In the present report, methodologies used at the national level to measure the realization of economic, social and cultural rights are examined. The report starts with an overview of State obligations relating to the measurement of progressive and immediate realization of economic, social and cultural rights. The elements required to develop adequate measurement tools and indicators from a human rights perspective are then analysed. By means of the example of States’ practices, he identifies principles for an adequate human rights measurement methodology. On that basis, a number of recommendations on human rights measurement and a rights-based approach to data and statistics are made.
