Slightly different personal data point from my guiri perspective living in Barcelona I'd say that of the 12-15 Catalans that I know well the clear majority are pro independence.
Seems polls have between 60-80% of Catalans want independence : http://www.independent.co.uk/news/world/europe/poll-finds-th...

As the urban region of Barcelona has around 5 million residents (7.5 million in Catalunya) the urban areas do have a lot of support for the movement.
