The Population Reference Bureau created the KIDS COUNT Data Resource Guide to facilitate the use of population data from the U.S. federal statistical system. "Originally designed for the KIDS COUNT program on child well-being, the guide offers practical advice on how to use major data sources—from the Decennial U.S. Census to the National Vital Statistics System—that could be helpful to anyone who works with U.S. population data.
"The guide includes an overview of each major data source, including what data are available, how to access that data, and some best practices for using each source. These sources provide up-to-date and reliable information that is comparable across all 50 states, the District of Columbia, and, where available, Puerto Rico and the U.S. Virgin Islands."
