The effect of socioeconomic factors on receipt of definitive treatment and survival outcomes in non‐metastatic head and neck squamous cell carcinoma ( HNSCC ) remains unclear. Eligible patients ( n = 37 995) were identified from the United States Surveillance, Epidemiology and End Results ( SEER ) database between 2007 and 2012. Socioeconomic factors (i.e., median household income, education level, unemployment rate, insurance status, marital status and residence) were included in univariate/multivariate Cox regression analysis; validated factors were used to generate nomograms for cause‐specific survival ( CSS ) and overall survival ( OS ), and a prognostic score model for risk stratification. Low‐ and high‐risk groups were compared for all cancer subsites. Impact of race/ethnicity on survival was investigated in each risk group. Marital status, median household income and insurance status were included in the nomograms for CSS and OS , which had higher c‐indexes than the 6th edition TNM staging system (all P < 0.001). Based on three disadvantageous socioeconomic factors (i.e., unmarried status, uninsured status, median household income < US $65 394), the prognostic score model generated four risk subgroups with scores of 0, 1, 2 or 3, which had significantly separated CSS / OS curves (all P < 0.001). Low‐risk patients (score 0–1) were more likely to receive definitive treatment and obtain better CSS / OS than high‐risk patients (score 2–3). Chinese and non‐Hispanic black patients with high‐risk socioeconomic status had best and poorest CSS / OS , respectively. Therefore, marital status, median household income and insurance status have significance for predicting survival outcomes. Low‐risk socioeconomic status and Chinese race/ethnicity confer protective effects in HNSCC .
