I think I have what you need. http://gadm.org
a) I haven't seen it all collected in one place yet (was discussing it the other day), only because I think there might be some countries where the administrative boundaries are not the same as census boundaries (very true to election boundaries). b) the long answer is only adm0 exists for all countries, particularly the small ones which tend to be islands only have 1 region. Now if you expand that a bit, adm2 exists in most countries. Census type aggregation is a primary goal of gadm. FYI, we just released gadm2.5 (this week) and are starting work on 3.0 A major new feature in 2.5 is the we have each adm as it's own layer, so you can pull up adm2 and see just how many countries have it. I actually have a bunch of interns this summer collecting and digitizing updated adm boundaries for all countries. Will make a special note to track if and what census data they might match.
