The Bureau of Justice Statistics collects information on types of identity theft, such as misuse of an existing account, misuse of personal information to open a new account, and misuse of personal information for other fraudulent purposes, through the Identity Theft Supplement (ITS), a supplement to the National Crime Victimization Survey. The ITS also captures information on data breach notifications. Data breaches are events in which files or data from an entity (company, government agency, or some other organization) are stolen, lost, or posted on a publicly available website. They represent one way that personal information can be stolen. When a data breach occurs, some entities notify persons whose information was exposed to warn them of potential identity theft.

Key Findings

  • In 2021, 12% of all persons age 16 or older were notified that an entity with their personal information experienced a data breach in the prior 12 months (figure 1).
  • Victims of identity theft (24%) were twice as likely as nonvictims (11%) to learn that an entity with their personal information experienced a data breach in the past year.1
  • Victims of multiple types of identity theft (32%) were more likely than victims of existing credit card (25%), bank (16%), or email or social media account (23%) misuse to learn that an entity with their personal information experienced a data breach.

Note: Estimates are based on the most recent incident of identity theft that occurred in the 12 months prior to the interview. A data breach is an incident in which files or data of a company, government agency, or some other organization are stolen, lost, or posted on a publicly available website. In 2021, there were 263 million persons age 16 or older living in noninstitutionalized, residential settings in the United States. See appendix table 1 for estimates and standard errors.

Identity Theft Measures

Data in this report are from the 2021 Identity Theft Supplement (ITS) to the National Crime Victimization Survey. The 2021 ITS featured a redesigned questionnaire that was administered to persons age 16 or older from July through December 2021. It collected data from persons about their experience with identity theft and data breach notifications during the 12 months prior to the interview. For more information, see Victims of Identity Theft, 2021 (NCJ 306474, BJS, October 2023).
