I am currently working with US census data from 2013 at the latest. I am very interested in getting population and other demographic data pertaining to 2014 and Early 2015 as soon as possible. What approaches have people used in the past to get a sense of where the major Demographic changes are happening before the official census data is released?
NOTE: I'm interested in geographically specific information. Any information about US areas that is any less specific than the city or county level is not of any interest to me
