escambiaFL = Interpreter["USCounty"]["Escambia county"]


Answer: Escambia County, Florida, United States.

Next; evaluate:

AdministrativeDivisionData[escambiaFL, "BorderingCounties"]


Baldwin County, Alabama, United States;

Escambia County, Alabama, United States;

Santa Rosa County, Florida, United States.

How can I isolate the bordering counties to Escambia County located in Florida; namely, Santa Rosa County? Unfortunately; "County" is not a known type for "Interpreter", so that I cannot use it in conjunction with "Restricted" to select bordering counties within a state. Thank you!

• I simply didn't know (until very recently) that the checkmark must be pressed to accept a solution. Notice that for each of those 37 questions, I have always acknowledged and expressed my gratitude to all those helping me. Thank you @Carl Lange for bringing this issue to my attention. I will press the "just do it" checkmark with a lot of gratitude from now on. (:-) Aug 16, 2019 at 17:15

You can simply use Select for this:

Select[AdministrativeDivisionData[escambiaFL,
"BorderingCounties"], #["ParentRegion"] ==

{Entity["AdministrativeDivision", {"SantaRosaCounty", "Florida", "UnitedStates"}]}
