Phoenix has long been known as the place where the US army first began to deploy troops.
But a new study published by researchers at the University of Arizona shows that the city’s military presence grew as much as fivefold over the last century.
Phoenix’s growth over the past century, which is often described as a boom, is a combination of a booming economy and an increased military presence.
The study, titled Phoenix: A Warrior Community, found that the US military had roughly 12,000 active-duty personnel at the time Phoenix was established in 1876.
By 1910, that number had nearly doubled to more than 16,000, and by the end of the century, it reached nearly 20,000.
The rise of the US Army was driven by a rise in military spending, but a surge in the number of military recruits and officers, the researchers found.
As the city grew, so did its military, the study found.
The population of the city reached more than 40,000 people in 1950, with more than 1,000 serving in the Army.
By 2050, that figure had risen to more more than 10,000 personnel, and as of the end, the military was still in place in the city.
The researchers, who are affiliated with the University’s Center for Strategic and International Studies, looked at Phoenix’s population from the 1890s to the present, the year before the city was established.
They found that from 1900 to 2010, the city had grown by about 10,500 residents.
“Phoenix has been the dominant city in Arizona for a long time,” said Daniel C. Graziano, a co-author of the study and a professor of history and political science at the university.
According to the report, the first census in the Phoenix area was taken in the early 1800s, but census figures were not kept until the late 19th century.
By 1900, the population had reached more that 40,900 people.
By 2010, it had grown to more that 50,500.
As the population grew, it became more of a force in the state.
By 1910, Arizona had more than 100 military bases, and the state’s population had grown from about 12,700 to more like more than 20,700.
In 2010, about 15 percent of the population of Phoenix was military personnel, according to the study.
During the boom years of the late 20th century, Phoenix became home to military bases that expanded the US’s military footprint and the number and strength of military personnel stationed in the area.
But the city has since seen a rapid decline in population.
When Phoenix’s military base at Fort Bliss opened in 1964, the base saw a population of about 7,600 people.
But by the late 1970s, the number had fallen to about 1,400 people.
Today, the Pentagon says there are fewer than 3,000 military personnel in Phoenix.
Meanwhile, the area is becoming more isolated from other major US cities.
The military base that Fort Bliss now houses is near the city of Albuquerque, which has a population about 10 times that of Phoenix.
The Army base that has been in Fort Bliss for over 60 years is in a different part of the state, but it has no permanent military presence there.
What does the future hold for the city?
One thing that has changed is that Phoenix has experienced a major growth in population over the years, but the military presence has declined.
According to the new study, between 1910 and 2010, population in Phoenix increased by nearly 10,600, while military personnel increased by about 5,600.
One of the reasons for this is that the military has seen a decline in its footprint and its size, and it has been able to expand in other ways, like recruiting new personnel, the report said.
Some experts say that a boom-or-bust economic model has kept Phoenix’s growth and the military’s presence steady over the decades.
For example, the economic boom of the mid-20th century saw the city grow from about 11,500 to over 50,000 residents.
By the end in the 1960s, it was up to more as much 30,000 inhabitants.
A boom in tourism also helped keep the military at bay.
Despite this, the growth in the military and the city are not without controversy.
Former President Bill Clinton has said that the boom in military forces in Phoenix contributed to a rise of violent crime in the downtown area, and that he is planning to reopen the city to civilian use, but not the military.
Graziano says that a lot of people still disagree with Clinton’s position.
There is still a lot that the American public does not know about the Phoenix military base, he said.
