Most of Centereach was built recently: 4% of its homes predate 1940 and the median home dates from 1970. Below: 3 old photos and papers, maps from 1902 on, and the census since 1960.
The hamlet of Centereach was first called West Middle Island, but primarily became known as New Village until the early 20th century. When it was discovered that another village shared the same name, the name was changed to Centereach in 1916. The name Centereach reflects the centrality of the hamlet's location on Long Island, literally meaning "center reached".
Over the years Centereach has progressed from a small hamlet to a primarily suburban community. The population in 1940 was only 628, but the area had grown to nearly 20,000 residents by 1970.
The two earliest suburban developments, which began in the early 1950s, were Dawn Estates and Eastwood Village.
