Where a door is built up out of sections, there is a hinge line across every joint between them, and that is what gets read first, because it settles the question the rest of the visit hangs on: is this happening in one place, or in all of them. One joint standing open while the others sit shut, one hinge leaf pulled away from the stile it is screwed to, one roller not running with the rest — that keeps the work among the parts a door has several of, on the section they are fixed to. The same thing at every joint sends it instead to the parts there is only one of: the counterbalance, whatever it turns out to be and wherever it is mounted, the opener and whatever couples it to the door, the track taken as a run rather than a piece, and the header and jambs all of it is fastened into. Neither answer comes off a build year. It comes off what gets counted and looked at on the day.

Clayton's census table is that question asked about the town, and here it does answer. 1,393 of the 3,975 housing units counted in the city date from the 1990s and 1,119 from the 1970s, 274 apart against a margin of 254 on that difference — so the 1990s clear the arithmetic the Census Bureau uses to compare two of its own estimates, and clear it by very little. 43.8% of the stock was standing before 1980. The decade between those two crests is the thinnest of the three at 577 units, and the median build year, 1984 with a four-year margin printed on it, falls in that quiet stretch rather than in either of the busy ones.

So the largest single thing that table will say about when Clayton's houses were finished covers around a third of them, and none of it reaches the joints: not how many of them a given door has, not what the hinges along them are screwed into, not whether one spring is carrying that door or a pair. Those get counted in the garage.
