Around this time in 2016, gas prices were cheaper.  What does that mean?

According to mlive, Michigan is one of the few states that did not see a decrease in gas prices in the past week.  Not only did Michigan not see a decrease, it saw an INCREASE in gas prices.  The average price for unleaded gasoline is $2.20 per gallon, up 67 cents from last year's average.

Prices were about $2.19 per gallon in the Traverse City area, while the highest average was about $2.39 in the Marquette area. It was the fourth consecutive week that Marquette had the highest average price in the state.  In the Detroit area, the average price was up 2 cents from a week ago to about $2.22 per gallon.  AAA Michigan surveys daily fuel prices at 2,800 gas stations across the state. - mlive

Michigan is not one of the 37 states to see a decline in gas prices in the last month.  Why wouldn't Michigan's prices decline if there are so many states seeing cheaper gas prices  AAA Michigan says

"...gas prices statewide have risen by about4 cents per gallon in the past week. The Dearborn-based auto club says Monday the average price for self-serve regular unleaded gasoline was about $2.24 per gallon. That's about 67 cents more than it was at the same point last year." - Detroit Free Press

I remember when gas prices rose to about $4.00 per gallon 3-4 years ago so, no need to panic just yet.
