Clarkston, GA (30021)

Clarkston, GA (ZIP 30021) sits in DeKalb County within the Atlanta-Sandy Springs-Roswell metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Health Insurance comes in above the national average at 19.1%. NCES lists 4 schools serving the area, 4 non-charter. 10 colleges and universities serve the area, with median in-state tuition of $15,036. 43% of returns claim the Earned Income Tax Credit (IRS), a higher share than most ZIPs. Federal QCEW filings show 310,019 covered jobs in this ZIP's primary county — a major regional employment hub. CDC's Social Vulnerability Index places this ZIP in the 88th percentile nationally — a highly vulnerable community profile. The most recent FEMA disaster declaration here was winter storm-related (SEVERE WINTER STORM, 2026). Fast-food restaurants outnumber grocery stores roughly 4-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. IRS migration data (2022-2023) shows a net loss of 7,389 residents (1,951 households) — the ZIP's primary county is shrinking. 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: median household income $50,020, fair market rent of $1,580 for a two-bedroom, and a typical home value of $249,526, down 4.7% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

Social Vulnerability Index

The Social Vulnerability Index uses U.S. Census data to identify communities most at risk during public health emergencies and natural disasters. Higher percentiles indicate greater vulnerability. Tract-level scores are aggregated to this ZCTA via Census 2020 ZCTA→Tract crosswalk, weighted by land-area share. Source: atsdr.cdc.gov. Public domain.

Federal Disaster Declarations

FEMA declares disasters at the county level; counts here include every federally declared disaster touching any county that overlaps this ZIP. Statewide declarations and pre-1964 records without county granularity are excluded. Program flags reflect which FEMA assistance categories were activated (Individual Assistance, Households, Public Assistance, Hazard Mitigation). Source: fema.gov/openfema. Public domain.

Air quality

Based on DeKalb County data (2024).

Source: U.S. Environmental Protection Agency, Air Quality System (epa.gov). Public domain. Only counties with EPA AQS monitoring stations appear here (~30% of US counties); rural ZIPs whose primary county has no monitor will not show this section.

Community health profile

Low birth weight (under 2,500 g) accounts for 10.6% of live births in this county — an early-life health input that downstream outcomes track against.

Based on DeKalb data (2025 CHR release).

Source: County Health Rankings & Roadmaps, University of Wisconsin Population Health Institute (countyhealthrankings.org). Annual release. Underlying source datasets vary by measure (CDC BRFSS, NCHS Vital Statistics, AHA, USDA Food Environment Atlas, and others). Figures are county-level and assigned to every ZIP whose primary county matches.

Food access

Among low-income residents, 8.7% are low-access — those without a supermarket within 1 mile (urban) or 10 miles (rural).

Per-1,000 figures show how many of each store type exist in DeKalb County, GA for every 1,000 residents. Higher grocery and supercenter density usually means easier access to fresh food; higher convenience-store-only density (with low grocery rate) often signals a food swamp.

Source: USDA Economic Research Service, Food Environment Atlas (ers.usda.gov). County-level metrics fanned to ZIP via the primary county in the Census ZCTA-county relationship file. Variable years differ per family (stores ~2020, low-access ~2019).

Who’s moving in and out

Incoming households reported an average AGI of $68,076 versus departing households' $72,353.

Source: U.S. Internal Revenue Service, Statistics of Income, Migration Data (irs.gov). Public domain.
