In this study we estimate the non-take-up rate of housing allowance in the region of Upper Austria. The analysis is based on EU-SILC 2019 data. We find that 30% of households that were entitled to housing allowances in 2018 (12,000 out of 40,000) did not claim the benefit. The non-take-up rate on the expenditure level amounts to 21%, which corresponds to 15 Mio. €. Non-take-up is particularly high among single-person households, households situated outside the regional capital Linz (statistically not significant) and households with a main earner that migrated from a third country.
