The study concentrates on housing vulnerability during the post-crisis period in Latvia and how it has impacted vulnerable groups, particularly seniors. Housing vulnerability includes objective and subjective factors. Seniors 65+, especially those seniors who live alone are one of the vulnerable groups in sense of housing security. It could be characterized by parameters of housing quality and housing expenses adequacy. The EU policy examines perceptions of insecurity in few areas, including housing security and old-age income insecurity – of not having an adequate income in old age. The number of single senior 65+ households is increasing in both rural and urban areas. The study explores housing vulnerability for older persons – seniors 65+, one of social groups in disadvantageous economic situation. Authors explore how housing vulnerability affects seniors, especially those who are over the age of 65+ and are living alone. The challenging issues were construction of theoretical background integrating housing security during social changes in the post-crisis period with disadvantageous situation of seniors 65+. The comparative quantitative approach is based on data from descriptive statistics. The research design is quantitative comparative analysis. To make a comparison, there were selected two groups: single seniors 65+ and all households. The proposition is that in the post-crisis period housing vulnerability for seniors 65+ was decreasing, but differs from average parameters of housing vulnerability for total population. The restriction of current study is analyses that cover only single seniors 65+. The results show significant differences in housing quality and proportional housing maintenance expenditures between single seniors 65+ and all households.
