Abstract Background Veteran suicide remains a major public health concern; rates increased 64.3% from 2001 to 2022 and substantial geospatial variation exists, with state-level rates ranging from 15.4/100,000 (Maryland) to 87.1/100,000 (Montana). Surveillance of suicidal ideation (SI) and suicide attempts (SA) can provide insights to reduce suicide risk within communities. Methods A population-based, cross-sectional survey of 17,949 Veterans residing in all 50 U.S. states, the District of Columbia, Puerto Rico, and U.S. Pacific Island (PI) Territories, was conducted in 2022 to assess SI and SA prevalence. Lifetime and post-military SI and SA and past-year SI prevalence were estimated by Census region, division, and state. Prevalence ratios were calculated for post-military SI and SA to assess differences by division, accounting for demographic covariates (i.e., age, race, gender, rurality, and time since military separation). Methods used in lifetime SA and considered in past-year SI were also examined by region. Results The West had the highest prevalence of lifetime (36.94%; 95%CI = 34.65–39.23) and post-military SI (28.73%; 95%CI = 26.51–30.96), significantly higher than all other regions except for PI Territories and Puerto Rico. PI Territories had the highest prevalence of past-year SI (15.68%; 95%CI = 10.91–20.44) and lifetime (9.86%; 95%CI = 6.36–13.37) and post-military SA (5.67%; 95%CI = 3.21–8.14). At the divisional level, the Pacific West (29.12%; 95%CI = 26.01–32.23) and West South Central (29.09%; 95%CI = 26.18-32.00) divisions had the highest prevalence of post-military SI, while West South Central had the highest prevalence of post-military SA (6.89%; 95%CI = 5.07–8.70), and the PI Territories remained highest for lifetime SA. After adjusting for covariates, numerous significant differences across divisions were observed. Differences in suicide methods considered and used were also observed across regions. Conclusions Variability in SI and SA prevalence among Veterans at state, divisional and regional levels supports the need for nuanced surveillance efforts, along with targeted prevention efforts in areas at greatest risk.
