The ACS: Please fill it out

The American Community Survey arrived at our house in the mail today. Well, not the survey itself, but the instructions for how to access it on line. As the envelope says, "YOUR RESPONSE IS REQUIRED BY LAW." But that's not the main reason you should complete this survey carefully, should one arrive at your address (about 1/480 chance each month). The reason is that this is the largest high-quality source of information about the U.S. population available. It covers about 1% of the U.S. population each year. I and thousands of others use the data for teaching and research: It informs reality-based policy and social science. The Census Bureau folks are real pros, and they are a lot more reliable with your information than Equifax or Target. For those of us who try to deal in facts rather than alternative facts, the ACS is indispensable. Please answer truthfully, and double-check your answers. Thanks!
