SPSS manages to keep their throne as the most widely-used statistical analysis software in social science. They have outdone themselves, yet again, with SPSS 20.

The Maps feature is at the forefront of the collection of new updates in this recent release. Now, you can incorporate geography into your quantitative research, in order to visualize geographical observations or trends.

This feature is contained in Graph > Graphboard Template Chooser. There are three types of map templates:

  1. Choropleth Maps, where you can use color gradation to reflect the value of statistic on a variable (mean, median, and sum).
  2. Mini Charts, displaying a chart for certain regions; each labeled with the respective location.
  3. Overlay Maps, combining two map files into one visualization; one as reference, another for data display.

You can work with the following data:

  1. Latitude and Longitude, in order to generate a reference map with geographical coordinates.
  2. Existing map files: ESRI shapefiles easily converted with the Map Conversion Utility
  3. Pre-installed maps in SMZ format, including the U.S. map with states and cities indicated

For additional map files: “Many of the templates in this product are based on publicly available data obtained from GeoCommons (http://www.geocommons.com) and the U.S. Census Bureau (http://www.census.gov). Another source for U.S. federal, state, and local geospatial data is the U.S. Geological Survey (http://www.geodata.gov).”

There are various ways to customize your map to display the data as you desire, including color schemes (stylesheet) as well as Pie on a Map.
