Tips and FAQs

The General Laws of Massachusetts mandate an annual street listing of residents as of January 1st each year (M.G.L. ch. 51 § 4). The Cambridge Election Commission sends out census forms to every household in Cambridge each year, at the end of January or beginning of February. Forms are due back to our office within 10 days. The census form asks for your name, date of birth, occupation, and nationality if not a US citizen.
