Quick and dirty Census maps

Go to the American Factfinder website.

Click on “Topics” and choose people | age group | older population for this example, and then close the topics window.

Click on “Geographies” and choose an area. Choose Census Tracts | Florida | Palm Beach County for this example, and then “All Census Tracts within Palm Beach County” and click on “Add to your selections.” Close the geographies window.

Choose the table RELATIONSHIP BY HOUSEHOLD TYPE (INCLUDING LIVING ALONE) FOR THE POPULATION 65 YEARS AND OVER.

Click on “Create a Map” (one of the “Actions” in blue text, above the table).

To map males older than 65 living alone, click on the number 112 in the estimate column, down there near the bottom (or alternately, the 333 for females living alone).

Click on “Show Map” and wait a few moments for the map to load and you get a color-coded map showing which Census tracts have the most older men living alone in PBC.

Visualize what the media are saying with Media Cloud

Media Cloud is a system that lets you see the flow of the media. The Internet is fundamentally altering the way that news is produced and distributed, but there are few comprehensive approaches to understanding the nature of these changes. Media Cloud automatically builds an archive of news stories and blog posts from the web, applies language processing, and gives you ways to analyze and visualize the data. The system is still in early development, but we invite you to explore our current data and suggest research ideas. This is an open-source project, and we will be releasing all of the code soon.

Media Cloud is a project of the Berkman Center for Internet & Society at Harvard. Read more about the project or give it a spin here.

Find criminals in your neighborhood

Search an address anywhere in the U.S. and Criminal Searches Neighborhood Watch will map where the criminals live in that neighborhood. Information is taken from public records and includes everything from traffic offenses to violent crimes. I’m not sure how comprehensive the records are, based on a search of my own neighborhood, but it’s an interesting map/crime mashup.
