Long Beach Island is a barrier island and summer colony along the Atlantic Ocean coast of Ocean County, New Jersey in the United States. Aligned north-south, the northern portion is generally slightly higher end low-density residential, whereas the southern portion possesses higher-density housing and considerable commercial development. The primary industries include tourism, fishing, and real estate. The only access point to the island by land is a single causeway. The island is home to about 20,000 people on a year-round basis. The population is distributed among six separate municipalities, the largest of which is Long Beach Township. However, the island's population swells significantly during the summer months and reaches about 100,000 people, including part-time residents and tourists, who are often referred to as "shoobies". The island's close-knit communities are largely affluent and contain vacation homes for wealthy individuals who reside elsewhere, primarily New Jersey as well as New York, Pennsylvania, and Connecticut.
