Incidence of Leukemia by Year and Sex, New Jersey, 1990 to 2021
Indicator Report Data View Options

Why Is This Important?
Leukemia is a broad term for cancers of the blood cells. Although it is often thought of as a children's disease, leukemia is ten times more common in adults than in children, and more than half of all leukemia cases occur in people over the age of 65. The type of leukemia depends on the type of blood cell that becomes cancer and whether it grows quickly or slowly. Acute lymphocytic leukemia (ALL) is the most common type of childhood leukemia and also affects adults, especially those age 65 and older. Acute myeloid leukemia (AML) occurs in both adults and children. Chronic lymphocytic leukemia (CLL) most commonly affects adults over age 55, and rarely occurs in children. Chronic myeloid leukemia (CML) occurs mainly in adults.
Definition
Incidence rate of leukemia by sub-type for a defined population in a specified time interval. Rates are age-adjusted to the 2000 U.S. Standard Population. Rates are per 100,000 population.
Data Notes
- Data have been age-adjusted to the U.S. 2000 standard population.
- Incidence rates (cases per 100,000 population per year) are age-adjusted to the 2000 US standard population (19 age groups: <1, 1-4, 5-9, ..., 80-84, 85+). Rates are for invasive cancer only (except for bladder cancer which is invasive and in situ) or unless otherwise specified. 2020 data are considered preliminary and should not be used in trend analyses; an approximate 10% decrease in the number of cancer cases diagnosed in 2020 and compared to 2019 is partly due to the COVID-19 pandemic. Patients experienced difficulties scheduling medical appointments and cancer screening tests in 2020. Incidence data for 2021 are considered preliminary due to possible reporting delays.
