This report takes stock - mid 2021 - of the (scientific) knowledge about the impact of the Covid-19 pandemic on vulnerable groups, with a focus on homeless people, migrants, Roma, people with disabilities and vulnerable children. A distinction is made between primary, secondary and tertiary impact. Although the covid-19 crisis is undoubtedly bigger than the financial crisis of 2008 – and so is the risk of social damage – EU and national governments have drawn lessons from the past and adopted much more cautious and protective policy measures. Nevertheless, - the main risk of the covid-19 crisis is that it will once again amplify socioeconomic inequalities, both directly (through the impact on income and employment) and indirectly (through the unequal harm to people’s health and children’s education); - Social protection systems have so far played a very important role as ‘built-in stabilisers’. Further improvements remain necessary, to meet the needs of increasing numbers of atypical workers such as platform workers, and to guarantee a waterproof protection for all, including measures to integrate those who were trapped in the informal economy. - • The covid-19 crisis has demonstrated the need to invest in resilient healthcare systems. While some countries managed very well to cope with successive waves of the pandemic, in other countries the past austerity measures had undermined the national healthcare systems to the point that hospitals were overwhelmed, regular care was often downsized, and thousands of lives were avoidably lost. Strengthening the capacity of the healthcare systems should not only focus on the hospital sector, but particularly also on primary care. The crisis also revealed a glaring lack of affordable mental health care, and even preventive healthcare and protective equipment for other service providers. - • Another important lesson from the pandemic is the link between housing and health – and more generally, the indivisibility of fundamental rights. The higher risk of contagion among homeless people, migrants, Roma and even people living in institutions is due to a large extent to overcrowding and/or low-quality accommodation. Large-scale investment in decent and affordable housing will prevent a lot of health problems in the future (not just in relation to pandemics, but also to chronic diseases and mental health issues). From the perspective of fundamental rights, the health impact of housing exclusion even calls into question the exclusion of undocumented migrants from the right to housing. - • The shock effect of the covid crisis has disrupted public and social services that are important for the general population but indispensable to vulnerable groups, especially during the first wave: daily support to people with disabilities, mental health services, family counselling, learning support to children at risk, etc. This has enhanced the vulnerability of those groups and the social damage of the crisis. Better preparation for future shocks, through legal intervention, sufficient staffing and preventive measures can help to avoid that vulnerable people bear the brunt of such shocks. - • Our methodological framework distinguished between primary, secondary and tertiary impact analysis. Strikingly, the secondary impact of the covid-19 crisis has affected different groups and is much more multidimensional, compared to the primary impact. As regards the tertiary impact, the analysis unavoidably remains somewhat speculative, but it suggests that ‘nothing will return to normal’ unless powerful recovery measures are taken. The children of the ‘corona generation’ risk incurring severe scars in terms of mental health and educational and future labour market outcomes. This awareness emphasises once again the importance of long-term thinking, thorough social impact assessment methods, and a genuine ‘investment’ perspective in social policies. - • Finally, the crisis revealed the lack of essential monitoring data. Even the scientific emergency programmes to examine the impact of covid-19 on the population have largely overlooked the most vulnerable groups. Reliable and timely monitoring data are no luxury: they are essential inputs for swift and effective policy responses and can help save thousands of lives. ispartof: The impact of the COVID-19 crisis on vulnerable groups in the EU status: published
