While insurance increases have been trending downward, the worst year-on-year increase has been 13% for families and 15% for singles, both in 2002.  The rate of increase has been declining, with a local peak in 2011 of 7.5% and 9.5% for singles and families, respectively.  A flashback to the premium increasing heydays of 2000-2005.
