This question does not only affect voting; but schools, taxes, public health, education and infrastructure, and more. State and local funds are often distributed based on population, meaning that every person is important when advocating for funding. The strength of census statistics and data also helps inform many public policy proposals at all levels of government.
It affects reapportionment. Without the question, some states will unfairly lose seats in the House while others unfairly gain seats. Ohio, New York, and Rhode Island will probably lose 2 seats each. Massachusetts, Pennsylvania, New Jersey, Michigan, Illinois, Iowa, Louisiana, Minnesota, and Missouri; will probably lose 1 seat each. South Carolina, Georgia, Arizona, Utah, Nevada, and Washington; will probably gain a seat. Florida should gain 2 seats. And Texas will gain 4 seats! [Note that many states who will lose seats are against the question, while some, such as TX and AZ; which will gain seats are for the question. Just goes to show that intelligence is not a common trait of governors or politicians as a general rule.]
