Ballot measure topics

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.

This page provides an overview of ballot measure topics, with links to state and local ballot measure topics and historical overviews of select issues.

History of Initiative & Referendum Ballot Measures
Period: 1898 - 1996
In the U.S., 26 states have adopted constitutional amendments for citizen-initiated ballot measures. As state constitutional amendments require voter approval, except in Delaware, creating ballot initiative processes required ballot measures, either from state legislatures or constitutional convention. Most of these amendments originated during the progressive and populist movements of the 1890s to 1920s.Beginning in 1898, voters in 30 states have decided on 42 constitutional amendments to create state initiative and referendum processes. The most recent was in Mississippi in 1992, and no such amendments have appeared on the ballot since then.

The following is a list of pages that provide overviews of how ballot measures have addressed policies and topics over time, highlighting their distribution across states, the number and types of measures, and their outcomes.
  • History of ballot measures to establish initiative and referendum processes: Voters in 30 states have decided on 42 constitutional amendments to create state initiative and referendum processes. Voters approved constitutional amendments in 26 states. The average vote on a constitutional amendment to establish an initiative or referendum process was 68.3% to 31.7%. The four states that rejected constitutional amendments to establish initiative and referendum processes were Minnesota, Rhode Island, Texas, and Wisconsin.
  • History of abortion ballot measures: Since the 1970s, there were 65 abortion-related ballot measures in 30 states. From 1970 to 2024, 44 (68%) of these had the support of organizations that described themselves as pro-life. Voters approved 12 (27%) and rejected 32 (73%) of these 44 ballot measures. The other 21 abortion-related ballot measures had the support of organizations that described themselves as pro-choice or pro-reproductive rights. Voters approved 15 (71%) and rejected six (29%)
  • History of English as official language ballot measures and laws: As of 2025, 30 states had designated English as their official language. Most (27) of these states adopted their official language between the 1980s and 2000s, with a median year of 1988. Of the 30 states that designated English as their official language, 11 (37%) did so through voter-approved ballot measures. The average vote on these measures was 73.1%, with support ranging from 50.5% to 88.5%.
  • History of marijuana ballot measures and laws: The state-level legalization of marijuana began with ballot measures in Colorado and Washington in 2012. However, marijuana-related measures have appeared on ballots since 1972. Through 2024, voters have considered 83 marijuana-related ballot measures, including 33 on recreational marijuana, 32 on medical marijuana, 13 on other criminal policies, and four addressing other marijuana-related issues.
  • History of ranked-choice voting (RCV) ballot measures: The ballot measure has played a role in shaping electoral systems in the U.S., including ranked-choice voting (RCV) for state and local elections. Since 1915, there have been more than 150 ballot measures to adopt or repeal ranked-choice voting systems. From 1965 through 2024, there were 12 statewide ballot measures in eight states and 74 local ballot measures in 58 jurisdictions.
  • 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. In 1996, voters in Alabama passed an amendment, which initiated a trend. From 1996 to 2024, voters in 25 states decided on similar constitutional amendments, approving 24 of 25 (96%).
  • 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. Between 1867 and August 18, 1920, 54 ballot measures to grant women's suffrage were on the ballot in 30 states. 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.
