What drives these prices
- Scarce land. Atherton and the Hamptons villages have little room to build.
- Tech wealth. The Bay Area’s fortunes keep the top spot there.
- Second homes. The Hamptons and Fisher Island are bought as second addresses.
- Small samples. A handful of mega-sales can move the median a lot.
