A thematic map is a map that represents a certain set of data. This thematic map represens the population by state of the United States. This data is the estimated population for 2006 using extrapolated data from the 2000 US Census. According to this estimation in 2006 there were over 299 million people in America. California, while a large state, accounts for over 10% of the overall population.
