About these units
Township (township)
A township, as used in the U.S. Public Land Survey System (PLSS), is an area equal to 36 square miles, arranged as a 6-mile × 6-mile square. It is a cornerstone unit of American land division, originating during the late 18th-century settlement of the American frontier. Townships standardized how land was surveyed and sold, allowing the federal government to systematically divide territory for settlement, homesteading, and revenue generation. They were subdivided into 36 sections, each one square mile in area. This grid-based system profoundly shaped American geography. Roads, property lines, agricultural fields, and county boundaries in much of the Midwest and West follow township geometry. Even today, PLSS townships remain legally relevant in land deeds, zoning regulations, and cadastral surveys.
Section (section)
A section is a unit of area equal to one square mile, or 640 acres, derived from the PLSS township system. Each township contains 36 sections arranged in a 6-by-6 grid. Sections were historically granted to settlers, railroads, and states for development, education funding, and agricultural expansion. Because a section is large but manageable, it provided a logical unit for dividing land among homesteaders. Even today, the section persists as a foundation of rural property boundaries. Many farms, ranches, and municipal boundaries reference section lines, reflecting how 19th-century surveying still shapes 21st-century land use.
