According to the National Center for State Courts in the United States, as of 2006 pro se litigants had become more common in both state courts and federal courts. Estimates of the pro se rate of family law overall averaged 67% in California, 73% in Florida's large counties, and 70% in some Wisconsin counties. In San Diego, for example, the number of divorce filings involving at least one pro se litigant rose from 46% in 1992 to 77% in 2000, in Florida from 66% in 1999 to 73% in 2001. California reports in 2001 that over 50% of family matters filings in custody and visitation are by pro se litigants. In the U.S. Federal Court system for the year 2013 approximately 27% of civil actions, 92% of prisoner petitions and 11% of non-prisoner petitions were filed by pro se litigants. Defendants in political trials tend to participate in the proceedings more than defendants in non-political cases, as they may have greater ability to depart from courtroom norms to speak to political and moral issues.
