There is a sizeable body of scholarship on health inequalities and morality. What is less well covered in the literature is research which considers health inequalities and morbidity. This article specifically examines the issue of long-term illness (LTI) in the United Kingdom, which may or may not limit people’s daily activities and the work they are able to do. It poses the research question, was the propensity of LTI aggravated by the Covid pandemic? The evidence suggests that existing health inequalities associated with LTI have worsened since the pandemic. Using a multinomial logit model, the paper then computes the probability of working-age respondents to the UK-LFS having a long-term illness and, if they do, further computing the probability of this illness being limiting in either moderate or severe form. Following this, the paper computes the likelihood of a person with a LTLI having various health conditions. Lastly, the paper compares the probabilities of persons having a LTLI between 2019 and 2022 and tests whether the pandemic significantly altered these probabilities both in aggregate and for the narrower categories of population subgroups.
