The federal courts have published their annual statistical report for the fiscal year that ended on September 30, 2012. A total of 17,645 Social Security civil actions were filed that year. The busiest district was the Central District of California with 1,134 Social Security civil actions. However, I'd guess that relative to population the Western District of Missouri with 743 civil actions was the busiest district. Only 19 Social Security civil actions were filed in the Middle District of Louisiana, based in Baton Rouge, 8 in North Dakota and 6 in Hawaii.
