Researchers reviewed quantitative studies published from 2010 to 2025, finding 18 that met their criteria for evidence from the sub-national level. The eligible studies were published between 2017 and 2025 and examined links between governance practices and trust in local governments.

Responsiveness showed the strongest and most consistent association with trust. Transparency appeared less effective when it was not accompanied by service delivery, while formal accountability mechanisms sometimes had negative associations with trust. The review found that citizen satisfaction, perceived performance and effectiveness could help explain these relationships.
