Voters have weighed in on a wide range of ballot measures, shaping policies at both the state and local levels. Across more than a century, ballot measures have addressed governance, taxation and budgets, elections, criminal justice, education, transportation, social issues, environmental policy, and more.
Some of the most significant changes to state government structures and policies have occurred through ballot measures, including changes to tax structures and electoral systems. In some cases, ballot measures also preceded or contributed to broader national policy changes and conversations, such as women’s suffrage, prohibition, and lowering the voting age.

- History of right to hunt and fish constitutional amendments: Between 1776 and the mid-1990s, there was just one state—Vermont—with a state constitutional right to hunt and fish.

- History of same-sex marriage ballot measures: The ballot measure played a significant role in shaping the legal status of same-sex marriage in the U.S. before Obergefell v. Hodges (2015). Between 1994 and 2023, voters in 30 states approved 34 ballot measures to prohibit same-sex marriage or define marriage as between one man and one woman. While Obergefell rendered these ballot measures—most of which are constitutional amendments—unenforceable, the measures remain part of state constitutions, and several states have addressed ballot measures to repeal them.
- History of women's suffrage ballot measures: Before the 19th Amendment, the women's suffrage movement also campaigned for changes to state constitutions to provide women with a right to vote.

Fifteen (15) of the ballot measures were approved, giving women the right to vote in 15 states. Since women did not have suffrage until after the ballot measures were approved, male voters decided the outcome of suffrage ballot measures.
