Surprise is a city in Maricopa County, Arizona, USA. The population was 30,848 at the 2000 census; however, rapid growth has boosted the city's population to 117,517 at the 2010 census, an increase of 281%. As such, it is the second fastest-growing municipality in the greater Phoenix metropolitan area (after Gilbert) and, between 1990 and 2000, it was the sixth fastest-growing place among all cities and towns in Arizona.
The city has a 10,562-square-foot (981.2 m2) Aquatics Center, Maricopa County's northwest regional library, a $5.5 million, 20,000-square-foot (1,900 m2) library, and a 100.3 cost of living index.
The city was founded in 1938 by Flora Mae Statler, who named it Surprise as she "would be surprised if the town ever amounted to much". Surprise officials previously thought the city was founded by Statler's husband, real estate developer and state legislator Homer C. Ludden, but in 2010 property records were discovered which listed Statler owning the land before she met Ludden. Although there were only a few houses and a gas station on the one-mile (1.6 km)-square parcel of land when it was subdivided to build inexpensive houses for agricultural workers, Surprise has experienced tremendous growth in the years since. It incorporated into a city in 1960.
Tens of thousands of retirees moved to the city in the 1990s and early 2000s to live in Sun City Grand, an age-restricted resort-like community, with homes built by the property development firm Del Webb. Surprise is about five miles (8 km) northwest of Del Webb's original Sun City development and adjacent to Sun City West.
Sun City Grand has become a large contributor to the city's population, which more than septupled (7 times) from 10,187 to about 75,000 in 2004. Rapid growth has led city officials to estimate the population at over 103,000 as of 2007, a figure the city maintains in spite of more conservative population estimates by the Census Bureau. Thirty-two of the state's top 50 homebuilders cater to new homebuyers, who are attracted by the city's modestly priced homes, its relative proximity to Phoenix, and by the property taxes, which the city claims are among the lowest in the state.
According to the United States Census Bureau, the city has a total area of 69.5 square miles (180.0 km²), of which, 69.46 square miles (179.9 km²) of it is land and 0.04 square miles (0.1 km²) of it (0.03%) is water.
As of the census of 2000, there were 30,848 people, 12,484 households, and 9,725 families residing in the city. The population density was 443.9 people per square mile (171.4/km²).

In recent years, the racial makeup has varied due to the rapid growth of the city.

Largest regional shopping center 
In February 2007, the Surprise City Council unanimously approved an infrastructure reimbursement agreement with Westcor, facilitating construction of the largest regional mall in Arizona, Prasada. The agreement calls for Westcor to bear the cost of construction and installation of up to $240 million in infrastructure at the Prasada site, along SR303 in Surprise. The city will assume ownership of the infrastructure and reimburse Westcor for the cost by rebating sales taxes generated by Prasada itself. At full build out, the city expects to realize $60 million per year in sales taxes and projects that Prasada will create more than 20,000 jobs for local residents.
