"This paper reports estimates of the relative and absolute sizes of the coastal population in the United States in the years 1990, 2000, and 2010. The estimates vary greatly among states in both the rate and direction of change, with increases expected for most marine coastal states and declines for most states bordering the Great Lakes. Together, only about 52.9 percent, 53.3 percent, and 53.6 percent of the United States's population is predicted to live in counties entirely or substantially within 50 miles of coastlines in the years 1990, 2000, and 2010, respectively. The need for long-range planning is not diminished, however, since the absolute size of the coastal population is estimated to increase to nearly 143 million people by the turn of the century."

对沿海地区未来人口变化的估计

“这篇论文报告了 1990 年、2000 年和 2010 年美国沿海人口的相对和绝对规模的估计。各州之间的估计变化速度和方向差异很大，预计大多数海洋人口会增加。沿海州和与五大湖接壤的大多数州的下降。预计在 1990 年和 2000 年，只有大约 52.9%、53.3% 和 53.6% 的美国人口居住在完全或基本上距离海岸线 50 英里以内的县和 2010 年。然而，长期规划的需求并没有减少，因为到世纪之交，沿海人口的绝对规模估计将增加到近 1.43 亿人。”
