'''Pinal County''' ({{IPAc-en|p|ɪ|ˈ|n|æ|l}} {{respell|pih|NAL}}) is a county in the central part of the U.S. state of Arizona. According to the 2020 census, the population of the county was 425,264,<ref name="QF">{{cite web|title=State & County QuickFacts |url=https://www.census.gov/quickfacts/fact/table/pinalcountyarizona/PST045221 |publisher=United States Census Bureau |access-date=September 27, 2022}}</ref> making it Arizona's third-most populous county. The county seat is Florence. The county was established in 1875.

Pinal County contains parts of the Tohono Oʼodham Nation, the Gila River Indian Community and the San Carlos Apache Indian Reservation, as well as all of the Ak-Chin Indian Community.

Pinal County is included in the PhoenixMesaChandler, Arizona Metropolitan Statistical Area. Suburban growth southward from greater Phoenix has begun to spread into the county's northern parts; similarly, growth northward from Tucson is spreading into the county's southern portions. Pinal County has five cities: Maricopa, Casa Grande, Apache Junction, Eloy, and Coolidge. There are also many unincorporated areas, which have shown accelerated growth patterns in recent years.

The Pinal County Sheriff's Office runs a weekly mini series called Fridays with Frank on YouTube and Facebook which features Deputy Sheriff Frank Sloup conducting traffic stops in an entertaining and educational manner.

==History== Pinal County was carved out of neighboring Maricopa County and Pima County on February 1, 1875, during the Eighth Legislature. In the August 18, 1899, issue of ''The Arizona Magazine,'' the name "Pinal" is said to come from the pine-clad Pinal Mountains.<ref>{{cite book |last=Granger |first=Byrd Howell |date=1983 |title=Arizona's Names (X Marks the Place) |location=Tucson, AZ |publisher=The Falconer Publishing Company |page=483 |isbn=0918080185}}</ref> Pinal County was the second-fastest-growing county in the U.S. between 2000 and 2010.<ref>{{cite web|url=https://www.census.gov/prod/cen2010/briefs/c2010br-01.pdf |archive-url=https://ghostarchive.org/archive/20221009/https://www.census.gov/prod/cen2010/briefs/c2010br-01.pdf |archive-date=October 9, 2022 |url-status=live|title=PopulationDistributionandChange:2000to2010|date=March 2011|publisher=UnitedStatesCensusBureau|page=9|access-date=March 26, 2011}}</ref>

===Population Growth=== Pinal County, Arizona ranks fifth among U.S. counties in percent population growth from July 1, 2023, to July 1, 2024.<sup>[</sup><sup>20]</sup> The county’s estimated population increased from 486,395 in 2023 to 513,862 in 2024, representing a 5.6% growth rate, far above the national average.<sup>[</sup><sup>20]</sup> To understand what is driving this rapid expansion, it is necessary to decompose overall population change into its two main components: natural increase (births minus deaths) and net migration (domestic plus international).

====Natural Increase (births and deaths)==== A key consideration in evaluating natural increase is the county’s mortality pattern over time. In 2019, Pinal County recorded a crude death rate of 732.4 deaths per 100,000 residents, representing a typical pre-pandemic baseline.<sup>[</sup><sup>19]</sup> Mortality then rose sharply during 2020 and 2021, reaching 1,124.0 deaths per 100,000 residents at the height of the COVID-19 pandemic.<sup>[</sup><sup>19]</sup> By 2022, mortality had begun to decline, though it remained elevated relative to 2019 levels.<sup>[</sup><sup>19]</sup> It is expected that as more data becomes available, the downward trend in mortality will continue and gradually return to levels similar to those observed before the pandemic.

