WASHINGTON (AP) -- Americans' confidence in all three branches of government is at or near record lows, according to a major survey that has measured attitudes on the subject for 40 years.

The 2014 General Social Survey finds only 23 percent of Americans have a great deal of confidence in the Supreme Court, 11 percent in the executive branch and 5 percent in Congress. By contrast, half have a great deal of confidence in the military.

The survey is conducted by the independent research organization NORC at the University of Chicago. Because of its long-running and comprehensive set of questions about the public, it is a highly regarded source of data about social trends. Data from the 2014 survey was released last week, and an analysis of its findings on confidence in institutions was conducted by The Associated Press-NORC Center for Public Affairs Research and the General Social Survey.
