Research on Jurisdictions
Political Jurisdictions – interventions which target politically distinct, but local jurisdictions. These are jurisdictions within larger geo-political jurisdictions and include cities, counties, parishes, or townships. Note that any study targeting jurisdictions is included here, regardless of the level at which the results were analyzed (e.g., micro-places, neighborhoods).
