The Covid-19 lockdown has underscored the role that neighbourhoods play in mental health and wellbeing. Neighbourhood characteristics like overcrowding, greenspace, deprivation, and social fragmentation create very different lockdown experiences, even between neighbours living streets apart. This project will investigate the role of neighbourhood conditions in mental health during the covid-19 lockdown. First, we will examine associations of urbanicity, greenspace, deprivation, and social fragmentation with participants’ symptoms of anxiety and depression during and after lockdown. Second, we will control analyses comprehensively for confounds such as poverty using propensity score matching. Third, we will examine the interplay between neighbourhood conditions and individual-level factors including age, housing, household composition and garden access in terms of mental health responses to lockdown.
