Childhood lead exposure

Published ZIP-level testing and elevated blood-lead records with documented industrial and housing context.

Read the geography and period first

Testing coverage varies. A ZIP rate describes tested children and should not be read as the prevalence among every child living there.

Western New York

Circles show approximate county centers and are sized by the selected value. They are not patient locations.

Eight-county comparison

Highest reported value to lowest

Placement is descriptive. “Highest” is not automatically “worst,” particularly for access, income, screening, and protective measures.

All New York counties

Sortable-source audit view

62 counties have a reported value for this indicator. Suppressed or unavailable values are not assigned a rank.

Official local detail

The most detailed supported geography

The local map retains the source geography and does not assign county averages to neighborhoods.

Community comparison

Childhood blood-lead surveillance

CDC says surveillance testing is targeted, is not population-based, and cannot be accurately compared between states or counties. WNYAtlas keeps the published local ZIP records visible without manufacturing a benchmark chart.

Selected measure

Childhood blood-lead surveillance

No valid state-to-national comparison. Every row retains its own reporting period.

No responsible benchmark chart is available for this measure.

A comparable Erie–Niagara–New York–United States chart is withheld by design.

Optional environmental context

Open the documentary record without implying causation.

Health statistics and environmental history remain separate by default. These links preserve that distinction while making related records easy to inspect.

Methodology and sources

Every value keeps its source period and geography.

The county comparison is occupational adult lead and is not interchangeable with the childhood ZIP layer; both are labeled separately.
