The American Community Survey counts 406 housing units in the whole of Dorris and prints a margin of 81 on that total. Spread over ten build periods, three of them come back holding nearly the same amount of it — 83 units dated to 1939 or earlier, 77 to the 1940s, 78 to the 1990s. Set the oldest row against the 1990s and 83 against 78 is a gap of 5 units, give or take 52, and no two of the three come apart at all.

One comparison the table does settle is the two oldest rows added together — 160 units standing before 1950 against 78 from the 1990s, 82 apart, with a margin of 67 on that difference. The lead is real and it is also an accident of bookkeeping. The table cuts a row at 1949, so the oldest building in town is reported on two lines while the 1990s has a line to itself. Halfway through the stock is 1963, and 11 years of margin are printed on that year, which puts the midpoint inside a stretch the table will not sort at all — 29 units in the 1950s, 46 in the 1960s, 27 in the 1970s and 25 in the 1980s, where even the two furthest apart, 46 and 25, are 21 apart, give or take 34.

None of it decides what a repair here needs. Nothing in this record is finer grained than a ten-year row with a sampling margin under it, and nothing that coarse names a spring, a cable, a drum or a run of track — those get sized off whatever a technician finds hanging there, and sized the same way in a garage finished before 1950 as in one from the 1990s. So a build year is something we write down on a Dorris job rather than something we turn up having assumed.
