One of the subcategories used by the WEF is the prevalence of organised crime — listed under the "security" index. Extortion, racketeering, theft, violence, and property damage are all factors that could hold back a country's development.
To make the comparisons more reasonable, we only took countries from the Organisation of Economic Cooperation and Development (OECD). There are 34 nations, all democracies with mixed or market economies. The group is often though of as a rich countries' club.
We thinned the list down to any OECD countries that fell outside of the top 50 places in the WEF's ranks. The lower the WEF ranking given, the worse the country is for organised crime.
11. Japan — Despite their famous Yakuza gangs, Japan only just sneaks onto our list, coming in 57th place. The group is known as one of the biggest single organised-crime syndicates in the world.

8. Hungary — Like many other countries under former communist systems, Hungary experienced a surge in organised crime in the 1990s, as gangs sought to capitalise on the lack of order and the sudden emergence of massive commercial activity.
