"Similar to so many other measures of economic activity, the decline in our
tourism index accelerated markedly in late 2008," said Dana Johnson, Chief
Economist at Comerica Bank. "With the national and state economy still clearly
contracting in early 2009, further declines in the Michigan Tourism index seem
inevitable, as households and businesses cut back on discretionary travel. By
midyear, however, declines in tourism are likely to become less severe, as
recessionary pressures begin to moderate."

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. Historical index
levels are available upon request.
