Significant variation in its level between and within countries suggests a relationship between social structure and the prevalence of corruption, yet, large-scale empirical studies thereof have been missing due to lack of data. In this paper, we relate the structural characteristics of social capital of settlements with corruption in their local governments. Using datasets from Hungary, we quantify corruption risk by suppressed competition and lack of transparency in the settlement\u2019s awarded public contracts. We characterize social capital using social network data from a popular online platform. Controlling for social, economic and political factors, we find that settlements with fragmented social networks, indicating an excess of<jats:italic>bonding social capital<\/jats:italic>has higher corruption risk, and settlements with more diverse external connectivity, suggesting a surplus of<jats:italic>bridging social capital<\/jats:italic>is less exposed to corruption. We interpret fragmentation as fostering in-group favouritism and conformity, which increase corruption, while diversity facilitates impartiality in public life and stifles corruption.<\/jats:p>","DOI":"10.1098\/rsos.182103","type":"journal-article","created":{"date-parts":[[2019,4,3]],"date-time":"2019-04-03T07:09:38Z","timestamp":1554275378000},"page":"182103","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":48,"title":["Social capital predicts corruption risk in towns"],"prefix":"10.1098","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9044-2018","authenticated-orcid":true,"given":"Johannes","family":"Wachs","sequence":"first","affiliation":[{"name":"Department of Network and Data Science, Central European University, Budapest 1051, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1800-6094","authenticated-orcid":true,"given":"Taha","family":"Yasseri","sequence":"additional","affiliation":[{"name":"Oxford Internet Institute, University of Oxford, 1 St Giles, Oxford OX1 3JS, UK"},{"name":"Alan Turing Institute, 96 Euston Road, London NW1 2DB, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bal\u00e1zs","family":"Lengyel","sequence":"additional","affiliation":[{"name":"Agglomeration and Social Networks Lend\u00fclet Research Group, Hungarian Academy of Sciences, Budapest 1097, Hungary"},{"name":"International Business School Budapest, Budapest 1037, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e1nos","family":"Kert\u00e9sz","sequence":"additional","affiliation":[{"name":"Department of Network and Data Science, Central European University, Budapest 1051, Hungary"},{"name":"Institute of Physics, Budapest University of Technology and Economics, Budapest 1111, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2019,4,3]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.2307\/30035860","article-title":"The persistence of corruption and slow economic growth","volume":"51","author":"Mauro P","year":"2004","journal-title":"IMF Staff Pap."},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.1353\/jod.2013.0020"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpubeco.2005.08.007"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1080\/00343404.2013.770141"},{"key":"e_1_3_6_6_2","doi-asserted-by":"publisher","DOI":"10.1257\/aer.101.5.1872"},{"key":"e_1_3_6_7_2","doi-asserted-by":"publisher","DOI":"10.1353\/wp.2006.0022"},{"key":"e_1_3_6_8_2","doi-asserted-by":"crossref","unstructured":"Guiso L Sapienza P Zingales L. 2011 Civic capital as the missing link.
