Neighbourhoods have been the site of service delivery or "service interventions" in part as efforts to provide local, quality services, and to increase the degree of local control and ownership.[10] Alfred Kahn, as early as the mid-1970s, described the "experience, theory and fads" of neighbourhood service delivery over the prior decade, including discussion of income transfers and poverty.[11] Neighbourhoods, as a core aspect of community, also are the site of services for youth, including children with disabilities [12] and coordinated approaches to low-income populations.[13] While the term neighbourhood organization [14] is not as common in 2015, these organizations often are non-profit, sometimes grassroots or even core funded community development centres or branches.
