CVID does not show a predilection for any specific race.

CVID equally affects males and females.

CVID can occur in infants, young children, adolescents, or even those aged 20-40 years or older. CVID can become evident at any time from infancy to after the fourth decade of life. Peaks of onset occur in children aged 1-5 years and in persons aged 16-20 years. More than two thirds of patients are aged 21 years or older when CVID is diagnosed.
