Provincial election results since 1993 for Bolzano-South Tyrol are now available in Elections to the South Tyrolean Landtag (Provincial Council). I have also included turnout statistics for the 2008 Landtag and Chamber of Deputies elections on The 2018 South Tyrolean provincial election, and updated the election statistics available there to fully account for the single-digit differences between preliminary and definitive 2018 vote totals.

Finally, I have corrected the correlations between voter turnout and percentage of Italian speakers at the municipal level in the 2013 and 2018 provincial elections. These were originally reported as -0.76 and -0.60, respectively, but they were actually stronger, standing at -0.84 and -0.70, respectively; the lower figures were due to the fact that five of South Tyrol's 116 municipalities had not been included in the original analysis. For comparison purposes, the correlation between voter turnout at the municipal level and percentage of Italian speakers in the 2008 Landtag election stood at -0.71 - almost identical to the corresponding figure for 2018.
