Michigan's
Prosperity Growth Gap Narrows
Greater Lansing Business Index: 115.1

In the late summer, a decline in Lansing-area motor
vehicle production led to a modest drop in local business
conditions. The Greater Lansing Business Index declined
from a level of 118.1 in April to 115.1 by August,
a 2.5 percent drop.
During the past year, the Greater Lansing Business
Index has been essentially unchanged to slightly lower.
Weakness in motor vehicle production and employment
has diluted the more favorable gains from hotel occupancy,
residential real estate and local area stock prices.
After four years of above average growth at the
national level, state and local business conditions
have failed to match U.S. growth rates. For example,
at the state level, growth in prosperity (defined
as the combination of personal income growth plus
household employment growth) has trailed the overall
United States for the last five years. The chart and
table below, which compares the United States with
Michigan, demonstrates the difference. This is in
contrast to much of the 1990s, when Michigan often
exceeded or matched U.S. growth rates thanks to national
and global cyclical forces having a greater benefit
for Michigan and Lansing-area business conditions.
While U.S. prosperity growth has exceeded Michigan,
encouragingly, the gap is narrowing. Table I shows
that the current prosperity gap is approximately 2
percent, versus more than 4 percent for most of 2004.
The recent better news on unemployment rates, regional
sales growth and state revenue collections confirm
a moderate improvement in the economy.

To create a comprehensive barometer for local business
activity, the Greater Lansing Business Index combines
six local economic variables:
1. Residential housing units built (seasonally adjusted)
2. Motor vehicle productions (seasonally adjusted)
3. Hotel occupancy rates (seasonally adjusted)
4. Kilowatt per hour usage (seasonally adjusted)
5. Ingham County employment
6. Local area stock prices
