Public Health Atlas · Maternal and infant health

Birth outcomes

County and available ZIP-level measures for prematurity, birthweight, infant mortality, and prenatal care.

Read the geography and period first

Small ZIP populations can change sharply with only a few births. ZIP values describe maternal residence at birth, not a causal exposure location.

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.

Historical trend

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

Premature births before 37 weeks

Erie, Niagara, and New York use 2021–2023 vital-record totals. The national reference is CDC's final 2023 rate; the definition is the same and the period difference is visible.
