Enter any available information about the industry associated with the longest held occupation (e.g., automotive repair, junior high school, trucking, house construction), up to 100 characters.
If the chart identifies the employer's name but does not describe the industry, enter the employer's name (and city if available). If only an abbreviation is given for the industry or employer (e.g., PERS, USD, or FDIC), record it even if its meaning is not known. However, avoid the use of abbreviations where possible.
If no information is available, enter "NR" (not recorded). Do not leave this field blank.
