Introduction: Bariatric patients are a heterogeneous group of people. In this study we analyze social characteristics of patients undergoing primary bariatric operations to identify factors that could help predict outcomes after surgery. Methods: A single center retrospective analysis was performed on all primary bariatric operations from January 2015 to January 2017. Patients undergoing Laparoscopic Roux-En-Y Gastric Bypass (LRNYGB), Laparoscopic Sleeve Gastrectomy (LSG) and Laparoscopic Gastric Banding (LGB) were included. The social factors analyzed were: insurance status (government based vs. private insurance), marital status (married vs. not married patients), employment status (employed vs. not employed), ethnicity (Hispanic vs. white vs. non-white population). Outcomes were: Length of Stay (LOS), 30 day hospital readmissions, any complications, re-operations, follow-up rates, ∆BMI (change in body mass index), %EBMIL (Percentage of Excess Body Mass Index Loss). Results: 303 patients were included. 139 patients underwent LRNYGB (45.9%), 159 underwent LSG (52.8%), 4 underwent LGB (1.3%). As compared to those with government insurance, patients with private insurance had increased %EBWL (54.87 vs. 47.79, p=0.008) and ∆BMI (11.21 vs. 9.9, p=0.022) at the 6 month follow up visit. As compared to non-employed patients, employed patients had significantly lower rates of readmission (7% vs. 15.1% p=0.034) and complication rates (13% vs. 24.7% p=0.018). Married patients had higher rates of follow-up after 1 year compared to nonmarried patients (55.1% vs. 41.3%, p=0.017). Conclusion: Social factors can be are important outcome predictors in primary bariatric surgery that can help stratify risk and individualize perioperative management
