Incidence of Childhood Leukemia by Sex and Age Group, New Jersey, 1990-2020

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 age 0 - 14 years. Acute lymphocytic leukemia (ALL) accounts for about 75 percent of childhood leukemias. At this time, we do not know what causes most leukemias.


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

Incidence rates (cases per 100,000 population per year) are age group-specific. Rates are for invasive cancer only (except for bladder cancer which is invasive and in situ) or unless otherwise specified. Number of cases (numerator) is the total count of cases over the defined interval.

Data Sources

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).
