Wilbur Ross' proposal to ask whether a respondent is a citizen will likely result in some residents not completing their census form. As a result, we will not know how many people live where. Which will translate into how congressional seats are apportioned, how state and federal dollars are distributed, where businesses choose to ship products and where they build new stores. It would also effect the accuracy of much economic data and other statistics that businesses, researchers and policymakers depend on to make decisions, including the numbers that underpin the forecasts for Social Security beneficiaries.
It does not sound like a good idea.
