National Association of County Engineers

The National Association of Counties (NACo) was created in 1935 when county officials wanted to have a strong voice in the nation's capital. More than six decades later, NACo continues to ensure that the nation's 3066 counties are heard and understood in the White House and the halls of Congress. NACo's membership totals more than 2,000 counties, representing over 80 percent of the nation's population.
