On the Warbird Information Exchange forum, I just recently began a count of the number of DC-3's (and all related types and modified versions) that are flying world-wide, and so-far my list, which I believe is quite "exhaustive", is up to 187 (two new flyers were just added today - C-FDTD and G-ANAF, which both flew today). Several of the South American and Thailand examples are guesses based on best available information (as to their statuses at this moment), and I'm still trying to get more information on any others I'm missing in South American and African countries (it would seem that a lot of those which had been operating within countries in those continents have been retired in recent years).
