Created by Congress under the Historically Underutilized Business Zone Act of 1997, the HUBZone program seeks to encourage economic development in historically underutilized business zones, or HUBZones, through the establishment of preferences for award of Federal contracts to small businesses located in these areas.

The HUBZone program is unique because it directs Federal contract dollars to small businesses located in areas of high unemployment and low-income to stimulate economic development. This combination provides a mechanism that reconciles the cost of providing Federal assistance to distressed communities with the need of the Federal Government to acquire products and services at fair prices. By using Federal procurement dollars to provide economic development, the HUBZone program is able to bridge the gap between the costs of Federal initiatives aimed at revitalizing distressed communities with the benefits of market-based economic development. Further, the employee residency requirement takes advantage of the socioeconomic theory of the “multiplier effect.” The multiplier effect asserts that each dollar injected directly into a local economy is spent several times within that community, thereby ratcheting upward the overall economic impact of each dollar.

Delta-21 has steadily raised the economic status of HUBZone employees and our local community by providing employment opportunities and training initiatives to the underserved citizens of Knoxville. These community building efforts benefit the city, state and federal government by taking individuals off of state and federal welfare programs, providing them with quality jobs and promoting long-term local investment, thereby improving the economic climate. To date, Delta-21's support of the HUBZone program has resulted in a direct community investment of over 2 million dollars.

With more than 47 million Americans living in poverty, Delta-21, whose name signifies change for the 21st century, is striving to make a positive impact on the inner-city of Knoxville, and the surrounding rural counties.
