Using subnational Demographic and Health Survey data from 75 low and middle-income countries, the authors show that many households lack access to decent living standards as basic prerequisites for human well-being. Major inequalities exist within and across countries and by socio-economic backgrounds.

Literature produced inconsistent findings regarding the links between extreme weather events and climate policy support across regions, populations and events. This global study offers a holistic assessment of these relationships and highlights the role of subjective attribution.
