Counties are responsible for providing core services such as human services, criminal justice, public welfare and infrastructure to communities of all sizes across America. The conditions of a county economy can constrain and challenge county governments, residents and businesses, while also providing opportunities. To ensure the delivery of essential services, support job growth and maintain a healthy revenue base, counties invest in community and economic development activities in a number of ways. Counties most typically focus on workforce training, business attraction and retention, and regional marketing in their economic development partnerships. Collaboration is the key to successful county economic development initiatives.
