Ancestry Ethnicity
In this lesson students are led through a series of steps to describe spatial patterns of various data layers representing ancestry. The data for this exercise is form the 2005 U.S. Census self identified Ancestry. Students describe the spatial distribution as dispersed, clustered, or random. Students explore the different minimums and maximums of data ranges and discuss how a lack of awareness of these differences can mislead a map reader. Students learn about normalizing data, develop Boolean logic queries to explore correlations.The county-level data used in the exercise are from the US Census Bureau Census 2000 Summary File 3 (SF 3) - Sample Data PCT 18 and Census 2000 Summary File 1 (SF 1) 100-Percent Data P3.
