Particularly important sectors

Technology & Information is one of the strongest areas of the U.S. economy. BLS data show the information sector with projected output of about $3.78 trillion, while professional, scientific and technical services are projected at about $4.13 trillion.

Finance and insurance is another enormous sector, with BLS projecting approximately $3.92 trillion in output, while real estate, rental and leasing is around $3.47 trillion.

Professional, scientific and technical services is particularly interesting for a business directory because it includes legal, accounting, engineering, architecture, consulting, computer systems design, and other specialized businesses. BLS currently projects more than 10.7 million jobs in this broad industry, with computer systems design and management/technical consulting among notable components.
