By 1830, Providence had manufacturing industries in metals, machinery, textiles, jewelry, and silverware. Though manufacturing has declined, the city is still one of the largest centers for jewelry and silverware design and manufacturing. Services, in particular education, healthcare, and finance, also make up a large portion of the city's economy. Providence also is the site of a sectional center facility (SCF), a regional hub for the U.S. Postal Service. Since it is the capital of Rhode Island, Providence's economy additionally consists of government services.
