What is the Russell (NARA) Soundex Coding?
This soundex system is used by the U.S. National Archives and Records Administration (NARA). In the 1930s, the Work Projects Administration (WPA) created indexes for the 1880 (partial), 1900, 1910 (partial), 1920, and 1930 (partial) U.S. Federal censuses. Other major indexes have also used this system, such as the INS’ passenger arrival indexes.
