Total Anime Statistics

[zebediah49]

Does anyone have any references for very broad statistics on anime? This is out of curiosity, but I can't find any numbers for "series published", "average series length", "total hours of anime ever producted", etc.

It would be more preferable to find a master list of everything, in which case I could gather these myself, but I haven't, found one. I know I could scrape AP for something close, but AP is both not authoritatively complete, and that's mean on the servers. If nobody can find anything good I suppose I'll use wikipedia's http://en.wikipedia.org/wiki/Categor..._first_release , but it'd be preferable to not have to.

I thought there was a pseudo-user on AP whose purpose was to have all anime checked off as 'watched', to act as a counter, but I can't even find that again.

Any thoughts/sources/etc?

Thanks a lot, that's quite useful. I'd still like to find epic stats of epicness, but that gives me a lower bound on total duration/count. It also compares interestingly, because wikipedia's list has 3.5K, not counting movies, and probably grouping relations together (?), compared to AP's 4.5K.

My database senses were tingling, so I decided to comment. With the amount of titles on AP, it would take a while to input all the data... very long, depending on how many parameters you want...

Or, you can assume that most anime seasons are 12-14 episodes long, and each episode is around 24 minutes long. So, one season is approximately... 288 - 336 minutes long. After that, you just need to determine the average number of seasons an anime runs. *thumbs up*

As for the other stats, you'll need to spend a few... weeks inputting all the titles (or somehow get data entry people to do it for you).

OK, so this might be considered overkill, but I borrowed acess to a friend's collection. It's somewhere around 400-450 series; I didn't really feel like counting (the arrangement makes it difficult to count automatically). This seems close enough to the other numbers (WP and AP's 3.5-4.5K) to figure as "roughly 10%", for the purposes of estimating everything.

Anyway, it was time to invoke the power of linux. Of the 10K files he has, 6.8K register as the MIME type video/*. Throwing them through `ffprobe` followed by a bit of `grep`ing yields a set of durations. After that, it's just strait up statistics:
Total Duration: 3 months 28.80 days
Average Duration: 25 minutes 12.68 seconds
Standard Deviation: 10 minutes 53.31 seconds


However, subsampling between 20 and 30 minutes, we get 6.3K surviving files, with stats
Total Duration: 3 months 15.41 days
Average Duration: 24 minutes 5.39 seconds
Standard Deviation: 64.67 seconds


Anyway, it would be reasonable to guess from this that there is around 40 months of anime around, spread across 70,000 episodes. This estimate matches nearly perfectly against EverythingWatched's "3 years 4 months" of anime.

EDIT: Next I just have to figure out some way of determining episodes/series... The strait-up average of 15 ep/series doesn't really work, because most are some multiple of a half-season, but that's offset by a lot of movies and OVAs. That data will be a lot harder to do.
