When viewed and analyzed together, economic indicators and market indexes can provide a clear picture of economic growth. The main measure of economic growth is gross domestic product, or GDP. If GDP declines, we can safely say that the economy is shrinking. Market data indicates that this change took place during the financial crisis in 2008 and 2009. These changes match trends in employment. As employment dropped, so did the economy's growth. Finally, these changes correspond to market indexes. Prices and market demand dropped as other indicators dropped in turn. All together, these indicators and indexes provide a clear pattern for analyzing economic changes.
