20's, 30's, or 40's though.
Certain areas of Uptown are busy until 2-3 in the morning, while other areas are dead after 5. Second Ward, which is mostly government buildings, is pretty dead and soulless after 5pm, but Tryon, College Street, Church Street, and many of the streets that intersect those have a good bit of street activity.
With all the projects taking place in Third Ward right now (the quadrant where the BoA stadium sits), that should become a hot spot in Uptown in the very near future as well.
I don't know that any areas of Arlington are really great comparisons because Uptown varies depending on where you are. Some areas are comparable to Rosslyn, some are more like Ballston, and others more like Clarendon. Instead of being linear like Arlington though, Uptown is more of a square with each quadrant having varying levels of activity.
