Gun ownership has declined over the past 40 years — but almost all the decrease has come from Democrats. By 2010, according to the General Social Survey, the gun ownership rate among adults that identified as Democratic had fallen to 22 percent. But it remained at about 50 percent among Republican adults.

White voters were substantially more likely to own guns than Hispanics, blacks or Asians. But white Republicans were more likely to own guns than white Democrats, Asian Republicans more likely than Asian Democrats, and so forth.
