2. Population Demographics

The figures indicated below are derived from the 1990 Census of Population and Housing: Summary Population and Housing Characteristics, New York (1990 CPH-1-34), published by the U.S. Department of Commerce, Economics and Statistics Administration, Bureau of the Census: Census 1990. The census figures are stated to hold for April 1990. At that date, Brookhaven County Subdivision Place (Brookhaven CDP) – Brookhaven and South Haven effectively -- was said to have had a population of 3,118. Based on these figures, the Long Island Lighting Company projected a population of 3,137 as of January 1, 1994, i.e., an increase of 0.6% or 19 people.2

The boundaries of the Brookhaven CDP as stated by the New York Regional Bureau of the Census (by telephone communication) are the following:

North: Sunrise Highway
East: Carmans River
South: Great South Bay
West: Bellhaven Road north to Beaver Dam; west to Bellport Avenue, north to Sunrise Highway.

The total square mileage of the Brookhaven CDP land area as reported in the Census Bureau statistics is given as 6 square miles. This effectively includes all of South Haven south of Sunrise on the east and parts of "greater Brookhaven" to the west. Following the boundaries agreed to in this study, the difference between the Census Bureau’s calculations (and those of LILCO) and ours would be approximately 0.9 square mile, resulting in a Brookhaven Hamlet of approximately 5.1 square miles in area. What is excluded from the BVA’s determination would be that area between Belleview Avenue and Bellhaven Road, west to Bellport Avenue, north to Sunrise Highway, east to Arthur Avenue, south to Beaver Dam Road, west to Belleview, roughly 0.9 square mile.

Population as per LILCO estimate (as of January 1, 1994):
