Ancestry has long had the largest collection of genealogy data online being an early leader in subscription based genealogy. Because of its extensive census images and indices, and its World War 1 Draft Cards, it has the best collection at this time too. Its census images presently cover all available federal US records, and contains extensive census images from Canada, UK, Scotland, and Germany. This is a subscription based service, however you can access the databases for the next 14 days for free by using their Free Trial at Ancestry offer.
