Notes. N = 3,427. Subjective age difference is defined as the difference between subjective age and chronological age (subjective − chronological), where a negative value represents a younger subjective age and a positive value represents an older subjective age. Subjective age change is defined as the difference between Wave 2 and Wave 1 subjective age.
