The diversity of terms and meanings relating to housing with services for older people confounds systematic analysis, especially in international comparative research. This paper presents an analysis of over 90 terms identified in literature from the United Kingdom, the United States of America, Canada, Australia and New Zealand reporting types of housing with services under the umbrella of ‘service integrated housing’ (SIH), defined as all forms of accommodation built specifically for older people in which the housing provider takes responsibility for delivery of one or more types of support and care services. A small number of generic terms covering housing for people in later life, home and community care, and institutional care are reviewed first to define the scope of SIH. Review of the remainder identifies different terms applied to similar types of SIH, similar terms applied to different types, and different terms that distinguish different types. Terms are grouped into those covering SIH focused on lifestyle and recreation, those offering only support services, and those offering care as well as support. Considerable commonality is found in underlying forms of SIH, and common themes emerge in discussion of drivers of growth and diversification, formal policies and programmes, and symbolic meanings. In establishing more commonality than difference, clarification of terminology advances policy debate, programme development, research and knowledge transfer within and between countries.
