Abstract: In March of 2005, the National Oceanic and Atmospheric Administrations Special Projects Office released “Population Trends along the Coastal United States: 1980-2008” (Crossett et al. 2004). This report includes population changes and trends between 1980 and 2003 and projected changes in coastal populations by 2008. Given the findings, pressure on coastal resources around the country will continue to rise, particularly in Florida. Among the pertinent facts are these figures: • The narrow coastal fringe that makes up 17 % of the nation's contiguous land area is home to more than half of its population. • In 2003, approximately 153 million people (53 % of the nation’s population) lived in the 673 U.S. coastal counties, an increase of 33 million people since 1980. • In 2003, 23 of the 25 most densely populated U.S. counties were coastal. • By the year 2008, this year, coastal county population is expected to increase by approximately 7 million. • From 2003 to 2008, coastal population in the Southeast region is expected to grow by 1.1 million people or 8%. • Florida grew by 7.1 million people between 1980 and 2003. This number is second in the nation after California at 9.9 million people. Both of these states are far beyond Texas, the third ranked state at a growth of 2.5 million people. In terms of percent population change, these numbers represent 75 %, 52 %, and 47 % increases for Florida, Texas, and California, respectively. • Almost one quarter of the nation’s seasonal homes are found in the coastal areas of Florida and 24 % of Florida’s coastal housing is seasonal. • Of the 10 leading Southeast counties in population change, 8 are expected to be in Florida. Population growth will be most prominent in the southernmost portion of Florida, with Broward County expected to increase by 167,000 people and Palm Beach County expected to increase by 151,000 people.
