Interesting interactive map showing gun deaths in the US. The map is based on data from the U.S. Centers for Disease Control and Prevention and shows the average number of gun deaths per 100,000 county residents from 2004 through 2010.

Note that the “gun deaths” map combines homicides, suicides, and accidents.  There are also separate maps for suicides and homicides.  Suicides really skew the statistics.

Thanks to Barry Waite of the City of Carson for finding this one.

If you work with transit data, you might want to take a look at the following blog post.  Some great suggestions:

• Use services areas around transit stops instead of buffers around transit lines
• Incorporate frequency, like trips made per hour
• Consider travel time between places throughout the day
• Factor in transit frequency
• Incorporate demographic data to find what groups are underserved by transit or have a high level of need for better access to certain types of destinations
