Census 2000 Lab Exercise







The Black population across the US is larger than the other races mentioned later on in this blog. The dark red spots represent the percentages between 53 and 86. This means the black spots in the south eastern parts of the US have more than half the population. This is a very large number since every other person you observe here are black. This probably resulted because of the slavery that existed years ago in the US. Most of the black people still reside in the south eastern parts of the US.

The Asian population across the US is fairly small. Asians mostly reside on the west coast, but there are certain areas in the east coast that have an Asian population. The west coast Asian population resides mostly in California and Seattle. The dark red spots represent percentages between 20 and 46. We can kind of understand why this occurred since the west coast is closer to Asia than the east. As a result, we see more or a higher percentage of Asians in Hawaii since it is even closer.

This map shows the percentage of "some other race alone" population in the US. We see that California has a high percentage of this percentage, and the dark red colors represent the percentages between 22 and 39. The south central part of US also has a high percentage. However, the east coast has a very low percentage. Since light yellow is close to 0 percent, the east coast has nearly 0 percentage of this population.

The Census map series exercise was very interesting since it reveals the diversity of the US. If you look back into the history of the US, these results make sense. For example, the black population resides in the south eastern part since of slavery in the south. The Asian population mainly exists in the west coast since it is closer to Asia. By observing the Census, we can conclude and analyze results. It is a very useful tool to help understand more about the ethnicities of the US.

GIS and this class have taught me the significance of the GIS mainly. The GIS plays a very large role in deciding many factors in life and regulations. For example, on the last day of lecture I learned that GIS played a large role on public safety. By collecting data and analyzing the results, we can help avoid more accidents in areas of high death rates. The GIS helps us make spatial decisions and find causes of problems. The GIS is essential in the modern world today.
