Chapters 1 provides historical tables on the rate of pay for Members of Congress since 1789; details on enacted legislation with language prohibiting the automatic annual pay adjustment since the most recent adjustment; the adjustments projected by the Ethics Reform Act as compared with actual adjustments in Member pay; and Member pay in constant and current dollars since 1992. Chapter 2 contains information on actions taken affecting each pay year since the establishment of the Ethics Reform Act adjustment procedure. Chapter 3 provides basic information on congressional salaries and allowances and recent developments.
