This study investigated the sociodemographic determinants of school attendance in Mauritania. Data were drawn from the National Household Survey 2019 and a logistic regression econometric model was used to analyse the association between sociodemographic variables and the dependent variable outcome: school attendance. The findings revealed that sociodemographic determinants significantly influence school attendance in Mauritania. The article highlights that males have higher odds of attendance than females, while an increase in age decreases the odds of attendance. Additionally, having a phone and national identification is associated with higher odds of attendance. Living in rural areas decreases the chances of school attendance and being of foreign nationalities has varying effects on attendance. The study provides valuable insights into the challenges of ensuring education access for all in Mauritania and recommends further research and policy interventions to address these challenges.
