People can handle typing their birth year. Just put a regex on it to ensure that it's 4 digits and falls within a reasonable date range. Don't bother to ensure that it's more than 18 years ago—things get fuzzy with voting in primaries (17-year-old can vote in primaries if they'll be 18 by the election), so best to keep it simple.
