Lewis is a town in Essex County, Vermont, United States. The town was named for landholders Nathan, Sevignior, and Timothy Lewis.[1] Although incorporated by the state, the town was never formally organized, since it never gained a sufficiently large permanent population. For most of the 20th century, the town had a total population of zero. It reported a population of 2 at the 2020 census;[2] however it is possible due to the town sharing a census block with nearby towns and gores[3] and the introduction of differential privacy in for the 2020 census, that the actual population remained at 0.[4] Indeed, 100% of the town's land that is not federally protected is owned by a single logging company, Weyerhaeuser. The town's affairs are handled by the Unified Towns & Gores Of Essex County.
