Lab 7 Week 8



The first map focuses on the percent of asian in Us counties based on 2000 census data. The concentration of Asians in the Northeast, Northwest, and especially California shows that heavy asian density is on the coast and is relatively heavy in cities, especially gateway cites such as the San Francisco bay area and Los angeles where their are heavy dense quantities of asians, along with cites like New York and seattle to a lesser extend. However the asian population the percent of the asians population in the interior of the united states is very low except in cites such as Denver and Chicago.

The second map covers the percent of african americans in us counties based on the 2000 census data. There is heavy population percent concentration in southeastern and southern states excluding florida. Their is also a pocket of African Americans in southern California surrounding Los Angeles and in and around the cities of Chicago and Detroit. The Highest percentage of african americans in America appear to be in the areas to the east of the appalachian mountains and around the lower Mississippi river.

The final map is of the percent of the Other race according to the 2000 census data. The Label of other is a lose definition of the hispanic population in the us. The heaviest percentages of Hispanic population in the US in along the mexican american boarder running from southern texas along the rio grand to Los Angeles and up the central valley in California. This indicates the heavy amount of hispanic immigrants coming from central america and south america, traveling to parts of the us close to the boarder. Their is also a small pocket of hispanics in florida showing the large cuban population there.

These Census maps do a great job of illustrating the distribution and concentration of different minority groups in America county by county and their majority representation in a few select areas. while creating the maps it can be easy to alter the appearance just by changing the percent scales to highlight or disguise the percent of the group population across the county. ArcGis has been tedious to learn and can be frustrating but overall produces interesting and practical results.
