Method
Live counts reflect active lots whose location places them in San Mateo County (by ZIP, or nearest county when a lot lists only a city); “sold” covers lots that closed with a bid in the past year, aggregated from official platforms (GovDeals, GSA Auctions, PublicSurplus, GovPlanet, PurpleWave and others). A sample of the platforms we index, not the entire government-auction universe. Medians are used because auction prices are heavily right-skewed.
