That depends on whether or not economies will collapse across the globe.
If they do, or the migration pressure throws countries into war, then all bets are off. You could plausibly raise that estimate to 60-70% (entire urban population + some margin). Cities aren't self-sufficient wrt. food. Many countries aren't either. So if, for some reason, national transport and power infrastructure goes down for good, you can scratch city dwellers off the map.
