Examples
Here is an example of choosing a map, creating a slideshow, and then creating a report from the map.
Choosing a Map
On the main maps page, we choose to get our data from the 1940-2000 maps.
We are then taken to the default map, which shows population density per square mile for the continental Unites States from the 2000 census.
We zoomed in on Maricopa County, Arizona, using the zoom tool, and in the legend changed the subject of the map to percent retail trade, under Industry.
Creating a Slideshow
We then clicked on a blank space in the slideshow bar to add that view of the map to the slideshow, then changed the year to the 1990 census tract. We added this view to the slideshow as well, and repeated this for the 1980 and 1970 censuses.
Making a Report
Here we are making a report from the 1970 map. We clicked the “Report” button at the top of the map, then chose Industry as the subject for our report.
We chose to select an area by placing points. We clicked to place points in the census tracts we were interested in.
We then clicked “Make Report.” Here is the report that resulted.
