The Mapineq project focuses on the trends and drivers of intergenerational, educational, labour market and health inequalities across the life course, a core area of social, economic and policy research. A central aim of economic, social and health policy interventions is to diminish inequalities. In order to do so, we require an understanding of how inequalities may accumulate and how they are influenced by the natural environment (e.g., pollution, temperature) at the local, regional and national level. Environmental context can operate to aggravate or diminish inequalities. This report introduces Phase 2 of the Mapineq Link geospatial environmental database, a rich open-access database with API access that researchers can use to link a multitude of geo-linked policies to their own research projects.
