"ALA compiles data on book challenges from confidential reports filed with its Office for Intellectual Freedom by library professionals in the field and from news stories published throughout the United States. Because many book challenges are not reported to the ALA or covered by the press, the 2024 data compiled by ALA represents only a snapshot of book censorship throughout the year.
The American Library Association documented another year in an unabating deluge of efforts to censor library materials in 2024, continuing an extremist campaign to suppress access to books that began in 2021. Last year, 2,452 unique titles were challenged, the third highest number ever documented by ALA and significantly exceeding the annual average of 273 unique titles over the period from 2001–2020.
The data shows that the majority of book censorship attempts are now originating from organized movements. Pressure groups and government entities that include elected officials, board members, and administrators initiated 72% of demands to censor books in school and public libraries." - ALA

"In 2024, ALA’s Office for Intellectual Freedom tracked 821 attempts to censor library materials and services. In those cases, 2,452 unique titles were challenged. Last year, ALA tracked 1,247 attempts with 4,240 unique titles challenged. Though the number of reports decreased in 2024, the number of documented attempts to censor books continues to far exceed the numbers prior to 2020. Read the full announcement.
ALA cites the following factors contributing to the decrease in documented censorship from 2023:
New data reported to ALA’s Office for Intellectual Freedom (OIF) shows that the majority of book censorship attempts are now originating from organized movements. Pressure groups and government entities that include elected officials, board members and administrators initiated 72% of demands to censor books in school and public libraries. Parents only accounted for 16% of demands to censor books, while 5% of challenges were brought by individual library users. The 120 titles most frequently targeted for censorship during 2024 are all identified on partisan book rating sites which provide tools for activists to demand the censorship of library books.
The most common justifications for censorship provided by complainants were false claims of illegal obscenity for minors; inclusion of LGBTQIA+ characters or themes; and covering topics of race, racism, equity, and social justice." - ALA
