Social quality has been presented as a theory that can explain economic and social progress of the daily lives of a population. The components of social quality include: socio-economic security, social inclusion, social cohesion and social empowerment. The social quality perspective views people as interacting within collective identities that provide the contexts of self-realisation. The paper tests the social quality theory by focusing on the relationship between social inclusion and social cohesion, the notion of social relations, to socio-economic security using the context of the family as a facilitator of self-realisation. Using data from the Israel Social Survey 2003, six indicators of socio-economic security were analysed. There was a small but positive and significant relationship between social inclusion and socio-economic security. We found no relationship between socio-economic security and social cohesion. These findings tend to undermine those aspects of social quality theory which posit close connections between these elements on a conceptual level.
