Use Tecumseh as a service-area decision, not a demand forecast
The Census Bureau records Tecumseh city in Pottawatomie County. Its 2020–2024 ACS 5-year population estimate is 6,332, with a margin of error of 25. Those facts help identify the place and its county relationship; they do not establish how many people search for a lawyer, how many firms compete for a query, or whether a particular practice area is viable. For your firm, the useful question is whether Tecumseh belongs in a clearly defined service footprint and whether you can provide meaningful information for someone seeking help there.
Recommended approach
Start by listing the legal services you actually offer and the communities you are prepared to serve. Then decide whether the appropriate footprint is Tecumseh alone, cities throughout Pottawatomie County, or a broader Oklahoma territory. Do not expand the footprint merely because a population figure appears attractive.
