When I’m traveling, I always find it super-creepy when a bustling downtown turns into a ghost-town at night. Sidewalks should always have people on them, I say. In various different positions.
Most places in the United States, though, are subject to this spine-tingling effect. In many places, daytime population is higher than nighttime population, as commuters flow in to do their thing, and then flee for home at night.
In some places, the effect is more pronounced than others. For example, 30,000 people come to work in Lake Buena Vista Florida, but there are only four full-time residents. (And you have to wonder about who they are.) Other places that bring the crowds by day but drive them out each night: Teterboro, NJ, East Garden City, NY, Tysons Corner, Va. Beverly Hills also has a similar dynamic: 45,000 people live there, 90,000 people work there. So that’s one thing that Beverly Hills shares with Teterboro, at least.
In a very few places across the country, though, there’s more of a vampire dynamic: daylight drives the throngs away. So either these places are packed with the un-dead, or, the residents who leave for work each day don’t hire people in great numbers to manage things while they are out. In Aurora, Colorado, for instance, the population drops by 18%, or 50,000 people during daylight hours. Other vampire towns: Mesa, Arizona; Long Beach, California; Arlington, Texas, and Virginia Beach, Virgina.
