This paper uses data collected across the four waves of the National Income Dynamics Study (NIDS) to construct a measure of social cohesion for South Africa. We compare our index to one derived using the Afrobarometer data and find a large degree of consistency in trendsin the index and its constituent components over time across the two datasets. However, there is less consistency in the measures once one moves to lower levels of geographic disaggregation. We also find far less variability in the constructed index relying on NIDS panel data as opposed to the repeated cross-sections from Afrobarometer. Having derived the index, we then correlate it with a variety of indicators of social and economic well-being. We show that higher levels of education, per capita income and employment are positively associated with higher social cohesion while social cohesion is negatively associated with poverty, service delivery protest and perceptions of crime. In addition, municipal policy and competence are closely associated with higher social cohesion.  While this work is exploratory, it is encouraging, and suggests new opportunities for future research to begin to take seriously the link between social cohesion and economic and social development.
