In order to examine the social dimension of peace building as experienced by the mass public, this chapter focuses on the views of ordinary citizens towards community relations. Using a wide range of survey data, the chapter explores the nature and extent of communal divisions. The chapter addresses the question of whether or not public perceptions of relations between the two main religious (Catholics and Protestants) communities have changed since the introduction of the Belfast Agreement in 1998. It outlines the government policy in relation to community relations in Northern Ireland, with particular emphasis on the obligations of public bodies as specified in the 1998 Agreement. The chapter also focuses on the nature and extent of communal division as well as public attitudes towards greater integration. It discusses the perceptions of community relations and also examines the implications for post-conflict reconciliation.
