It really depends on the reasoning for wanting to be remote. Some people just love not having people around, in which case you really want low average weekly population density within say 5-10km (out of easy visibility and hearing). Some people are concerned about civilization collapse or civil war or... something (ie, the prepper type). In that case you can imagine population dispersing away from (and possibly towards) major population centers over a period of months, and you want true isolation.
