  • Data Portal New Resources

Last month’s UHC R&D team published a resource sheet with information on the census and American Community Survey (ACS) series to guide users new to these data with information about the Census/ACS and how to use the data. It explains the difference between the decennial censuses and 5-year ACS estimates and answers other commonly occurring questions about these series of datasets.

During the last month in addition to new datasets, data team made updates to some documentations. UHC data team added notes and formulas for each variable created for ACS 2005-2009 through 2017-2021 to the variable list files belonging to each dataset.
