Which organization, founded in 1943, is the largest U.S. advocacy group representing small and independent businesses?

The National Federation of Independent Business, founded in 1943, is a major U.S. advocacy group representing small and independent businesses.

The organization was established by John W. Turner and is commonly known as NFIB. It describes itself as a member-supported nonprofit that represents small-business owners in public-policy debates, including taxation, regulation, labor rules, and health care.

NFIB differs from the U.S. Small Business Administration. The SBA is a federal government agency that provides programs such as loan guarantees and counseling, while NFIB is a private advocacy and membership organization. It also differs from the U.S. Chamber of Commerce, which represents businesses of many sizes and sectors.

NFIB has become especially known for surveys measuring small-business optimism and concerns. Its membership model gives individual owners a collective voice, illustrating how small firms can participate in national policy discussions despite lacking the resources of large corporations.
