I'd estimate the Nilles Corner area as having four farmsteads and one abandoned farmstead, for a total of seven houses. Osborne Corner appears to have three farmsteads and five houses. I suspect that much of what you're seeing as "households" are actually farm outbuildings. The best way I've found to identify "real" hamlets is the presence of a cemetery. A group of people who consider themselves a community will usually have their own cemetery, while a group of people who are filing paperwork for personal advantage won't. See Anatone[1] (population 48) or the smaller Lone Pine[2] for examples of a real hamlet. > So, using this area as an example, what would be a more sensible > highway classification for you?

Most of them are mis-tagged as residential; I'd consider them to be unclassified. Some of them, especially the unnamed ones, are probably tracks. Leahy Road/P Road between WA-17 and Nilles Corner, and Y Road between WA-174 and Osborne Corner might be tertiary, since they look like improved collector roads for the farms in the area. There's probably a mis-tagged driveway or two in the area, but I haven't really looked closely.
