DiversityBy 2023 More than one-half of those under 18 years of age will be non-Anglos.
By 2042 The US population is projected to be less than one-half Anglo.
By 2050, roughly 30% of the US population will be Hispanic, only slightly less than the percentage in Texas in 2000.
Diversity
By 2030,
roughly 20% of the US populationwill be 65 years of age or older, up from about 12%in 2000.

Increase in the number of household couples, despite a decrease in household size.
Households are growing in number, but the size of the family is
decreasing.
Housing
More than half of Americans
live within 50 miles of the Atlantic, Pacific, Gulf and Great Lakes on 1/5 of our land area.
By 2025, this number is expected to
increase to 75 percent.
Density
Texas, which leads the nation in population growth, had the highest number of Presidential Disaster Declarations from
1953 to 2009.
States with high vulnerability for flooding are those with floods in most years with damages exceeding
about $8 million dollars in the majority of years.
Flood Risk by State (2009)
Flood damage over $100 million dollars occurs frequently in California, Missouri and Texas, and states with the highest flood losses include
Texas, Louisiana and Florida

U.S. Flood Insurance Loss Statistics (Jan. 1, 1978 – Sept. 30, 2001)*
Socioeconomic trends, not climate change, will continue to drive increasing disaster losses
* Wharton Risk Management and Decision Processes Center
Increase in Disaster Cost *
Flood damage will continue to rise with the nation’s growing population and wealth unless actions are taken to reduce vulnerability
Suggested Future Research Target information and assistance for the most cost-effective pre- and post-disaster activities.
More in-depth analysis of trends using 2010 census data
Compare population concentration for exposure to natural disasters and develop methods of slowing the economic effects of higher concentration and density
Develop and provide communication of natural hazard risks
Develop a baseline standard of acceptable disaster vulnerability to serve as a basis for an action plan
ISO—you
deserve applause
for your work in
assessing risks,
mitigating risks
and reducing risk
across the
country.
