A significant change began in 1979 when the Mandal Commission or the Socially and Educationally Backward Classes (SEBC) Commission was established to assess the situation of the socially and educationally backward classes. The commission did not have exact population figures for the OBCs and so used data from the 1931 census, thus estimating the group's population at 52 per cent. In 1980 the commission's report recommended that a reserved quota for OBCs of 27 per cent should apply in respect of services and public sector bodies operated by the Union Government. It called for a similar change to admissions to institutes of higher education, except where states already had more generous requirements. It was not until the 1990s that the recommendations were implemented in Union Government jobs. In 2019 the government announces the 10% reservation in educational institutions and government jobs for economically weaker section of upper caste category.
