QPHONEORIG
Flag for Phone (original version)

Description

In November 2010, the Census Bureau released revised data for several years of the ACS due to errors. As part of this release, the data quality flag QPHONE changed. We provide QPHONEORIG so that users can analyze the differences in the revisions or replicate previous analyses. However, we recommend that users analyze the revised data quality flag QPHONE in their research. For more information about this revision, please see Erratum #64 on the ACS website.
