Darkness ratings are estimates from satellite data unless marked measured (how we rate darkness). Moonless nights are computed for each place's coordinates; weather isn't included (how). A town has at least 250 people and a grocery store on the map; distances are straight lines, so the drive is longer (how). Map data © OpenStreetMap contributors, ODbL.
