INDUSTRIAL DEVELOPMENT 



Table IV. 3. 2 gives a general picture of the extent of industrial 

 development in the estuarine zone. The coastal counties have 

 within their borders 40 percent of all manufacturing plants in the 

 United States, thus closely paralleling population concentration 

 into the estuarine zone. The mixture of manufacturing types in the 

 estuarine zone 1s the same as the national composition with only 

 minor exceptions, such as the concentration of the apparel manufac- 

 turing industry in the Middle Atlantic region, particularly in the 

 New York area. Distribution of manufacturing types among the bio- 

 physical regions shows regional differences related to historical 

 development as well as raw material and market availability. 



Over half of all plants in the coastal counties and one-fifth of all 

 manufacturing plants in the United States are located in the Middle 

 Atlantic biophysical region, which was the historical center of the 

 Nation's industrial growth and is still one of the major market 

 areas. The Pacific Southwest is the major industrial center of the 

 Pacific coast, and its tidal shoreline now has the same intensity 

 of development as that of the Middle Atlantic region. Some 

 industrial development in other regions tends to follow historical
