Investigating the measurement properties of livability: a scoping review

Connecting evidence-based public health recommendations to livability, a popular and relatable construct, can increase the policy relevance of research to improve community design. However, there are many different definitions and conceptualizations of livability and little consensus about its measurement. Improved measurement, including standardization, is needed to increase understanding of livability's influence on health and to facilitate comparisons across contexts. This study sought to review existing livability measures, how they were created, and evidence regarding their reliability and validity. A scoping review of three databases (PubMed, Google Scholar, and Web of Science) identified 744 eligible studies. After screening, 24 studies, 15 from the original search and 9 through backward citation searches, were included in the review. Most studies were carried out in an urban context. There was minimal consensus across studies on the conceptualization of livability. However, measure domains and indicators overlapped significantly. While the process used to validate the measures varied, most studies reported high levels of reliability and found that livability was correlated with similar measures (e.g. place satisfaction, neighborhood safety, and sense of place) and self-reported health and wellbeing. Further research is needed to develop parsimonious, standardized measures of livability in order to create and sustain livable communities worldwide.
