"It was great to see activity in the Detroit area accelerate along with the national economy this summer," according to Dana Johnson, chief economist at Comerica Bank. "Looking at the components of our index, the improvement in the local economy was broadly based over the past three months. Looking ahead, the key question is how much that momentum will slow in reaction to surging energy prices and ongoing consolidation in the auto industry."

Comerica Bank compiles the Detroit Area Business Activity Index (DABAI) monthly from eight different measures of regional activity which are seasonally adjusted, corrected for inflation, and expressed as an index, with 1996 as base year equal to 100. The Economics Department of Comerica Bank has calculated the DABAI monthly since 1957, depicting Metro-Detroit's economy over seven full swings of the U.S. business cycle.
