John Samples summarizes a Pew poll, for what it is worth, that has some interesting results:

“libertarians, though the smallest of the ideological groups, represent a substantial percentage of the population.”
…Libertarians are 50 percent more likely to declare themselves “secular” than the general population. Still, only about 12 percent of the libertarians surveyed identified themselves this way. Libertarians are also more likely than the general population to identify as a “white Catholic.” Finally, almost two-thirds of the libertarians said they go to church at least once a month. That’s a little less than the general population, but a lot more than I would have guessed.
…One-third of Pew’s libertarians are between 18 and 29 years of age. Libertarians are thus fifty percent more likely to be found among the young than in the population as a whole. They are also much more likely to be found among the youngest cohort than are conservatives or populists.
