After years of stagnation, median household income reached a record high in 2016 following two consecutive years of record growth. Income inequality remains at record highs however, with the top fifth of earners taking home more than half of all overall income. The rise in the share of total annual income received by the top one percent, which has more than doubled from nine percent in 1976 to 20 percent in 2011, has significantly affected income inequality, leaving the United States with one of the widest income distributions among OECD nations. The extent and relevance of income inequality is a matter of debate.
In 2017, out of the U.S. foreign-born population, some 45% (20.7 million) were naturalized citizens, 27% (12.3 million) were lawful permanent residents (including many eligible to become citizens), 6% (2.2 million) were temporary lawful residents, and 23% (10.5 million) were unauthorized immigrants. Among current living immigrants to the U.S., the top five countries of birth are Mexico, China, India, the Philippines and El Salvador. Until 2017 and 2018, the United States led the world in refugee resettlement for decades, admitting more refugees than the rest of the world combined.More Info
Capital punishment is sanctioned in the United States for certain federal and military crimes, and at the state level in 30 states. No executions took place from 1967 to 1977, owing in part to a U.S. Supreme Court ruling striking down arbitrary imposition of the death penalty. Since the decision there have been more than 1,300 executions, a majority of these taking place in three states: Texas, Virginia, and Oklahoma. Meanwhile, several states have either abolished or struck down death penalty laws. In 2019, the country had the sixth-highest number of executions in the world, following China, Iran, Saudi Arabia, Iraq, and Egypt.More Info

The military budget of the United States in 2011 was more than $700 billion, 41% of global military spending. At 4.7% of GDP, the rate was the second-highest among the top 15 military spenders, after Saudi Arabia. Defense spending plays a major role in science and technology investment, with roughly half of U.S. federal research and development funded by the Department of Defense. Defense's share of the overall U.S. economy has generally declined in recent decades, from Cold War peaks of 14.2% of GDP in 1953 and 69.5% of federal outlays in 1954 to 4.7% of GDP and 18.8% of federal outlays in 2011.More Info
