The total population for metropolitan Phoenix at the 2020 Census was 4,845,832. It is officially designated by the US Census Bureau as the Phoenix–Mesa–Chandler, AZ Metropolitan Statistical Area. The Phoenix Metropolitan Area comprises Maricopa County (2020 population: 4,420,568) and Pinal County (2020 population: 425,264). This includes the Phoenix Metropolitan Area and the Payson, AZ Micropolitan Statistical Area.Īs of April 1, 2020, the Phoenix-Mesa CSA had a population of 4,899,104 making it the fourteenth largest in the nation by population. Office of Management and Budget (OMB) and by the Census Bureau which consists of the entirety of the counties of Maricopa, Pinal and Gila. The Phoenix-Mesa Combined statistical area (CSA) was designated in September 2018 by U.S. The 2000 Census reported the population of the metropolitan area to be 3,251,876. The population of the Phoenix Metropolitan Area increased by 45.3% from 1990 through 2000, compared to the average United States rate of 13.2%, helping to make Arizona the second fastest growing state in the nation in the 1990s (the fastest was Nevada). This also contributed to the entire state's exceptional growth, as the area is home to just over two-thirds of Arizona's population. Metro Phoenix grew by 652,945 people from April 2010 to April 2020, making it one of the fastest growing metro areas in the country. The gross domestic product of the Phoenix Metropolitan Area was $255 billion in 2018, 16th largest amongst metro areas in the United States.Īs of the 2020 census, the two-county metropolitan area had 4,845,832 residents, making it the 11th largest metropolitan area in the nation by population. It anchors the Arizona Sun Corridor megaregion along with the second most populous metropolitan area in the state, the Tucson metropolitan area. The United States Office of Management and Budget designates the area as the Phoenix-Mesa-Chandler Metropolitan Statistical Area (MSA), defining it as Maricopa and Pinal counties. Allen Foundation.The Phoenix Metropolitan Area – also the Valley of the Sun, the Salt River Valley, or Metro Phoenix (known by most locals simply as “the Valley”) – is the largest metropolitan statistical area in the Southwestern United States, centered on the city of Phoenix, that includes much of the central part of Arizona. Oliver, William and Rosemary Hewlett, Gordon and Betty Moore, the David and Lucile Packard Foundation, and the Paul G. The search was supported by contributions from Bernard M. Project Phoenix was the privately-funded continuation of the NASA Targeted Search SETI program and we gratefully acknowledge the use of NASA equipment on long term loan through 2002. In conclusion, we can set upper limits on the power of narrowband transmitters in the vicinity of nearby stars. While millions of signals were detected, all proved to be from terrestrial technology. Candidate signals, i.e., those not in the database, were checked immediately with a "pseudo-interferometric" observation using a second, distant antenna, or by simple on-off observations if the second antenna was unavailable. A database of terrestrial signals found in the previous week was used to match against detections for each observation. The search looked for narrowband signals that were continuously present, or pulsed regularly, and allowed for frequency drift rates of up to about 1 Hz per second. Phoenix used real time signal detection and immediate verification of possible ETI signals. The search had three major observing campaigns using the Parkes 64 meter, the NRAO 140 Foot, and the Arecibo 305 meter antennas. Project Phoenix was a Search for Extraterrestrial Intelligence (SETI) that observed nearly 800 stars within about 80 parsecs over the available frequencies in the microwave spectrum from 1200 to 3000 MHz with a resolution of 0.7 Hz.
