Printable Blank US Map with All Counties
This master vector outline of the United States renders all 3,143 counties and county-equivalents across the 50 states and District of Columbia. Drawn from the US Census Bureau's generalized 2017 cartographic boundary files (1:10M) and projected in Albers Equal Area, it represents the ultimate vector basemap for national choropleth epidemiological modeling, presidential election county returns, and logistics network planning.
About this Blank Map of United States All Counties Map

Geography Notes: United States All Counties Map
Cartographic Data Standards: 3,143 County Equivalents
The United States Census Bureau defines 3,143 primary administrative divisions across the 50 states and D.C.
This total includes 3,007 standard counties, 64 Louisiana parishes, 19 Alaska organized boroughs and 11 census areas, 38 Virginia independent cities, Baltimore City (MD), St. Louis City (MO), Carson City (NV), the District of Columbia, and the 9 planning regions of Connecticut.
Every county boundary is rendered as a clean, closed polygon linked to its unique 5-digit Federal Information Processing Standard (FIPS) code, allowing data analysts to join CSV spreadsheets and render choropleths in GIS tools or web SVG layers.
Extreme County Scale Disparities: Loving County to San Bernardino
The 3,143 counties span staggering extremes of population and land area.
In land area, San Bernardino County, California, is the largest in the contiguous US, covering 20,057 square miles—larger than Switzerland. In contrast, Loving County, Texas, holds just 64 residents, while Los Angeles County, California, houses over 9.8 million people—more than 40 individual US states.
Curated Classroom Activities & Spatial Labs for United States All Counties Map
Pedagogical lesson plans and spatial analysis activities designed specifically for printable vector maps of United States All Counties Map:
National Election County Return Choropleth Project
Objective: Construct a county-level presidential election choropleth visualization.
Materials: Printed US Counties Map, presidential election return dataset, colored markers.
- Select a presidential election year and download county-level vote margins.
- Shade counties by partisan victory margin using a 5-class red-to-blue gradient.
- Analyze the visual contrast between geographic land area and population density.
County Land Area Scale Investigation
Objective: Identify and classify the physical geographic factors contributing to the stark size contrast between Eastern and Western US counties.
Materials: Printed US Counties Blank Map, US terrain reference map, colored pencils.
- Identify and highlight the 100th Meridian running north-south through the Great Plains.
- Compare the average county acreage east of the meridian (humid agricultural settlement) with counties to the west (arid rangelands and public lands).
- Color-code the five largest counties in the continental US (San Bernardino, Coconino, Nye, Elko, Mohave) and discuss how water access and public land ownership shaped county boundaries.
The 5 Synchronized Variants Explained
We generate 5 synchronized variations of United States All Counties Map from the same master vector dataset. Each variant is aligned to identical coordinate geometry:
1. Blank Boundary Outline
The foundational boundary outline of United States All Counties Map. Rendered with a clean exterior stroke and zero fill—the optimal version for in-class labeling exams, custom cartographic overlays, or clean graphic design.
2. With Subdivisions (3142 Counties)
Displays the exterior boundary plus internal administrative borders for all 3142 counties. Each subdivision possesses a unique SVG element ID for direct styling and choropleth shading in vector editors.
3. Labeled with True Centroids
Features authentic typographic labels positioned at each administrative territory's mathematical center of mass. Perfect as a master grading answer key or self-study reference sheet.
4. Adjacent-Contrast Color Fill
Filled using an adjacency-contrast pastel palette so neighboring jurisdictions never blend together. Excellent for tactile visual discrimination and regional geography units.
5. High-Contrast Printer B&W
Optimized specifically for monochrome desktop laser and inkjet printers. Uses pure black vector paths (#000000) and ultra-clean white fills to prevent ink-bleeding and toner smudging.

Frequently Asked Questions About United States All Counties Map Blank Maps
Authoritative answers to common questions regarding printing, licensing, vector customization, and curriculum use:
How many counties are shown on this national map?▼
This map displays all 3,143 counties and county-equivalents recognized by the US Census Bureau across the 50 states and the District of Columbia.
Can my computer open an SVG with 3,143 county polygons?▼
Yes. Our vector geometry is optimized to eliminate redundant microscopic vertices while preserving sharp boundaries, resulting in a clean SVG file that opens smoothly in Adobe Illustrator, Inkscape, Figma, or modern web browsers.
Are FIPS codes embedded in the vector layer?▼
Yes. In the SVG download, each county element carries an ID attribute corresponding to its 5-digit state-county FIPS code, enabling direct automated styling via CSS or JavaScript data-binding in D3.js and Leaflet.
