[Fathom] 2004 US Presidential Election Data

After a week or so of happy collaboration, I have put together an
interesting fathom dataset with county-by-county results. I have posted it
<a href=""></a>
and Bill Finzer is planning to post it to the revamped Fathom resource
center next week. I thought it might be timely to get it out on
inauguration day, though.

Be sure to have a look at <a href=""></a> and
<a href=""></a> as an introduction. The
comments tell the story and give the credit, the text box describes how to
create a fathom version of the map, and the resized collection gives you a
display of the data that helps to think about population density.

For the serious statisticians in the crowd, I have two questions:

1. If you plot the pctBlack (Black/pop2000) against the pctBush
(Bush/(Bush+Kerry+Nader)), you get a wedge-shaped graph. It is like the
maximum possible level of support for various proportions has a linear
correlation but there is lots of variation below that. Is this a typical
behaviour or does it result from some simple structure in the data that I
am missing?
2. Tim Erickson's suggestion to plot log(populationdensity) vs. pctBush to
get a football shaped cluster with negative correlation is interesting. Is
taking the log just a device to deal with the huge range or does it point
to some other important property of the data?
