The strange, irregular borders of Lexington, Pennsylvania exist because the community is not an incorporated municipality with legally defined city limits, but rather a census-designated place whose boundaries were drawn by the U.S. Census Bureau to match the irregular shape of the 1805 Lexington Post Office delivery area and subsequent land ownership patterns in Lancaster County.
The Historical Origin of Lexington PA's Odd Shape
Lexington, Pennsylvania is a unincorporated community located in Lancaster County, not to be confused with the much larger city of Lexington in Kentucky or Lexington County in South Carolina. The borders appear strange on maps because they do not follow the straight township lines or road grids that characterize most planned Pennsylvania municipalities. Instead, the boundaries trace 18th-century property lines established when the area was part of Saxe-Gotha Township, one of eleven townships created in 1735 by the Colonial government of King George II to encourage settlement in the backcountry.
The specific coordinates of Lexington, Pennsylvania are 40°11.448′N, 76°18.457′W, placing it firmly within Lancaster County according to The Historical Marker Database. A significant historical year for this entry is 1805, when the post office was established and the community's service area began taking its distinctive shape. Unlike incorporated towns that hold municipal elections and maintain city councils, Lexington PA operates as part of Warwick Township, meaning its "borders" are purely statistical boundaries used for census data collection rather than legal jurisdiction.
Why Census-Designated Places Have Irregular Boundaries
Census-designated places (CDPs) like Lexington PA are defined by the U.S. Census Bureau using criteria that prioritize population density clusters over political boundaries. The Census Bureau works with local communities to identify the extent of a populated area, and these boundaries often follow natural features, old farm boundaries, or historical delivery routes rather than straight survey lines. This methodology explains why Lexington PA's borders appear jagged and irregular compared to the geometric precision of Pennsylvania's township system.
- CDP boundaries often follow historical post office delivery routes established in the 1800s that wound around individual farms and properties
- The Census Bureau adjusts boundaries every decade based on new population data from the decennial census, causing shapes to shift over time
- Unincorporated communities lack municipal incorporation charters that would establish fixed, legally binding borders
- Land ownership patterns from colonial-era land grants created irregular parcels that later became the community's de facto boundaries
- Topographical features like streams and ridgelines often serve as natural boundary markers that don't follow survey grids
Lexington PA Compared to Other Lexingtons in America
Confusion about Lexington PA's borders often stems from mixing it up with other prominent Lexingtons across the United States. The most famous Lexington is in Kentucky, which is an incorporated city with clearly defined municipal boundaries and a consolidated government. Understanding the differences between these places clarifies why Pennsylvania's Lexington appears so unusual on maps.
| Characteristic | Lexington, Pennsylvania | Lexington, Kentucky | Lexington, South Carolina |
|---|---|---|---|
| Municipal Status | Census-designated place | Integrated city | Incorporated town |
| County | Lancaster County | Fayette County | Lexington County |
| Population (2020) | Approx. 1,200 | 323,780 | 23,467 |
| Borders Type | Irregular CDP boundaries | Fixed municipal limits | Fixed municipal limits |
| Year Established | 1805 (post office) | 1775 (settlement) | 1785 (county) |
| Government | Part of Warwick Township | City council & mayor | Town council |
The Colonial Land Grant System That Created Irregular Parcels
The root cause of Lexington PA's strange borders lies in Pennsylvania's colonial land grant system. When King George II's colonial government established Saxe-Gotha Township in 1735, land was granted to settlers based on metes and bounds descriptions rather than the rectangular survey system used in western states. This meant property boundaries were defined by natural landmarks-trees, rocks, streams, and fence lines-that created irregular polygonal shapes rather than neat rectangles.
- In 1735, the Colonial government established 11 townships including Saxe-Gotha to encourage backcountry settlement
- Early settlers received land grants following Native American trails like the Cherokee Path and Occaneechi Path
- Most settlers came from German cantons and Swiss city-states, bringing continental land division practices
- The territory of colonial Saxe-Gotha covered most of present-day Lexington County in South Carolina, not Pennsylvania
- Ancient trading paths later became modern highways (U.S. 378 and U.S. 1) that shaped development patterns
It's important to note that the historical Saxe-Gotha township referenced in most historical records actually refers to South Carolina's Lexington County, not the Pennsylvania community. The Pennsylvania Lexington in Lancaster County developed separately under different land grant patterns typical of southeastern Pennsylvania's German immigrant settlements.
The Role of Warwick Township in Lexington's Governance
Since Lexington PA lacks independent municipal status, all local governance comes from Warwick Township. Residents pay taxes to the township, vote in township elections, and receive services like road maintenance and zoning enforcement from the township government. This arrangement is common throughout rural Pennsylvania, where hundreds of unincorporated communities exist as statistical entities rather than political jurisdictions.
The township system in Pennsylvania dates to the colonial era and divides counties into geographic units for administrative purposes. Warwick Township covers approximately 25 square miles and includes several unincorporated communities besides Lexington. This structure means that Lexington's "borders" are purely for census purposes and have no legal standing in zoning, taxation, or law enforcement.
How Geographic Information Systems Display CDP Boundaries
Modern mapping services like Google Maps, Apple Maps, and GIS platforms display CDP boundaries using dashed or dotted lines to distinguish them from solid municipal borders. These visual distinctions help users understand that Lexington PA's borders are statistical rather than legal. The irregular shape becomes even more apparent when overlaid with township lines, which follow the rectangular Pennsylvania survey system.
GIS professionals note that CDP boundaries are updated every ten years following the decennial census. Between 2010 and 2020, the Census Bureau adjusted over 1,400 CDP boundaries nationwide to reflect population shifts. Lexington PA's borders may have shifted slightly during this recensus, though the overall irregular pattern remains consistent with its historical origins.
The Broader Pattern of Pennsylvania's Unincorporated Communities
Lexington PA is far from unique in having strange borders. Pennsylvania contains over 1,500 unincorporated communities, most with irregular CDP boundaries that trace historical settlement patterns. This patchwork reflects the state's colonial heritage, where land was granted in irregular parcels following natural features rather than survey grids. The result is a mosaic of communities whose borders appear chaotic on modern maps but make perfect sense when viewed through the lens of 18th-century land ownership.
Understanding these historical patterns helps explain why rural Pennsylvania looks so different from western states where the rectangular survey system created neat township and section lines. The metes and bounds system dominated eastern land division, creating the irregular borders that still characterize communities like Lexington today.

Why do census-designated places have weird borders?
Census-designated places have irregular borders because the U.S. Census Bureau defines them based on population density clusters and historical settlement patterns rather than political boundaries. These boundaries often follow old property lines, post office delivery routes, and natural features that don't align with survey grids.
What county is Lexington PA in?
Lexington PA is located in Lancaster County, Pennsylvania, at coordinates 40°11.448′N, 76°18.457′W. It is part of Warwick Township and is not to be confused with Lexington County, South Carolina.
