The growth of Metro Phoenix has averaged over 40% per decade between 1950 and 2000 but its growth slowed to 20% between 2000 and 2010 due to water restraints and other resources. It's predicted that the Metro Phoenix area will reach 6-7 million within 20 years, up from 4.6 million in 2019. Peoria is certain to enjoy some of this growth.
The history of Peoria as a city dates back to 1886. William John Murphy, who worked on the major Arizona Canal project, recruited settlers to create a community in Arizona. Many of the first settlers were from Peoria, Illinois. After a year, a new road called Grand Avenue was laid out to connect the new town sites of Peoria, Glendale, and Alhambra and it became the primary route from Phoenix to Vulture Mine, a gold mine and major settlement in Maricopa County. The town was incorporated as Peoria in 1887.
Within 10 years, a spur line of the Santa, Prescott, and Phoenix Railroad was installed to connect Peoria to Phoenix as well as Hesperia, Alhambra, Glendale, and Marinette. This helped the new town grow steadily. Eventually, the Luke Air Force Base and a growing economy -- as well as mass-produced air conditioning -- allowed Peoria to grow faster than ever. Peoria became a major suburb of Phoenix after WWII thaks to a construction boom.
