Childhood Lead Poisoning is the most common pediatric public health problem, yet it is entirely preventable. Once a child has been poisoned,
the impairment it may cause is irreversible. Lead harms children's nervous systems and is associated with reduced IQ, behavioral problems, and learning disabilities,
among other health outcomes. While lead paint in homes built before 1978 continues to be the most common source of lead exposure, there are other sources of lead that
can poison a child or adult. No amount of lead is safe for the body.
People may be exposed to lead by breathing or swallowing lead or lead dust. Once it enters the body, lead can become a health hazard.
Lead poisoning can cause learning disabilities, behavioral problems, and, at very high levels, seizures, coma, and even death.
Because lead poisoning often occurs with no obvious symptoms, it frequently goes unrecognized.

The Nationally Consistent Data Measures (NCDMs) for Childhood Lead Poisoning are:
Annual Blood Lead Levels
- Number of Children Tested
- Number of children tested with confirmed blood lead levels between 5 and less than 10 µg/dL
- Number of children tested with confirmed blood lead levels of 10 µg/dL or greater
- Percent of children tested
- Percent of children tested with confirmed blood lead levels between 5 and less than 10 µg/dL
- Percent of children tested with confirmed blood lead levels of 10 µg/dL or greater
Each of the Childhood Lead Poisoning NCDMs are available using the charts on this page.
- Select the measure using the Measure dropdown.
- Choose the grouping by selecting an option from the X-Axis dropdown.
Filter the results by any of the available demographic options by checking the option in the corresponding dropdown.
If no option is selected the total for that demographic will be used when calculating the results.
