![]() They prepared datasets showing over 60 years of urban change, from 1928 to 1993. The USGS Urban Dynamics Research Team documented urban extent through time to evaluate land use/land cover changes and assess the impact of development. The culture is also altered because lifestyles are changed as suburban growth encroaches on small towns and agriculture communities. Human induced changes to stormwater drainage affect aquatic habitats through changes in stream runoff (more rapid response to precipitation, higher discharges, and longer lasting peak flow events), water quality (temperature and contaminants), and diminished recharge to the water table (which affects water supplies for existing communities). Culture changes demand more water, land, and transportation per person.Ĭhanges in land use may have equally dramatic effects on local natural resources, as well as the human and physical ecology. Population increases the demands for fresh water. Often quality of life issues and cultural changes occur to the human population as result of this transformation. Between 19, metro New York's population grew only 5 percent, but consumed 61 percent more land, (McMahon, Edward T., 1997, " Stopping Sprawl by Growing Smarter"). Once agricultural land is lost in a given area, its food production potential is also likewise diminished. Losses of undeveloped land have direct impacts on the physical, biological, and social resources of an area. Census data using block group areas.(Public domain.)Īs urban development changes the immediate areas of land use, effects throughout the local environment can be observed. View Media Details Map of 2010 population density calculated from U.S. ![]() Along with the general pattern of progressive eastward decrease in population density there has been a trend of preferential urbanization along the north and south shores. The pattern of population density mainly reflects the gradual eastward transition from the highly urban communities characterized by high-rise apartment buildings in Kings County, to the suburban communities in Nassau and western Suffolk Counties, and finally to the rural areas in eastern Suffolk County. The present (2010) population density on Long Island ranges from very dense in the western part to sparse in the eastern parts (figure 4). The population of Suffolk County has more than doubled from 1960 to 2010 however, from 1990-2010 the average rate of increase was about 70,000 per decade (figure 3E). In 1980 the population of Suffolk County surpassed that of Nassau County. The second largest concurrent decadal increase occurred between 19 when the population increased over 61%. The population of western Suffolk County began to increase markedly from 1950 to 1960 and increased over 141%. In 1980, the population in Nassau County decreased over 7% and from 1990-2010 the average rate of increase was about 6,000 per decade. As a result, the population of central and eastern Nassau County increased rapidly in the mid 1950's. The wave of suburban expansion, characterized mainly by large-scale developments of single-family homes, has been moving eastward with time.
