The Multidimensional Index of Bureaucratic Under-representation aims to give a snapshot of the incidence and depth of the underrepresentation in the bureaucratic aparatus of each country in five different dimensions: female/male, ethnic minorities, Non-nationals, Young people and people with disabilities.

It uses ESS microdata on the occupation of individuals, registering whether they work in the public sector (either in the central / local government or in decentralized public services such as health or education). After adjusting for the analytical weights indicated by ESS administrators this allows for the possibility to approximate comparisons between the demographic characteristics of public sector officials versus the broader country population.
