A quick analysis of some voting determinants.

[Hash]

I ran a correlation coefficient for some similar factors in France, vis-a-vis Sarko2007 by canton:

median HH income: 0.27
population density: -0.11
unemployment: -0.28
Retirees: -0.05
Ouvriers: -0.02
CPIS: 0.09
aged 60-74: -0.01

[Hash]

aged 60-74: -0.01

WHAT THE

Lots of old people in declining left-wing rural regions, such as the Limousin or the rural parts of the SW.

Anyhow, here's another strong correlation:

ouvriers and Le Pen 2007: 0.46
but...
ouvriers and Le Pen 2002: 0.23
ouvriers and FN-EXD 2010: 0.28

Amusingly stark contrast between the FN vote in 2002 and 2007, but not too surprising if you've read into the Sarkozyst OPA on the FN in 2007.
