No racial predilection exists for CRPS 1. Sexual distribution is equal. Although CRPS 1 can occur in children, the age of onset in most patients CRPS 1 is 30-60 years, and the mean age is 49 years. [9]

A Scottish study estimated that the incidence of CRPS in children 5-15 years of age is 1.2 per 100,000. Girls constituted 73% of patients. Most cases involed a single site, with legs often affected than arms and the right side more often affected than the left. Clear trauma had occurred at the onset of the illness in most cases. Diagnosis was made a median of 2 months (range, 1-12) after the onset of symptoms. [10]
