b'INTRODUCTION This data analysis has been prepared by RSM Economic Consulting to support the research being undertaken by the Cambridge Centre for Housing and Planning Research into shared ownership.The research draws on government data on shared ownership collected via CORE and the Statistical Data Returns (SDR). This was supplemented by a survey of shared ownership providers. The survey was distributed to shared ownership providers in England by the National Housing Federation. A total of 24 housing associations completed the survey. Between them these respondents owned 41,073 shared ownership properties in England, just under a quarter of all shared ownership homes in England. The data from the survey has been used to fill gaps in the secondary data that is available for the entire sector from other sources.THE SHARED OWNERSHIP SECTOR IN ENGLAND The size of the sector This data is taken from the 2018/19 SDR, which records data about housing association stock. In total, the SDR recorded 180,688 shared ownership properties in 2018/19.It records 246 associations as having shared ownership stock. This includes four organisations whose main focus is home ownership and whose stock is entirely this type of tenure. The large majority of the housing associations (234 of the 246) report between 1% and 19% of their stock as being shared ownership, with a further eight reporting that shared ownership makes up between 20% and 35% of their stock.
