Court Stats
Don't miss out on the wealth of data on state court cases available at www.courtstatistics.org .
The data includes interactive tables which you can use to display statistics on trials; medical malpractice suits; case clearance rates and other metrics.
As you can see, the data shows how unlikely a civil case is to conclude in a trial. Data is not available on all metrics for all states, but there is quite extensive information on the disposition of cases in state appellate courts.
The site also includes charts illustrating the courts of limited, general, intermediate appellate, and last resort in each state.
