What role do postal carriers play in census preparations? What new response category will be featured on this year's census form? Test your Census expertise on these questions and more with the Pew Research Center's U.S. Census Knowledge Quiz. The 12-question quiz covers the history, purpose, and changes to the U.S. Census and provides test-takers with answers and explanations immediately following their attempt. Readers who are displeased with their results may want to sign up for the Pew Research Center's "short email mini course" on the U.S. Census (accessible by clicking the linked text on the quiz's landing page). This free course is divided into five sections including "What is the census and why is it taken?" and "What is new – and possibly challenging – about the 2020 census?" The course is taught by D'Vera Cohn, a journalist who has studied the topic for over two decades. Enrolled users will receive "an email with a lesson every few days," allowing for a manageable way to better understand why this data collection process is so important.
