Aleks pointed me to this report by Scott Keeter of the Pew Research Center. First the quick pictures:
These should not be a surprise (given that there are tons of surveys that ask about age, voting, and party ID) but it’s interesting to see the pictures. Peak Republican age is about 46–that’s a 1960 birthday, meaning that your first chances to vote were the very Republican years of 1978 and 1980, when everybody hated Jimmy Carter.
The Pew report also had information on political participation:
As expected, the under-30s vote a lot less than other Americans. But a lot more of them try to persuade others, which is interesting and is relevant to our studies of political attitudes in social networks.
P.S. The graphs are pretty good, although for party id vs age, I would get rid of those dotted lines and clean up the axes to every 10% on the y-axis and every 10 years on x. The table should definitely be made into a graph. The trouble is, it takes work to make the graph and you wouldn’t really get any credit for doing it. That’s why we’d like a general program that makes such tables into graphs.
