Its population was 152,750 at the 2010 census, up from 116,670 at the 2000 census. Palmdale is the 33rd most populous city in California. In 2013, the Palmdale / Lancaster urban area had an estimated population of 513,547.History"Palmenthal", the first European settlement within the limits of Palmdale, was established as a village on April 20, 1886, by westward Lutheran travelers from the American Midwest, mostly of German and Swiss descent. According to area folklore, the travelers had been told they would know they were close to the ocean when they saw palm trees. Never actually having seen palm trees before, they mistook the local Joshua trees for palms and so named their settlement after them. (Palmenthal is German for Palms Valley.) According to David L. Durham Joshua trees were sometimes called yucca palms at the time, which was the reason for the name. The village was officially established upon the arrival of a post office on June 17, 1888.
