Law No. 9.023 establishing a general guidelines for the creation of the Gross National Happiness Index (GNH) for the state of Piauí.

This Law establishes general guidelines for the creation of the Gross Internal Happiness Index of the State of Piauí (FIB-PI). Its principal objective is to provide a scientific and technical tool to support the formulation, implementation and evaluation of public policies aimed at improving happiness, emotional and mental well-being, social welfare and overall quality of life. The law authorises the State Government to develop an index capable of measuring and monitoring the well-being of the population, particularly vulnerable groups, in order to guide evidence-based public policies and interventions. The legislation seeks to promote multidimensional well-being through the collection and analysis of data relating to emotional and mental health, social and family relationships, life satisfaction, social participation, inclusion and perceptions of equality. It also allows for the development of digital platforms, mobile applications and monitoring systems to provide educational content, well-being assessments and guidance on mental health issues. The results generated by the index are intended to support public planning, preventive and educational programmes, and the identification of social vulnerabilities while respecting privacy and data-protection requirements.
