Instructions Remember you may work in groups on the assignment, but you must write out and turn in your own work on Canvas before the next recitation. Instructions for accessing the U.S. Census Bureau Database For the first part of the exercise we will be using the U.S. Census Bureau database on world population at the address below to answer questions on the United States of America, Niger and New Zealand: https://www.census.gov/data-tools/demo/idb/#/country?YR_ANIM=2021 A) Navigate to the webpage which looks like this: Page | 1
