US Population Choropleth Map



I chose the Albers Equal Area Conic for the contiguous US and the Albers Equal Area Conic for Alaska and Hawaii respectively. This is a commonly used projection for the US. A color scheme from Color Brewer was chosen to accent the unipolar, sequential scheme of the data. The intervals were adjusted to more realistically represent the population changes.

Data Classification Lab


I felt that the equal interval with 4 instead of 5 breaks best fit the mean and standard deviation with the least variance.

This is an amusement park yet we don't know where, there is no title. Although there is somewhat of a legend, you must know what those symbols mean to understand them. There is no scale, so there is no way to tell how far from one place to the next (which might be deliberate) and I can only assume where parking and/or transportation might be located to find a way out of this maze.

This first map shows a change in population growth of major cities of the world from 1955 to a projected 2015. The map is easy to use, clear and legible; the symbols and labels are appropriate, and the purpose is easily identifiable; and there is structure and order. The circles/size correspond to the population of the cities originally and are proportional to each other and time. The legend is weak, if it can be called one (perhaps because it was an animation?) and there is no scale but the focus and purpose work well.

The order I've chosen my states reflects that I love the heat and because of that, the south. I also cannot be too far from a coastline, just a phobic thing having grown up in Florida. Most of my family is in the southeast and I like them so I like to be close enough that visiting is not a hardship. Florida and Texas are my favorites for weather and terrain and I hope to move to Texas in the next couple of years. (Also, no state income tax.)
