The article is dedicated to the study of the rates of claims and recognitions of musculoskeletal occupational disorders based on the Inail data and emerging related inequalities. The first paragraph is focused on the construction of the dataset and the second shows the calculation of the incidence of the aggregate complaints from production sector (Ateco) and province. The third paragraph analyzes the relationship between Ateco and the province in determining the course of the complaint. In the fourth paragraph the influence of Province and Ateco is analyzed in relation to social, economic and institutional phenomena. The fifth paragraph investigates the probabilistic influence regarding the recognition of occupational diseases in the employment sector, province, and pathology. The study shows a general framework of underestimation of the phenomenon, where institutional distortions arise and generate inequalities: in determining a claims or a recognition, being resident in one territory is more valuable than the related employment sector.
