Turnout and Territorial Reform: Data from Sub municipal governments in Portugal

摘要

This database is related to the voter turnout in five election cycles (2001, 2005, 2009, 2013 and 2017). The data was used in the original in the article “The effects of amalgamations on voter turnout: Evidence from sub-municipal governments in Portugal” (DOI: ). The evolution of turnout in Portuguese sub-municipal units (SMUs) has followed the trend of western democracies and recorded a continuous drop. The 2013 territorial reform of SMUs contributed to the increment of the gap of electors that choose not to cast a vote in the elections. Data provides further details on how the territorial reform had an impact on the level of electoral participation. It also adds data on SMUs turnout divided by type and whether or not SMUs were merged.