Birth patterns show a more gradual change. Pinal County’s birth rate increased from 9.9 per 1,000 population in 2019 to 11.3 per 1,000 population in 2022.<sup>[</sup><sup>19]</sup> Although this represents modest growth, the overall number of births only slightly outpaced the number of deaths during this period. Data from the U.S. Census Bureau’s population estimates confirm this: between April 1, 2020, and July 1, 2024, natural change contributed only 2,011 people to the county’s population growth.<sup>[</sup><sup>21]</sup> This demonstrates that natural increase played a relatively minor role, as 2,011 people make up only a small fraction of the county’s total population increase of 87,855 during this period.<sup>[</sup><sup>21]</sup>

====Migration==== In contrast, migration overwhelmingly drove Pinal County’s expansion. Between April 1, 2020, and July 1, 2024, the county experienced a net migration inflow of 86,082 people.<sup>[</sup><sup>21]</sup> Domestic migration accounted for the vast majority of this increase, with 78,400 domestic in-migrants compared to 7,682 international migrants.<sup>[</sup><sup>21]</sup> Net international migration includes the movement of both U.S.-born and foreign-born persons, movement between the United States and Puerto Rico, and the movement of Armed Forces personnel, however, it still represents only a small portion of total in-migration.<sup>[</sup><sup>21]</sup> The data make clear that domestic migration, not natural increase and not international immigration, is the dominant force behind Pinal County’s rapid growth.

====Age Structure==== The county’s age structure provides further insight into these patterns and reinforces the interpretation that migration is the primary driver of population change. According to ACS estimates, 57.2% of Pinal County’s population in 2023 fell within the working-age range of 18–64, an increase from 56.9% in 2020.<sup>[22]</sup> Although the percentage change is small, the stability and slight rise of the working-age share is notable, especially in a high-growth area. Fast-growing counties often attract working-age adults and families who relocate from larger metropolitan regions, particularly those with higher housing costs or greater congestion. Pinal County’s age distribution aligns with this typical domestic in-migrant profile.

In addition, the data suggest that the county’s recent growth is not primarily driven by retirees or older adults, who would be reflected in a rising population of residents aged 65 and older. Instead, the presence of a slightly increasing working-age majority indicates that population change is shaped not only by the volume of net migration, but also by the demographic characteristics of those migrants. New arrivals to the county appear to be disproportionately young adults, middle-aged workers, and families.

This working-age dominance has several important implications for Pinal County’s development. A growing labor force can support employment expansion and economic productivity. The influx of families may increase demand for school enrollment, childcare services, and related infrastructure. Higher levels of domestic in-migration can also stimulate the housing market, contributing to rising demand and new residential construction. Over the long term, the county’s age structure will also shape future natural increase through population momentum, as a stable or growing share of adults in their childbearing years may help sustain birth levels even as mortality trends return to pre-pandemic patterns.

