Sheepshead Bay is a mostly residential community, with significant restaurant and tourist facilities near the shore, businesses which had fallen into decline after World War II but have enjoyed substantial revival, especially with the influx of immigrants from the former Soviet Union, China, India, Pakistan, Vietnam, Israel, the Philippines, Poland, and Guyana. Sheepshead Bay is served by the BMT Brighton Line's Avenue U, Neck Road, and Sheepshead Bay stations, the latter of which is an express station.
