What organization is formed by business people to protect and promote the commercial interests in a community?

The chamber of commerce is an organization specifically designed to represent and advocate for the interests of businesses within a community. It serves as a collective voice for local business owners, allowing them to unite their efforts in promoting economic growth and improving the business climate. Chambers engage in various activities, including networking events, advocacy on policy issues, and providing resources for business development.

In contrast, other options such as trade associations typically focus on specific industries or professions rather than the broad commercial interests of an entire community, while business federations may represent a wider range of associations across different areas but do not solely focus on community interests. Economic councils may address regional or statewide economic strategies but lack the localized focus on promoting and protecting commercial interests that chambers of commerce maintain. Therefore, the chamber of commerce is the most appropriate choice for an organization formed by businesses to support their collective interests in a community.
