Mapping socioeconomic vulnerabilities across the EU to inform European climate risk assessment

In a new addition to the Atlas of Demography - an interactive tool by the European Commission's Joint Research Centre (JRC) - IIASA researchers (as part of the SPARCCLE project) have released an in-depth analysis of regional variations in socioeconomic vulnerability across the EU, highlighting how demographic, health, and socioeconomic factors shape the capacity of populations to withstand climate extremes.

Focusing on vulnerability indicators such as age, health, economic status, and housing conditions, the analysis reveals that vulnerability levels differ significantly depending on the degree of urbanization. Urban and rural areas offer varying levels of protection, which depend on the country and the specific type of vulnerability considered.

"Rural areas, particularly in Eastern and Southern Europe, are expected to be hit hardest by climate change. With older populations, higher rates of chronic illness, and lower income levels, these regions face greater risks from immediate climate events like floods and heatwaves, which also weaken their long-term resilience," says Anne Goujon, socioeconomics lead in the Horizon Europe-funded SPARCCLE project and Program Director of the IIASA Population and Just Societies Program.

In regions with significant aging populations, the combination of physical frailty and socioeconomic challenges exacerbates vulnerability, expected to make adaption efforts more difficult. Additionally, areas with poor health indicators, particularly those with high rates of chronic diseases, are less equipped to respond effectively to climate hazards, while low-income households face significant barriers to recovering from extreme climate events.

The findings underscore the need for targeted policies that address the specific vulnerabilities of different demographic groups and regions, ensuring that protective measures are appropriately tailored to the unique needs of each community. Addressing these vulnerabilities requires targeted interventions that consider the unique demographic, health, and economic contexts of each region, thereby ensuring that the most at-risk populations are supported in building resilience against the escalating threats of climate change.
