"Our Index fell in the first quarter, paying back some of the unexpectedly large surge in fourth quarter's Index," said Dana Johnson, Chief Economist at Comerica Bank.  "Air travel, bridge traffic flows and museum activity were particularly hard hit, with little help from other sources of tourism activity.  Although the Index is down from recent highs, the generally improving trend reflected in the Index should be maintained over the course of the year, as personal and business discretionary spending continue to improve."

The Michigan Tourism Index is a quarterly summary of six equally weighted, seasonally adjusted travel, lodging and entertainment data series. These series serve as a proxy for statewide tourism activity.
