The limited street infrastructure includes just two roads with carrier service: Tiff Lane and Coverres Lane. With only 38 occupied households total, the community reflects Missouri's pattern of rural settlement where post offices anchor small population clusters. Four residents identify as Black, eight as multiracial, and the rest as white. The median age of 44.3 years sits right at Missouri's state average, suggesting a stable mix of working families and retirees rather than a population skewed young or old.
With only two streets recorded in carrier route data, Tiff's infrastructure reflects its small population. The eponymous Tiff Lane carries most delivery points, while Coverres Lane serves a handful of addresses. These aren't tourist destinations or tribal roads—they're simple rural lanes serving a handful of households in southeast Missouri farmland.
