Unusual among modern urban neighbourhoods, Sandy Hill demographics change dramatically within a few blocks. Very wealthy people live near the embassies of the Rideau River, but closer to the university, one finds more students, senior citizens, and new immigrants with more diversified income levels. Housing in the western end of Sandy Hill includes boarding houses, student rental housing, modest privately owned homes and cooperative housing. For example, on Henderson Avenue, a historically Irish working-class sector of Sandy Hill, there are two Housing Cooperatives: Sandy Hill Housing Co-op and St. Georges Housing Cooperative / la Coopérative d'habitation St Georges, a bilingual, multicultural coop, with residents who come from Canada, with neighbours newly arrived from Ghana, DR Congo, Morocco, Rwanda, Burundi, Poland and several Middle Eastern countries. These Coops not only provided attractive low-rise multi-housing mixed income communities but also contributed to the restoration of the heritage homes on this street and won awards for their contribution to Sandy Hill's heritage restoration.
