Microfilm of original records in The National Archives, Washington, D.C.

"The Bureau of the Census created and filmed Soundex index cards for the entire 1920 census. The Soundex is a coded surname (last name) index based on the way a surname sounds rather than how it is spelled. Surnames that sound the same but are spelled differently, like SMITH and SMYTH, have the same code and are filed together. The Soundex coding system was developed to find a surname even though it may have been recorded under various spellings. The National Archives has assigned a separate microfilm publication for each state and territory. The Bureau of the Census used two separate Soundex cards, the 'family card' and the 'individual card.' Both types of cards are arranged numerically by the Soundex code and then alphabetically by the first name of the head of the household on the family cards and the first name of the individual on the individual cards."

SAMPLE FAMILY CARD The family card is arranged by the name of the head of the household. . . SAMPLE INDIVIDUAL CARD The individual card gives the names of people other than those in the immediate household (husband, wife, son, daughter) that are enumerated with a family. These include grandparents, cousins, boarders, and servants. The card also shows the name of the head of the household or the institution name where the person is living. The information on the Soundex card includes the surname, first name, state and county of residence, city (if appropriate), age, place of birth, and whether a U.S. citizen. Each card also lists the volume, enumeration district, sheet number, and line number where the person can be found on the population schedule.

SOUNDEX CODING GUIDE The number Represents the letters 1 B,P,F,V 2 C,S,K,G,J,Q,X,Z 3 D,T 4 L 5 M,N 6 R Disregard the letters A,E,I,O,U,W,Y, and H.

THE SOUNDEX CODING SYSTEM Every Soundex code consists of a letter and three numbers, such as S-650. The letter is always the first letter of the surname, whether it is a vowel or a consonant. Disregard the remaining vowels and W, Y, and H and assign numbers to the next three consonants of the surname according to the Soundex coding guide. If there are not three consonants following the initial letter, use zerox to fill out the three-digit code. Most surnames can be coded using the Soundex coding guide. Names with prefixes, double letters, or letters side by side that have the same number of the Soundex coding system are described below. NAMES WITH PREFIXES If the surname has a prefix, such as van, Von, De, Di, or Le, code it both with and without the prefix because it might be listed under either code. The surname vanDevanter, for example, could be V-531 or D-153. Mc and Mac are not considered prefixes.

NAMES WITH DOUBLE LETTERS If the surname has any double letters, they should be treated as one letter. Thus, in the surname Lloyd, the second L should be crossed out, in the surname Gutierrez, the second R should be crossed out. . . NAMES WITH LETTERS SIDE BY SIDE THAT HAVE THE SAME NUMBER ON THE SOUNDEX CODING GUIDE A surname may have different letters that are side by side and have the same number on the Soundex coding guide; for example, PF in Pfister (1 is the number for both P and F); CKS in Jackson (2 is the number for C,K, and S). These letters should be treated as one letter. Thus in the name Pfister, F should be crossed out; in the name Jackson, K and S should be crossed out"--Introd.

Some 1920 census soundex films may begin or end with a group of mixed codes. The range of soundex numbers represent the full possible range of mixed codes in the beginning or ending group. Any code in the group may or may not be represented.
