March is Developmental Disabilities Awareness Month. Fairfax County celebrates individuals with developmental disabilities for their participation in social, economic, and civic life and the invaluable contributions they make to our community. 
Developmental disability is a broad term to describe an impairment in physical, learning, language, or behavior. Most developmental disabilities begin before a baby is born, but some can happen after birth because of injury, infection, or other factors. These conditions may impact day-to-day functioning, and usually last throughout a person's lifetime. Developmental disabilities occur among all racial, ethnic, and socioeconomic groups. Learn more.
