Explanation of the indicator:
GDP (Gross Domestic Product), the primary measure of production
in the U.S., refers to the quantity of goods and services
produced. Positive numbers in the chart reflect a growing
economy, while negative numbers reflect a shrinking economy.
Real GDP, which is the GDP adjusted for inflation, is used
in the chart.
In some cases, County-level data are not available from
the same data source used by the State. In other cases,
County-level data are not available for the same time frame
used by the State. In these instances, data sources and
time frames were selected that most closely match those
of the State. Due to this difference, it must be noted
that comparisons may not be completely equivalent in all
cases. Michigan's data source is the U.S. Department of
Commerce, Bureau of Economic Analysis.
