Step-by-step explanation:
Race Code for Searching Records
In order to search all records, it would be best to use a race code that is inclusive of all races. One such code is '0', which is commonly used to represent 'Unknown' or 'Other'. By using this code, you ensure that no records are excluded based on race.
For example, if the race code '0' is used in an inquiry, it will search for records that include all races, such as records with race codes '1' (White), '2' (Black/African American), '3' (Asian), and so on.
