Working Papers - U.S. Census Bureau
"As the amount of data available to us expands at a dizzying pace, the demand for reliable, timely and objective analysis of the data is growing even faster. Our researchers produce papers, speak at conferences and contribute to their fields of expertise on subjects as varied as our economy and society: health, crime, income, education, housing conditions, productivity, innovation, entrepreneurship, and more. Underpinning our data products is research on the statistical methods we use to collect it.
U.S. Census Bureau "Working Papers" have not undergone the review and editorial process generally accorded official Census Bureau publications. These working papers are intended to make results of Census Bureau research available to others and to encourage discussion on a variety of topics."
