Via fortune magazine. Interesting read

http://fortune.com/2014/09/14/biggest-organized-crime-groups-in-the-world/

5. Sinaloa Cartel
4. Ndrangheta
3. Camorra
2. Yamaguchi Gumi
1. Solntsevskaya Bratva

Does this sound about right? For discussion sake, who rounds out the top 10?

Kash

You should leave any information regarding OC from fortune alone. I take articles by them and any other similar site with a grain of sand.

Speaking realistically, It's all estimates at best unless the group remains exclusively small to mid size membership. The Yamaguchi gumi , despite internal division, is still the largest syndicate by membership with 30,000 or less.

Sicilian Mafia is up there.

The triads Sun Yee On, 14K and Wo Shing Wo are also huge.

It's an interesting read but I like how these magazines don't think there is a drug market in Mexico like there is in the U.S. A lot of what fuels the fire in Mexico's cartel violence is retail drug sales which cartels compete as much as drug routes and crossings. I wonder what the estimate is for the Mexican drug cartels is if you include retail drug sales from Mexico and abroad(Sinaloa Cartel in South America) in the picture. Also I thought this was a membership count and not total revenue.

Impossible to compare. The Camorra is not a single organization so it's unfair to compare it to Sinaloa, which is a much more cohesive unit compared to The Comorra..

Its very difficult compare OC groups.

I think the Ndrangehta is near at the top and much more Powerful and richer than the Camorra.

The Cosa Nostra (not the american) also under the top 10 and also the triad organisations.

How about this: 5 Largest OC groups by country?
