Demographics: Marfa, situated on a high plateau of the Chihuahuan Desert between three mountain ranges, can claim an unusual statistic - the town’s population equals roughly half its altitude.  Approximately 2,100 residents live approximately 4,800 feet above sea level.  Of course, this relationship is subject to change based on births, deaths, immigration, and seismic events.  But what’s far more important is Marfa’s success in balancing growth with the preservation of its pristine landscape.
