Data about co-production and cooperative working

We are updating our State of the Borough report, which is a digest of socio-demographic facts about Lambeth. We are considering including a section on co-production & co-operative working – is anyone aware of any data we could include? E.g. number of people involved in timebanking, no of local organisations working cooperatively, etc
