Earlier in the week, the annual report  from the Transactional Records Access Clearinghouse at Syracuse University  was released and it contains lots of fascinating tax data from 2008.  It includes statistics about salaries and tax revenue from over 3,000  counties across the nation. The New York Times posted a great article  on what the data suggests, and you can find a section of their piece  below or the full  text here.
 
Some of the findings based on tax data from 2008:
 
- When it comes to exemptions claimed per taxpayer, Utah County (Provo), Utah, has the highest rate in the country, at 2.76. Residents of New York County (Manhattan) in New York claim the least number of exemptions on average, 1.54 per taxpayer.
- Average wages and salaries were highest in Loudoun County (Round Hill), Va., at $85,028. They were lowest in Catron County (Glenwood), N.M., with an average of $14,289.
- Combining all sources of income, Teton County (Moose), Wy. was No. 1., with an average of $142,048 in adjusted gross income. Adjusted gross income was lowest in Douglas County (Ava), Mo., reporting an average of $18,262.
