Enterprises: number of enterprises by sector and size and corresponding number of workers by employment relationship

The dataset contains the businesses and employees surveyed in the 9th Census of Industry and Services. The survey units are: sole proprietorships, partnerships and corporations, cooperatives (excluding social cooperatives, covered by the survey on non-profit institutions), private law consortia, economic public bodies, special companies and public utility companies. For the purposes of the census, self-employed workers and freelancers are also considered enterprises. The companies are classified by Ateco 2007 (5 digits), number of workers (employees, independent, external, temporary) and their characteristics. NOTE: not all categories of workers are classified according to the same characteristics: e.g. nationality is only available for employees, profession only for employees, etc.). This dataset was released by the municipality of Milan.
