The families differ some relatively small others very big, but you also have to know they form a locale, the main local organizational unit of the 'Ndrangheta with jurisdiction over criminal activities in an entire town or an area in a large urban center. A locale is usually made up by one clan (in the case of a small town) or several families.
Each locale has a boss, a capo locale. It has at least 49 members and besides the capo locale, there is the contabile (accountant) who handles the finances - commonly called la bacinella or la valigetta (briefcase) - and a crimine that oversees the illegal activity. All three form a triumvirate called the Copiata.
