There is no question that Americans own more guns, and use them more often to kill each other, than citizens of any other advanced Western democracy. As of 2007, the Bureau of Alcohol, Tobacco, and Firearms reported that there were approximately 294 million guns in the United States, nearly one for every man, woman, and child in the country: 106 million handguns, 105 million rifles, and 83 million shotguns (these figures are discussed here). Though crime rates in general have been on a steady decline since the mid-1990s, according to the CDC more than 10,000 Americans are still murdered every year with firearms; add in suicides and accidental deaths, and the number exceeds 30,000.
Nevertheless, these statistics obscure a trend that has gone largely unnoticed: fewer and fewer Americans own guns. Data from the General Social Survey show that rates of gun ownership have been decreasing steadily for three decades. In 1977, 54 percent of American adults lived in a household that contained a gun. By 2010, that figure had declined a full 22 percentage points to 32 percent.
