This study aimed to assess temporal, geographic, and demographic disparities in its burden across US states from 1990 to 2021.Methods: Global Burden of Disease 2021 data for all 50 US states and the District of Columbia were analyzed for 1990\u20132021. Counts and age-standardized rates per 100,000 population for prevalence, incidence, and years lived with disability (YLD) were compared by region, state, sex, age group, and sociodemographic index (SDI) level.Results: In 2021, neck pain accounted for 9,430,000 (95% uncertainty interval [UI], 7,400,000\u201311,590,000) prevalent cases, 1,900,000 (95% UI, 1,490,000\u20132,320,000) incident cases, and 920,000 (95% UI, 620,000\u20131,300,000) YLD, increases of 41.17%, 37.44%, and 38.72%, respectively, from 1990. Although age-standardized incidence increased globally by 1.18% (0.07%\u20132.39%) over 1990\u20132021, the United States had small declines in age-standardized incidence (\u22120.11%; 95% UI, \u22120.18% to \u22120.06%), prevalence (\u22120.20%; 95% UI, \u22120.32% to \u22120.10%), and YLD (\u22121.12%; 95% UI, \u22122.02% to \u22120.22%). Neck pain rates were highest in the District of Columbia, Georgia, and Delaware and lowest in North Carolina, Alaska, and Wyoming. The burden peaked at ages 40\u201349 years and was higher in females. Age-standardized YLD rates for neck pain were significantly positively correlated with the SDI (Spearman\u2019s \u03c1=0.601, P&lt;0.001).Conclusion: The geographic and demographic disparities in neck pain burden across US states indicate a need for targeted interventions.<\/jats:p>","DOI":"10.12771\/emj.2026.01270","type":"journal-article","created":{"date-parts":[[2026,10,2]],"date-time":"2026-10-02T07:35:01Z","timestamp":1790926501000},"page":"e30","update-policy":"https:\/\/doi.org\/10.12771\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
