Steve - thank you! My work on human rights and justice analytics has found a great deal of unevenness in the content and quality of data from government sources. I can never say enough good things about the Census Bureau and the Bureau of Labor Statistics (BLS), who are a lynchpin of human rights and justice analytics. While many other government agencies do excellent work, the data from some is less helpful. This may be only my personal experience, attributable to my markedly limited abilities, but I have found Justice Department data both incomplete and difficult to use. As one example, research into the economic conditions under which human trafficking flourishes - supporting the identification of undetected centers of activity - is helped by regressors from Census and BLS but hindered on the outcome side of the models by poor Justice Department data. You can be sure they will be hearing from me.
I encourage others working with federal government data to use this links Steve Pierson has provided to let the office of the Chief Statistician know what is working and what needs to be improved!
