To make this map I downloaded population projections for 2009 from the U.S. Census website. The U.S. Census is a more reliable source for projections than any other because their projections are based on trends since population data has been collected. I also used the congressional districts I had downloaded for the first map. I also downloaded the county boundaries from the U.S. Census website. I cleaned up the data in Excel and used the JOIN function to put the data into the attributes table, joining the tabular data with the shapefile. I selected proportional symbol dots to illustrate the population data. I did not use the psychological scaling to resize the dots since there is only one largest dot and it is already covering the whole county outline. I did not use a white outline because there was not too much overlap like some of the population maps we have seen and created. I went back to what we learned in Lab 6 to make this map. Dots are a standard way to illustrate population, so I like using this method. It matches the use of raw data.

Map of the week
If you want to think about something freaky, let’s think about aliens not coming here as they would likely just destroy us. So my map of the Week has to do with the fact that I think NASA should listen to one of the smartest men on the planet and stop sending out communiqués to unknown would-be destroyers!