==Politics== During the 20th century, Pinal was very much a bellwether county in U.S. presidential elections, having supported the winning candidate in every election between Arizona's statehood in 1912 and 2004 except for that of 1968, when Hubert Humphrey won the county by 3.2 percentage points but lost to Richard Nixon. As a result of the urban sprawl from Phoenix spreading into the county, a major political reversal has taken place between it and neighboring Maricopa County since the turn of the millennium. Maricopa County is becoming more progressive while Pinal has trended conservative. In 2024, Donald Trump carried the county by the largest margin since Nixon in 1972, and with the highest vote share for a Republican since statehood. {{PresHead|place=Pinal County, Arizona|source=<ref>{{Cite web|url=http://uselectionatlas.org/RESULTS/|title=Dave Leip's Atlas of U.S. Presidential Elections|last=Leip|first=David|website=uselectionatlas.org|access-date=June 12, 2018}}</ref><ref>{{cite web|url=https://www.ourcampaigns.com/ContainerHistory.html?ContainerID=199|title=Our Campaigns|access-date=June 22, 2025}}</ref><ref>{{Cite news|url=http://apps.azsos.gov/election/2020/2020_general_state_canvass.pdf |archive-url=https://web.archive.org/web/20251214224957/https://apps.azsos.gov/election/2020/2020_general_state_canvass.pdf |archive-date=December 14, 2025 |url-status=live|title=Official Canvass of Results|last=Hobbs|first=Katie|author-link=Katie Hobbs|date=November 24, 2020|work=Secretary of State of Arizona|access-date=April 28, 2026}}</ref><ref>{{Cite news|url=http://apps.azsos.gov/election/2024/ge/canvass/20241105_GeneralCanvass_Signed.pdf |archive-url=https://web.archive.org/web/20251231153438/http://apps.azsos.gov/election/2024/ge/canvass/20241105_GeneralCanvass_Signed.pdf |archive-date=December 31, 2025 |url-status=live|title=2024 General Election Signed Canvass|last=Fontes|first=Adrian|author-link=Adrian Fontes|date=November 22, 2024|work=Secretary of State of Arizona|access-date=March 2, 2026}}</ref>}} <!-- PresRow should be {{PresRow|Year|Winning party|GOP vote #|Dem vote #|3rd party vote #|State}} --> {{PresRow|1912|Democratic|80|352|373|Arizona}} {{PresRow|1916|Democratic|855|1,232|92|Arizona}} {{PresRow|1920|Republican|1,493|1,264|0|Arizona}} {{PresRow|1924|Republican|1,075|988|568|Arizona}} {{PresRow|1928|Republican|1,631|1,419|4|Arizona}} {{PresRow|1932|Democratic|1,000|3,137|47|Arizona}} {{PresRow|1936|Democratic|1,216|3,498|154|Arizona}} {{PresRow|1940|Democratic|1,996|4,411|22|Arizona}} {{PresRow|1944|Democratic|1,909|3,026|22|Arizona}} {{PresRow|1948|Democratic|2,232|3,572|83|Arizona}} {{PresRow|1952|Republican|4,985|4,522|0|Arizona}} {{PresRow|1956|Republican|5,762|5,063|17|Arizona}} {{PresRow|1960|Democratic|6,441|7,232|11|Arizona}} {{PresRow|1964|Democratic|6,956|9,911|5|Arizona}} {{PresRow|1968|Democratic|6,883|7,409|1,954|Arizona}} {{PresRow|1972|Republican|10,584|6,404|571|Arizona}} {{PresRow|1976|Democratic|9,354|10,595|655|Arizona}} {{PresRow|1980|Republican|12,195|9,207|1,856|Arizona}} {{PresRow|1984|Republican|16,464|11,923|232|Arizona}} {{PresRow|1988|Republican|14,966|13,850|364|Arizona}} {{PresRow|1992|Democratic|11,669|15,468|9,602|Arizona}} {{PresRow|1996|Democratic|13,034|19,579|4,282|Arizona}} {{PresRow|2000|Republican|20,122|19,650|1,518|Arizona}} {{PresRow|2004|Republican|37,006|27,252|364|Arizona}} {{PresRow|2008|Republican|59,421|44,254|1,723|Arizona}} {{PresRow|2012|Republican|62,079|44,306|2,297|Arizona}} {{PresRow|2016|Republican|72,819|47,892|8,835|Arizona}} {{PresRow|2020|Republican|107,077|75,106|2,854|Arizona}} {{PresRow|2024|Republican|126,926|80,656|1,984|Arizona}} {{PresFoot}}

==Government== Salaries for county elected officials are set by the Arizona Revised Statutes. All county elected officials except the Sheriff (Ross Teeple as of 2025<ref>{{Cite web |title=Sheriff {{!}} Pinal County, AZ |url=https://www.pinal.gov/772/Sheriff }}</ref>) and the County Attorney make a salary of $63,800, along with county benefits and compulsory participation in the Arizona State Elected Official Retirement Plan.<ref>{{cite web |url=http://www.azleg.gov/ArizonaRevisedStatutes.asp?Title=11 |title=Arizona Revised Statutes |publisher=Azleg.gov |access-date=August 17, 2012 |archive-date=September 12, 2012 |archive-url=https://web.archive.org/web/20120912050114/http://www.azleg.gov/ArizonaRevisedStatutes.asp?Title=11 |url-status=dead }}</ref> In 2020, the Republican Party won complete control of the Board of Supervisors. In 2022, the Arizona Supreme Court deemed their Road Improvement Tax (passed in 2018) as illegal due to the tax only applied to purchases under $10,000. In 2022, the county's elections department came under intense scrutiny following several mistakes in the primary election. At the time, the Elections Department had only two full-time employees. The Board of Supervisors found themselves being accused of not properly funding the Elections Department.
