Some Data Provided by U.S. Geological Survey and U.S.Census

  1. Geological "bars", not drinking establishments
  2. Levee locations are pre-Katrina
  3. U.S.G.S. designated "populated places" (around 179,000) do not necessarily sync with Census "populated places" (around 25,000) and often do not have a population counted for them.
