Fresh.Data current as of Apr 24, 2026
PA 18065 (ZIP 18065) sits in Lehigh County within the Allentown-Bethlehem-Easton metro area. The page draws on 1 federal data feed retrieved Apr 24. Health-survey coverage is limited for this ZIP. No NCES schools are mapped to this ZIP in the current dataset. 10 colleges and universities serve the area, with median in-state tuition of $46,800. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. Social vulnerability is low in this ZIP at the 14th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 17 federal disaster declarations affecting this ZIP since 1965. 25.5% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. New residents arriving here predominantly come from Northampton County, PA (IRS SOI Migration, 2022-2023). Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: fair market rent of $1,360 for a two-bedroom, a low 0.0% poverty rate, and a median home value of $169,300. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

What these numbers say together
PA 18065 (ZIP 18065) sits in Lehigh County within the Allentown-Bethlehem-Easton metro area. The page draws on 1 federal data feed retrieved Apr 24. Health-survey coverage is limited for this ZIP. No NCES schools are mapped to this ZIP in the current dataset. 10 colleges and universities serve the area, with median in-state tuition of $46,800. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. Social vulnerability is low in this ZIP at the 14th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 17 federal disaster declarations affecting this ZIP since 1965. 25.5% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. New residents arriving here predominantly come from Northampton County, PA (IRS SOI Migration, 2022-2023). Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: fair market rent of $1,360 for a two-bedroom, a low 0.0% poverty rate, and a median home value of $169,300. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
Both surfaces skew lighter than national averages. That isn’t a verdict — small-area estimates compress real neighborhood-level texture, and a single ZIP reading can miss a district line or a hospital corridor sitting just outside it. Treat this as a starting point for fieldwork, not a conclusion.
Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
