The civic core is shrinking. There has always been a civic core, and Paul is an expert in this area. The civic core is made up of the people who are engaged in contributory behaviour in the civic sphere in multiple ways. We are seeing that the civic core is itself shrinking, so that 9% is down from where it was before.
I'm sure you could give the number, but I would guess it was 12% or something like that in the 1990s.
