First, the all-time stats:
Closed Closed then Edited Closed then Reopened Closed then Edited then Reopened
------ ------------------ -------------------- --------------------------------
34567 4388 1174 545
So, slightly over 3%, jumping to 12% for edited questions. For the past 365 days, we see:
Closed Closed then Edited Closed then Reopened Closed then Edited then Reopened
------ ------------------ -------------------- --------------------------------
11824 1084 263 140
Or roughly 2%, jumping to just shy of 13% again for edited questions.
The more interesting breakdown by close reason follows, again looking only at questions closed within the past 365 days:
Name Closed Closed then Edited Closed then Reopened Closed then Edited then Reopened
-------------------------- ------ ------------------ -------------------- --------------------------------
duplicate 713 49 22 10
off-topic 6257 406 103 48
primarily opinion-based 1598 187 53 29
too broad 1761 185 33 15
unclear what you're asking 1494 257 52 38
Expressed as percentages:
Name Closed then Edited Closed then Reopened Closed then Edited then Reopened
-------------------------- ------------------ -------------------- --------------------------------
duplicate 6.9 % 3.1 % 20.4 %
off-topic 6.5 % 1.6 % 11.8 %
primarily opinion-based 11.7 % 3.3 % 15.5 %
too broad 10.5 % 1.9 % 8.1 %
unclear what you're asking 17.2 % 3.5 % 14.8 %
This is mostly in keeping with what we observed on Stack Overflow, but it's worth noting that both duplicates and opinion-based questions stand a slightly better chance of being reopened, particularly if they're edited.
