Children with Elevated Blood Lead Levels

What does this measure?

The percentage of screened children aged 9 months to 4 years that had confirmed elevated blood lead levels, expressed as a rate per 1,000 children ages 0 to 4.

Why is this important?

Exposure to lead, even small amounts, significantly increases a child's risk of developing long-lasting cognitive, physiological and behavioral problems.

How is our county doing?

Within Essex County, the cities of Lynn and Lawrence had the highest rates in 2017 - at 6.9 and 4.5, respectively - although each was a reduction in rate since 2010.
