Libraries have always played a major part in promoting enumeration efforts, hosting more than 6,000 Census outreach sites for the 2010 Census, according to the American Library Association. But their role could be even larger this time, given that the federal government is shifting to online enumeration, opening about half as many area Census offices as in 2010. Library staff could offer assistance at kiosks, or patrons will follow prompts after they log in to computer systems directing them to complete the online form.
