Labels are meant to provide descriptions of variables. These descriptions are often longer versions of variable names. Variable names can be only eight characters long, which is usually too short for a descriptive and readable name. Labels can be up to 256 characters long. These labels are used in your output to identify the different variables.

Click the Variable View tab on the bottom of the Data Editor window.

In the Label column of the age row, type Respondent's Age.

Type Marital Status as the label for the marital variable.

Type Household Income as the label for the income variable.

Type Gender as the label for the sex variable.
