I like this idea. For example, Clemson, SC's student population would
not be included in the US Census population data, but it arguably has
more hotels than Seneca, SC which is rendered above but has a larger
permanent population. Given the large amount of government business
transacted in Albany, it probably has a lot of hotels too.
