I found an op-ed in the NY Times that claimed that the best way to increase voter turnout was by having election day fall on a weekend. They provide a few examples but nothing too detailed. I tried pulling in some data and seeing if I could come to the same conclusion. I used two data sets: voter turn out by country and election dates by country.
Combining this data into one table, and ignoring the missing data:
|Country||Election Type||Date||Day of week||Weekend||Turnout|
|Czech Republic||Presidential Final||Fri 2/15/08||6||No||85%|
|South Korea||Parliamentary||Wed 4/9/08||4||No||75%|
|Czech Republic||Parliamentary||Fri 10/17/08||6||No||85%|
|United States||Presidential||Tue 11/4/08||3||No||54%|
|Iceland||Presidential (Cancelled)||Sat 6/28/08||7||Yes||89%|
|New Zealand||Parliamentary||Sat 11/8/08||7||Yes||88%|
It does seem as if they are on to something - the average turnout for weekday election days was 76% while the average turnout for weekend election days was 84%. This wasn't a very rigorous examination and I am sure there are many more issues that factor in to the voting process but it does make intuitive sense.
