Gun politics is defined in the United States by two primary opposing ideologies concerning the private ownership of firearms. Those who advocate for gun control support increasingly restrictive regulation of gun ownership; those who advocate for gun rights oppose increased restriction, or support the liberalization of gun ownership. These groups typically disagree on the interpretation of the text, history and tradition of the laws and judicial opinions concerning gun ownership in the United States and the meaning of the Second Amendment to the Constitution of the United States. American gun politics involves these groups' further disagreement concerning the role of firearms in public safety, the studied effects of ownership of firearms on public health and safety, and the role of guns in national and state crime.: 1–3  Private firearm ownership has experienced a steady increase in the United States since the turn of the 21st century, and accelerated rapidly during and following the year of 2020. The National Firearms Survey of 2021, currently the nation's largest and most comprehensive study into American firearm ownership, found that privately-owned firearms are used in roughly 1.7 million defensive usage cases (self-defense from an attacker/attackers inside and outside the home) per year across the nation. The study also found an increase in diversity amongst firearm owner demographics, reporting that rates of firearm ownership amongst females and ethnic minorities had risen sharply since the last national survey had been conducted. American gun politics is increasingly a question of demography and political party affiliation, and features well-known gender, age and income gaps according to major social surveys.
