By Census Bureau figures, the county had roughly 21,756 residents in 2023, spread over about 601 square miles of land. It is a rural county: tight town lots in Hanover, then fields, woods and small acreage splits along the back roads. The Upper Mississippi River National Wildlife and Fish Refuge is part of the Jo Daviess County landscape, and creek or shoreline tracts are common there. Apple River Canyon State Park and Buehler Preserve are a big draw, and the private tracts that border public land are often the first ones hunters and cabin buyers ask about.

Deer hunters scouting the woods between Hanover and Elizabeth use the parcel lines to see how many owners share one ridge or creek bottom.

Acreage and vacant lot search
A vacant-land search near East Dubuque, step by step:
- Turn on the photo basemap and work outward from Galena one road at a time, flagging parcels with no buildings.
- Build a short list of open parcels around Galena with owner names and acreage before you make any calls.
- Check that the tract touches a public road; a landlocked lot near Galena can be hard to finance and build on.

- Rural lots near Blanding may need a septic permit and a well, so ask before you commit.

A survey is the only document that settles where a Jo Daviess County boundary actually runs.
Behind the map: land records in Jo Daviess County
