In the following indicators, 2008 United States data was missing for 2008 due to availability problem, and therefore a 3-year average has been applied (from 2005 to 2007) as the 2008 data, because these 3 indicators have been quite stable during the last several years.
1. Agriculture, contribution to economy (% of GDP)
2. Industry, contribution to economy (% of GDP)
3. Service, contribution to economy (% of GDP)
