Social capital

The blogsite The Oil Drum: New York City has an interesting map of the United States that displays the amount of social capital per state.

In this context, it indicates the sense of community and interconnectedness people feel. The map is based on the results of a survey - it suggests by Robert Putnam, author of a book on social capital called Bowling Alone - which states that regions such as Vermont and North Dakota have higher levels of social capital than Nevada or Alabama.
