Why map data?

• Basis for statistical mapping:Any kind of data that can be expressed numerically and varies in quantity from place to place can be mapped.

Statistical mapping requires two criteria:– Data has a numeric value– Data has a geographic element

• Choropleth maps are very useful tools for representing numeric data (population density; percentages; location quotients)

• ArcGIS (ArcView) is software of choice for 3P47 assignments.

• Provides operations for calculating statistics and “joining” data to geography.
