Hollywood, a northern district of Los Angeles, California, is one of the leaders in motion picture production. The world's first commercial motion picture exhibition was given in New York City in 1894, using Thomas Edison's Kinetoscope. Since the early 20th century, the U.S. film industry has largely been based in and around Hollywood, although in the 21st century an increasing number of films are not made there, and film companies have been subject to the forces of globalization.
Accounting for 4.24% of the global population, Americans collectively possess 29.4% of the world's total wealth, and Americans make up roughly half of the world's population of millionaires. The Global Food Security Index ranked the U.S. number one for food affordability and overall food security in March 2013. Americans on average have more than twice as much living space per dwelling and per person as European Union residents, and more than every EU nation. For 2017 the United Nations Development Programme ranked the United States 13th among 189 countries in its Human Development Index and 25th among 151 countries in its inequality-adjusted HDI (IHDI).
More InfoThere were about 578,424 sheltered and unsheltered homeless persons in the US in January 2014, with almost two-thirds staying in an emergency shelter or transitional housing program. In 2011, 16.7 million children lived in food-insecure households, about 35% more than 2007 levels, though only 1.1% of U.S. children, or 845,000, saw reduced food intake or disrupted eating patterns at some point during the year, and most cases were not chronic. As of June 2018, 40 million people, roughly 12.7% of the U.S. population, were living in poverty, with 18.5 million of those living in deep poverty (a family income below one-half of the poverty threshold) and over five million live "in 'Third World' conditions." In 2016, 13.3 million children were living in poverty, which made up 32.6% of the impoverished population. In 2017, the U.S. state or territory with the lowest poverty rate was New Hampshire (7.6%), and the one with the highest was American Samoa (65%).
More InfoThe invention of the transistor in the 1950s, a key active component in practically all modern electronics, led to many technological developments and a significant expansion of the U.S. technology industry. This, in turn, led to the establishment of many new technology companies and regions around the country such as Silicon Valley in California. Advancements by American microprocessor companies such as Advanced Micro Devices (AMD), and Intel along with both computer software and hardware companies that include Adobe Systems, Apple Inc., IBM, Microsoft, and Sun Microsystems created and popularized the personal computer. The ARPANET was developed in the 1960s to meet Defense Department requirements, and became the first of a series of networks which evolved into the Internet.
More InfoThe United States often opposed Third World movements that it viewed as Soviet-sponsored, and occasionally pursued direct action for regime change against left-wing governments, even supporting right-wing authoritarian governments at times. American troops fought communist Chinese and North Korean forces in the Korean War of 1950–53. The Soviet Union's 1957 launch of the first artificial satellite and its 1961 launch of the first manned spaceflight initiated a "Space Race" in which the United States became the first nation to land a man on the moon in 1969. A proxy war in Southeast Asia eventually evolved into full American participation, as the Vietnam War.
More InfoThe United States played a leading role in the Bretton Woods and Yalta conferences with the United Kingdom, the Soviet Union, and other Allies, which signed agreements on new international financial institutions and Europe's postwar reorganization. As an Allied victory was won in Europe, a 1945 international conference held in San Francisco produced the United Nations Charter, which became active after the war. The United States and Japan then fought each other in the largest naval battle in history, the Battle of Leyte Gulf. The United States worked on a secret project, known as the Manhattan Project. They eventually developed the first nuclear weapons, and tested them in the Jornada del Muerto desert about 35 miles (56 km) southeast of Socorro, New Mexico. This was known as the Trinity Test. The test was successful, which eventually led to the bombing of Japanese cities Hiroshima and Nagasaki; the Japanese surrendered on September 2, ending World War II.
