Lab 7




This map show the percentage of Asians by county in the Continental US. It is clear from this that Asian people are more concentrated in the coasts, with the West Coast having greater presence of Asians than the East Coast. I believe this is because of the proximity to the countries of origin, as well as the fact that the coasts are more internationalized with the interior.




This map shows the concentration of Blacks by county in the Continental US. We can see that there is a higher concentration of black population in the southeastern region of the United States. Areas such as Georgia, North and South Carolina, and Alabama show a higher proportion of blacks than the rest of the country.




This map shows the concentration of some other race alone, by county, in the Continental US. This comprises latino, hispanic, among others, so it makes sense that there is a much higher concentration near the US-Mexico border, so states such as California, Texas, New Mexico, will naturally have a higher proportion of "Other races".

The census data is very helpful when applied to a geographical visualization such as this. One can now contrast and compare data while also being aware of spatial locations. To conclude, we can see that the Asian population is more concentrated in the coasts, with the west coast having a higher concentration, the black population is in high concentration in the southeastern region and other races (predominantly hispanic and latino) are more concentrated in the southwestern regions bordering Mexico.

My experience with ArcGIS ended up being very helpful. I can now create maps showing statistical data about various fields. ArcGIS will be very helpful to me in the future, be it in class or in my professional life. It is a tool which allows for the visualization of data in a spatial context, which is extremely useful in economics and the business world alike. I hope I can get to learn more about this complex tool in the future.
