CEN Ethnicity Group4 Line Code

Lists the line code for the fourth recorded ethnicity of an individual if applicable, and is otherwise null. Note: Line code variables are linked to the actual responses in the synonym files. These are applicable for detailed analysis of ethnicity. For example, a person might give Muong and Kachin and Karen as ethnicities, all of which fall under the same census ethnicity classification code (SEA nec) but each would have different line codes. All line codes should be in Aria.
