A Supplier Diversity program is a proactive business program which encourages the use of minority-owned, women owned, veteran owned, LGBT-owned , service disabled veteran owned, historically underutilized business, and Small Business Administration (SBA)-defined small business concerns  as suppliers. It is not directly correlated with supply chain diversification, although utilizing more vendors may enhance supply chain diversification. Supplier diversity programs recognize that sourcing products and services from previously under-used suppliers helps to sustain and progressively transform a company's supply chain, thus quantitatively reflecting the demographics of the community in which it operates by recording transactions with diverse suppliers.
Diverse- and women-owned business enterprises are among the fastest-growing segments of the U.S. economy. Diverse-owned businesses generated an estimated $495 billion in annual revenue in 1997  and employed nearly 4 million workers, while women-owned firms employed about 19 million people  and generated $2.5 trillion in annual sales.
Alongside the Women-Owned Small Business Program, the US Small Business Administration also operates an Economically Disadvantaged Women Owned Small Business (EDWOSBs) program for preferential award of federal contracts in certain industries.
