As you said, each row is for one Output Area (smallest unit of census data). A Lower Layer Super Output Area contains a small number of Output Areas, which is presumably what you're seeing in column 9. > You'd have to order the free CD of boundaries but I think My Society > already uses output areas or something similar in its work. The boundaries for Output Areas are available from ONS as per the previous thread, yes. We don't use Output Areas anywhere currently, no. It also lists councils and wards (presumably as of 2001 census, or perhaps 2003-04ish), so results could be aggregated within them.
