Credit unions are financial institutions formed by an organized group of people with a common bond. Members of credit unions pool their assets to provide loans and other financial services to each other.

Credit unions differ from banks and other financial institutions in that the members who have accounts in the credit union are the owners of the credit union and they elect their board of directors in a democratic one person-one vote system regardless of the amount of money invested in the credit union. A credit union's policies governing interest rates and other matters are set by a volunteer Board of Directors elected by and from the membership itself.

These factors allow credit unions to pay dividends to their members (not shareholders) and offer them lower loan rates, higher savings rates and fewer service fees.

The National Credit Union Administration (NCUA) is the federal agency that charters and supervises federal credit unions. They also insure savings in federal and most state-chartered credit unions across the country through the National Credit Union Share Insurance Fund (NCUSIF), a federal fund backed by the full faith and credit of the United States government.
