Jobs in the borough have traditionally been concentrated in manufacturing, but since 1975, Brooklyn has shifted from a manufacturing-based to a service-based economy. In 2004, 215,000 Brooklyn residents worked in the services sector, while 27,500 worked in manufacturing. Although manufacturing has declined, a substantial base has remained in apparel and niche manufacturing concerns such as furniture, fabricated metals, and food products. The pharmaceutical company Pfizer was founded in Brooklyn in 1869 and had a manufacturing plant in the borough for many years that employed thousands of workers, but the plant shut down in 2008. However, new light-manufacturing concerns packaging organic and high-end food have sprung up in the old plant.
