1. Define the geographic question before reading the numbers
Batavia is recorded by the U.S. Census Bureau as a municipality in Illinois. The 2020–2024 ACS five-year population estimate for Batavia city is 27,151, with a margin of error of 346. The city has recorded relationships with DuPage County and Kane County. Those facts describe the place and its population estimate; they do not establish legal demand, search volume, competition, lead volume, case volume or revenue. For a firm serving Batavia, that distinction matters when a dashboard shows city, county or broader geographic data. A city label should not silently stand in for every person or household in the two counties.
Recommended approach
Ask Bosseo to show how geographic labels will be defined in the dashboard. Decide whether your review should separate Batavia from DuPage County, Kane County, Illinois-wide visibility or another service area. Use the population record as geographic context only, then evaluate actual tracked activity and the limits of each location field.
