A nominal-level variable is a categorical variable where the values do not have any inherent order or ranking. Gender is a classic example of a nominal-level variable as the categories (male and female) do not have any order or ranking. Age, ideology, and family income, however, all have inherent order and ranking (e.g. older versus younger, more conservative versus more liberal, higher versus lower income), and are therefore not nominal-level variables.
