US Census 2000


     According to US Census Bureau, the map provides spatial information about Asian population distribution in continental United States.  The darker purple area shows were the majority of the Asian population are concentrated.  In the States of California and New York has the majority of the Asian Population, specifically the the cities of San Francisco, New York City, and Los Angeles County.  While in the Great Plains and along the Rookie Mountains there are hardly any Asian population.  From what I can observed most of the Asian population are concentrated along major cities of continental United States.



     In the southeastern portion of the United States is where the Black population are located.  The southern states where most of the plantations were located and where Black population are concentrated.  The States of Mississippi, Louisiana, Alabama, Georgia, South Carolina, and North Carolina are the predominant states which have large Black population.  One particular region of interest is the southern portion of the Mississippi River, where there is heavy congestion of Black population.  The Great Plains, New England, and Rookie Mountains have hardly any concentration of Black population.



     The southwest portion of the United States is concentrated with an other race.  Since the concentration is in the southwest, along the US-Mexico border, I'm assuming the other race is Latino.  Also, southern Florida also stands out with other race, but not in the same magnitude as the southwest portion of the United States.  Most notably from the map is the southern portion Central Valley, a predominant agricultural region of California.  This particular region has heavy concentration of other race compare to the rest of the southwest.  Since most of the field workers are of Latino background and also to the areas history of hiring guest worker from Mexico (Bracero Program) I'm assuming Latino is the other race.


    Overall the census map series provides geospatial information of where certain ethnicities live within the continental United States.  One population that I was surprised with was the Black population concentration in the south; I assumed that Midwest would have bigger population than the south due Industrial Revolution migration.   Besides the census map series, GIS has become more easier and fun.  This new perspective has to do with my growing knowledge of GIS usage.  Besides having more knowledge on GIS usage, it allows me to better provide spatial information to any map user.  Now creating maps can be made from my perpective to spread better geospatial information to map viewers.
