Key determinants of COVID-19 mortality include age, vaccination status, and sex. Districts with larger households experience higher infection ratios, while those with more highly educated residents have lower infection and mortality ratios. Districts with more non-Austrian citizens show lower case fatality ratios, likely due to younger populations. Further research into district-level age structures is warranted to refine these models. These findings underscore the importance of vaccination, particularly among older adults, and the need for accessible public health education to reduce infection and mortality ratio, especially in less-educated populations; however, district age structure (proportion of older individuals) substantially influences these associations.
