2024 in California

The year 2024 in California involved and is expected to involve several major events.

Demographics
The population of California on January 1, 2024, was estimated to be 39,128,162, according to the California Department of Finance. The population increased by 67,000 from 2023, the first rise in population since 2020. The Los Angeles Times attributed the increase to changes in domestic migration across states, a decrease in deaths to pre-COVID-19 pandemic levels, and U.S. president Joe Biden's immigration policies.

Conflicts
Pro-Palestinian protests occurred at California universities. In April, California State Polytechnic University, Humboldt closed its campus for the remainder of the semester.

Sports
In the 2023 NFL season, the Los Angeles Rams advanced to the Wild Card playoffs and the San Francisco 49ers advanced to the divisional playoffs. The Rams lost to the Detroit Lions 24–23, securing the Lions's first playoff win since 1992. In the NFC Championship Game, the 49ers defeated the Lions 34–33, allowing the 49ers to face the Kansas City Chiefs in Super Bowl LVIII. The Chiefs defeated the 49ers 25–22, becoming the first team to consecutively win the Super Bowl since the New England Patriots in Super Bowl XXXIX.

In March, Ippei Mizuhara, the interpreter for Los Angeles Dodgers designated hitter Shohei Ohtani, was accused of using Ohtani's funds to place bets with a bookmaker who is the subject of a federal investigation.

Media
The Los Angeles Times reduced its newsroom by 20% in an effort to reduce losses.

Economy
Significant layoffs in the technology sector as a consequence of growth during the COVID-19 pandemic continued into 2024. In January, Unity Technologies laid off 1,800 employees—or a quarter of its workforce, Amazon's live streaming service Twitch laid off 500 employees—or 35% of its workforce, and Google laid off hundreds of employees in its engineering, voice assistant, and hardware divisions that month.

National politics
In December 2023, California secretary of state Shirley Weber ruled that Donald Trump was eligible to be on the ballot in the 2024 presidential election. On July 21, 2024, Joe Biden, the president of the United States since 2021, concluded his presidential campaign, endorsing Kamala Harris, the vice president of the United States since 2021 and a former California attorney general.

Law
A law prohibiting the concealed carry of firearms in most public places took effect on January 1, 2024, after the Court of Appeals for the Ninth Circuit paused an injunction District Court for the Central District of California judge Cormac J. Carney implemented in December 2023. The Ninth Circuit ruled on January 7 that the law could not proceed.
