Introduction to theme section on geographies of intellectual disability: 'outside the participatory mainstream'?

This paper introduces the following theme section on Geographies of Intellectual Disability. It outlines the historiography of geographical work on intellectual disability, noting in particular the contributions of Wolpert (Transactions of the Institute of British Geographers 5 (1980) 391) and Hall and Kearns (Health and Place 7 (2001) 237), before tracing claims made about both the 'institutional' and 'deinstitutional' eras in the changing geographies confronting and experienced by intellectually disabled people. This account, highlighting the tendency for such people to remain 'outside the participatory mainstream' in almost all circumstances, offers along the way an introduction to the four contributions that follow.
