The people of these United States 

some interesting fact from the CIA World Factbook



The population of the United States as of July 2014, was 318,892,103, making it the fourth largest country in the world.

Population growth rate: 0.77%
Birth rate: 13.42 births/1,000 population

Urban population in America is 82.4% of the total population and the largest metropolitan area is 
New York-Newark, with 20.352 million people.

The literacy rate, defined as people age 15 and over that can read and write is 99%.  The whole concept of literacy is being redefined by the computer age and it would be interesting to have a measure of the digital literacy rate.  You can find more about it on DigitalLiteracy.Gov


The United States is a highly developed and wealthy country, yet it does not rank as high as one would think in the world in terms of health statistics.

For example, the infant mortality rate: 6.17 deaths/1,000 live births, which ranks 169th in the world.  The graph below shows how we stand compared to other developed countries.










Take a look at the life expectancy at birth.  The average American lives to 79.56 years, which ranks 42nd in the world.

American Cultural Symbols






         Some of the cultural icons of the United States are recognized universally.  They are that symbols that most people envision, both in and outside the country.

The Statue of Liberty is one such example.

          The first time I saw the statue of liberty was as a child.  My family immigrated to the United States from Italy, and It was actually the very first thing I laid eyes on as the ship we were on entered New York Harbor.  We were one of the last immigrants to land on Ellis Island on a ship.

          Other symbols are things we encounter every day, for example burgers...

           I think most people would agree the burger is the quintessential American food. Kinda makes you hungry doesn't it?





          Then there are the symbols that bring to mind  many things about American heritage.  When I see a bison, I think about the American West, and the fact that once they roamed the prairies in the tens of millions  For me, the bison also symbolizes, westward expansion and the wanton abuse of our environment.

        It also reminds me of our National Parks. Once, when I visited Yellostone I woke up in my camper van surrounded by a small herd.  A mother and her calf were grazing just a few feet away. It's a memory I still cherish.
