There is a close relationship between the economy and small businesses. Small businesses continue to be incubators for innovation and employment growth. According to the U.S. Small Business Administration Office of Advocacy, small businesses make up more than 99.7% of firms with paid employees, account for 62% of net new jobs, produced 46% of the private nonfarm gross national product in 2008 (the most recent year for which the source data are available), and represent about 95.9% of employer firms in high-patenting manufacturing industries.
As you can see by the statistics, small businesses continue to play a vital role in the economy of the United States.
