week 8 lab's main purpose is to use GIS program to relate and join with statistical charts and tables to create these distribution maps with given data. First group of pictures are percentage of distribution of Asians, Blacks and Some Other Race.
First picture is the percentage distribution of Asians. From this map, we can clearly see that Asians are mainly cluster at the west coast, especially concentrated at California. Also there are some Asians clustered at north east United States, somewhere around New York.
Second picture is the percentage distribution of African Americans. From this map, we can see that African Americans are mainly living at South East of United States. This trend is come from the history of United States, when United States used to allow slavery, and American people at South bought many Slaves from Africa to do labors. Many African American choose to stay at South even after civil war.
Third picture is the percentage distribution of some other races. These races are including Hispanic and middle eastern people. As we can see, many Hispanic people are clustering at south west area of America. This area used to be part of Mexico, until American has won the Mexico-U.S. war and bought the land from Mexico.
The second group of the pictures are census 2000 tutorial, which consists four major maps. From Number of people in 2000, we can see that most people are staying along the coast of U.S. and second picture the population growth shows that population in California, Nevada, Florida and New York is growing rapidly, while middle part of U.S. are leaving for the past decade. The third picture show the percent change in total population, to show that Nevada has the most dramatic population growth, follow by Florida and California. With population density at fourth picture, it shows that New York, California, and part of Florida are the most crowded place in U.S.
By using the GIS system to the distribution map, I found out that it is very easy to combine the table data with landscape map and create these informative distribution maps, when you learned how to properly combine the data and apply them. However, the data chart itself has a very restricted formation, and you have to have the correct formation in order to let the data to relate and combine. Overall, I had a very easy time to create these maps and this skill is very useful in the future.
