Thanks to the Scout Report for pointing out this useful blog!
The U.S. Census Bureau provides a wealth of data about the population and economy of the United States, and certain aspects of their work are covered in this eminently engaging blog, “Random Samplings”. The intent of this blog is “to describe the objective of their work and explain census and survey results”. The blog began in September 2010, and visitors can search the archive of previous posts by category or date of publication. Some of the categories include “business ownership”, “income”, and “poverty”.
