The American Cancer Society's estimates for leukemia in the United States for 2016 are:

  • About 60,140 new cases of leukemia and about 24,400 deaths from leukemia (all kinds)
  • About 18,960 new cases of chronic lymphocytic leukemia (CLL)
  • About 4,660 deaths from CLL

CLL accounts for about one-quarter of the new cases of leukemia. The average person's lifetime risk of getting CLL is about ½ of 1% (about 1 in 200). The risk is slightly higher in men than in women.

CLL mainly affects older adults. The average age at the time of diagnosis is around 71 years. It is rarely seen in people under age 40, and is extremely rare in children.
