Despite criminal careers comprising events in which offenders co-offend with others, we know less about the extent of co-offending groups showing signs of becoming specialists. To start addressing this gap, in this study we report a method through which we identified 1,796 co-offending groups in a network containing information about adult offenders (n = 76,697) connected to criminal investigations (m = 35,604) between 2010 and 2018. During this timeframe, one in five co-offending groups remained unchanged in their composition and re-offended. Of those re-offending, 54% became specialists in crimes such as those affecting private property. The other 46% that re-offended were generalists. Simulation analyses showed that the proportion of highly specialised groups was not observed by chance. These results suggest that criminal specialisation is a characteristic also shared by co-offending groups. Criminologists and practitioners might find helpful the method employed here to identify co-offending groups and assess their level of specialisation. date: 2024-07-01 date_type: published publisher: Informa UK Limited official_url: http://dx.doi.org/10.1080/17440572.2024.2371326 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2291911 doi: 10.1080/17440572.2024.2371326 lyricists_name: Davies, Toby lyricists_id: TPDAV87 actors_name: Davies, Toby actors_id: TPDAV87 actors_role: owner full_text_status: public publication: Global Crime citation: Nieto, Alberto; Davies, Toby; Borrion, Hervé; (2024) Exploring criminal specialisation in co-offending groups.
