*The high standard deviations are mainly caused by high scores of 1:VVD, 2: RPF, GPV and SGP (and also CDA), 3: CDA (mainly Catholic municipalities).
As a first step the difference between local and national results (in %) was calculated for every party that won a seat in the Second Chamber, for every municipality or province. Also the results for AOV/Unie55+ was used, because the party was so close to a seat.
However, the results for two other parties, CD and Nederland Mobiel, have not been used because they were not on the ballot in every electoral district.
Consequently the standard deviation of these resulting "group of differences" has been calculated for every municipality, and rounded on 4 decimals. The lower the standard deviation, the lower the deviation from the national result, 0 is an exact match.
