Hi there!
According to the website leukemia-lymphoma.org the incidence is something like:
"Incidence by Age Group
Incidence rates by age differ for each of the leukemias. The leukemias represented 27 percent of all cancers occurring among children younger than 20 years from 2000-2004. In the 17 SEER areas of the United States, there were 4,799 children under the age of 20 diagnosed with leukemia from 2001-2004, including 3,619 with ALL. It is estimated that in 2007, 3,800 children will be diagnosed with leukemia throughout the United States. About 2,790 new cases of childhood ALL are expected to occur in 2007."
You can find more information from their website:
