People in vulnerable situations are disproportionately affected by climate change. Nonetheless, the majority of available climate-related multidimensional vulnerability indicators and assessments are at the national or regional level, with individual and household level disparities not being fully considered. The objectives of this paper are twofold: first, the authors analyse climate-related multidimensional vulnerability measurements, focusing on individual and household characteristics in Ghana, Kenya, and South Africa; second, they examine the psychometrics analyses of the indicators to evaluate their reliability and validity in terms of measuring multidimensional climate-related vulnerability across the three countries. The multidimensional vulnerability analysis demonstrates that poor and rural households are more likely to be vulnerable to climate-related impacts in all three countries. Although the primary indicators driving overall multidimensional vulnerability varies among the three countries, employment type, access to basic services, food insecurity, and demographic factors are all important factors in the three countries. The psychometrics analyses of the indicators demonstrated that lack of access to safe water and sanitation and food insecurity were reliable and valid climate vulnerability indicators across the three countries.
