Incidence of Childhood Acute Lymphocytic Leukemia (ALL) by Year and Age Group, New Jersey, 1990 to 2021
Indicator Report Data View Options
Why Is This Important?
In general, childhood cancers are rare and represent about 1% of all cancers. Leukemias are the most common childhood cancers, accounting for about 30 percent of all cancers in children 0-14 years of age. Acute lymphocytic leukemia (ALL) accounts for about 75 percent of childhood leukemias. At this time, we do not know what causes most leukemias.
Definition
Incidence rate of leukemia in children 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.
97 to 99% of childhood lymphoid leukemias are acute lymphocytic leukemia (ALL).

How the Measure is Calculated
Numerator:
Number of new cases of leukemia in children among a defined population in a specified time interval. Cases were selected using ICCC recode ICD-0-3/WHO recode.Denominator:
Defined population in a specified time interval. Population age groups 0-14 and 0-19 are both found to be useful by the International Classification of Childhood Cancers (ICCC).
