Day / Night Population Counts

It was not too long ago that I obtained daytime/nightime population estimates on the block group level for a landscape architect professor.

Well, this must be ahot topic as the US Census Bureau just released estimated daytime population counts for states, counties, and select places.

As I predicted, Dallas experiences the second-most percent change from day to night population for large cities. First was our neighbor Houston. Topping the list is Lake Buena Vista city, FL, which experiences a whopping 3076.80 employment to residence ratio. Yes, this boggles my mind.

So, now I have the task of joining these tables to feature classes, generating metadata, and including the files in our metadata catalog. Then students will have easy access to the files.

Lake Buena Vista, if I remember correctly, is the town in Florida where Disneyworld and all its attendant flourishes are located.
That might help to explain the high daytime surge in population....

Yes, I believe you are correct. It is great when we find an obvious area such as this where the numbers we use do indeed reflect reality. It helps to bolster my confidence in these numbers.
