In response to the NIST decision, the U.S. Census Bureau announced that it would replace the FIPS 6-4 codes with the INCITS 31 codes after the 2010 Census, with the Census bureau assigning new codes as needed for their internal use during the transition. The Census Bureau decided that, based on decades of using the terminology FIPS to describe its codes, it would continue to use the FIPS name for its updated codes, where FIPS now stood for FIP "Series", since there no longer existed an official FIP "Standard".[3]
