Week 8 Assignment

1. Black Population
This map shows the distribution of population of black people in the United States as a percentage. The more heavily populations of black people are located in the southern and southeastern United States. There are also some medium sized populations in southern California. However, there are hardly any large populations located in any other area.





2. Asian Population
This map shows the population distribution of Asian people in the United States as a total number. The percentages were very hard to get, so I reworked the map to get the total number of Asian people in each county. The data shows almost the exact same results. The highest concentrations of Asian people are in large cities, mostly in southern California, Seattle, Chicago, Houston, Miami, Boston, and New York City.





3. Some Other Population
This map shows the population of non-white, black, or Asian people in the United States as a percentage. The map is referring mainly to hispanic Americans. While this is not explicitly listed, it can be inferred due to the locations of the highly populated areas. The most populated areas are near the Mexican border in areas that are known to have high percentages of hispanic people. These areas include Las Vegas, Los Angeles, San Diego, Phoenix, and parts of New Mexico and Texas.

This census map series was a wonderful exercise in learning how to create population maps using ArcGis. While it was very difficult at the start of the project, the tutorial proved to be instructive and helpful in making the maps shown above. The census map series is especially nice because it gives us a way to visualize populations of anything, anywhere.

ArcGIS, as a whole, is a frustrating, yet magical tool. It is something that is applied to nearly every discipline, but requires the proper training to navigate the software. I know that it will eventually become more user friendly in the future, but it is still quite difficult to learn. However, once mastered, is so incredibly rewarding and helpful. Maps as simple as the ones in this project can be of magnificent help when trying to show someone else data. Raw data is useless; however, when given a way to portray it, it can be portrayed in a wonderful fashion.
