The collection of complete and accurate information in sample surveys has long been a priority, with a particular focus on non-response rates for common items like income and education. However, limited efforts have been made to incorporate and analyze non-response for questions on sexual orientation and gender identity (SOGI) in surveys, especially in developing countries such as Brazil. This study analyzes non-response rates to SOGI questions in a regional Brazilian survey, aiming to identify patterns of non-response based on sociodemographic variables. Additionally, we calculate odds ratios for non-response, considering key covariates that may influence response behavior. Our findings reveal that factors such as race and marital status significantly affect the likelihood of non-response. This research contributes to the broader national and international discourse on SOGI data collection, providing valuable insights for improving response rates and enhancing the understanding of sexual and gender minority populations.
