The Credit Slips blog always has tried to offer perspectives from many different social sciences. That is why many readers may be distressed to learn of the attack on the American Community Survey (ACS). If you do not do a lot of social science work, you may not be familiar with the ACS. It is an arm of the Census Bureau that provides all sorts of information about what is happening in the United States. For example, did you know that people with a college degree live, on average, about two minutes further away from their workplace? At 30 MPH, that would be one mile further away. This small fact from the ACS, which we use as an example in our empirical methods book, might tell us a lot about the structure of cities and social stratification. And, this example is a poor one because it undersells the important data in the ACS on everything from income to drug use. I have used the ACS in my work to get information on consumer financial conditions in various states. There are all sorts of uses for these data in governmental, academic, and business circles.
