U.S. ZIP Code Areas (Five-Digit) represents five-digit ZIP Code areas used by the U.S. Postal Service to deliver mail more effectively. The first digit of a five-digit ZIP Code divides the United States into 10 large groups of states numbered from 0 in the Northeast to 9 in the far West. Within these areas, each state is divided into an average of 10 smaller geographical areas, identified by the second and third digits. These digits, in conjunction with the first digit, represent a sectional center facility or a mail processing facility area. The fourth and fifth digits identify a post office, station, branch or local delivery area.

This is a historical measure for Strategic Direction 2023. For more data on Austin demographics please visit austintexas.gov/demographics. This measure answers the question of percentage of zip codes that are comprised of 70 percent of more of the composition or race of residents. This indicator calculated the mix by dividing a racial category by total population. Data collected from the U.S. Census Bureau, American Communities Survey (5yr), Race (Table B02001). American Communities Survey (ACS) is a survey with sampled statistics on the citywide level and is subject to a margin of error.

78744 Zip Code Feature Layer This feature layer represents the 78744 zip code boundary within Travis County and is used in this StoryMap to provide geographic context for Austin Public Health (APH) Community Health Worker (CHW) outreach efforts. On June 8, 2024, APH CHW Strike Teams conducted a targeted West Nile Virus (WNV) education campaign in the 78744 zip code, an area with high social vulnerability and environmental factors that may contribute to increased mosquito activity and disease transmission. This outreach aimed to:

Assess community awareness of WNV transmission and prevention strategies Distribute educational materials on mosquito control and personal protection Engage with residents to encourage proactive public health behaviors

Why the 78744 Zip Code? The 78744 zip code was identified as a priority area for WNV education due to:

Social Vulnerability Index (SVI) Considerations – Populations with higher vulnerability may have limited access to health resources or face greater risks from vector-borne diseases. Environmental Risk Factors – Standing water, dense vegetation, and urban drainage patterns that may support higher mosquito populations. Historical Public Health Needs – Previous outreach efforts have highlighted the importance of continued engagement in this area.

Feature Layer Use This feature layer helps visualize the geographic scope of the CHW outreach efforts and supports public health decision-making by aligning intervention strategies with spatial data and community needs. Future applications of this layer may include:

Mapping mosquito surveillance data and environmental risk factors Overlaying additional public health data for targeted outreach Informing response strategies for future vector-borne disease outbreaks

By incorporating geographic data into public health initiatives, Austin Public Health can ensure a more data-driven, equitable, and effective approach to disease prevention and community engagement.

This dataset shows all high schools that were included in the 2020 TEA 4-year graduation rate report, and indicates their street address, zip code, district, and type of school (private/charter).

This map displays the survey area of the Community Assessment for Public Health Emergency Response (CASPER) that was conducted in the Eastern Crescent in the Spring of 2023, and was used in the Resilience CASPER 2023 StoryMap. Below are the descriptions of each layer used: The "Area of Interest" layer is the outline that contains 15 zip codes: 78757, 78752, 78753, 78754, 78723, 78724, 78721, 78742, 78744, 78725, 78719, 78758, 78702, 78741, and 78617. These zip codes were defined, as best possible, to match the census blocks within the ESRI Geographic Information Systems (GIS) Community Health Assessment tool as our boundary for the survey.The "Cluster" layer contains the 30 clusters, with a total of 9,053 housing units, that were randomly selected by the GIS tool for a representative sample of 210 households to interview in our defined census blocks. Clusters with zero households were filtered out to ensure they were not selected. One cluster was selected twice for 29 total clusters.The "Climate Vulnerability" layer is not owned by Austin Public Health. The vulnerability index used is calculated by various factors. These factors include social vulnerabilities like income level, health insurance status, or language barriers and environmental exposures like flooding, wildfire, and urban heat. Areas on the map that are red indicate higher levels of vulnerability and exposure. This data can be found at Austin Area Sustainability Indicators (A2SI).
