Historical population
U.S. Decennial Census[6]


The first people to settle in the area were the Secatogue Native Americans. The unearthing of a Native American burial ground north of West Islip beach enabled historians to reconstruct a village of these Native Americans who lived along the edges of the Great South Bay, Sampawams Creek, Trues Creek and Willetts Creek.

Farming and fishing were the main occupations. In the mid-19th century, the completion of the Long Island Rail Road brought travelers to West Islip.

Today West Islip has its own fire department, post office, public library and Good Samaritan Hospital. A short drive affords access to good fishing and swimming.
