Abstract Background Our group has previously demonstrated that low socioeconomic status (SES) independently predicts ≤ 25th percentile weight-loss following bariatric surgery (BS). Given that sociodemographic metrics can be separated into income, education, and race, we sought to investigate how each metric independently impacted weight loss following BS. Methods Patients from a single academic institution who underwent bariatric surgery from 2014 to 2016 were retrospectively reviewed. Patients were stratified by income (low/high), education (≤ high school/ ≥ college), and race (black/white) then compared using univariate analysis. Variables significant on univariate analyses were subsequently used for a greedy 1:3 propensity score match with a caliper of 0.2. After matching, groups were balanced on demographics, social/medical/ psychological history, and surgery type. Percent excess body weight loss for each post-operative time point was compared using appropriate univariate analyses. A p-value ≤ 0.05 was considered statistically significant. Results 571 patients were included. Unmatched race analysis demonstrated black patients were significantly younger (p = 0.05), single (p
