Abstract:
This paper presents the first systematic analysis of regional wealth inequality in Spain. We
do so by combining administrative fiscal data with household surveys and national
accounts between 2016 and 2022. We document substantial regional disparities in both
average household wealth and its concentration. Madrid stands out as the region with the highest average wealth and top 1% wealth share. Our findings are relevant in the Spanish
institutional context, where autonomous communities exercise considerable control over
wealth taxation and public expenditure.
