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 Phoenix–Mesa–Chandler, 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; such suburban development is likely to continue for the foreseeable future.
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.[3] Pinal County was the second-fastest-growing county in the U.S. between 2000 and 2010.[4]
In 2010, CNN Money named Pinal County as the second fastest growing county in the USA.[5]
Pinal County has been identified as the second riskiest county for combined impacts of climate change from 2040 to 2060, largely due to high risks of extreme heat, fire hazard and economic and crop damages.[6]
According to the United States Census Bureau, the county has a total area of 5,374 square miles (13,920 km2), of which 5,366 square miles (13,900 km2) is land and 8.6 square miles (22 km2) (0.2%) is water.[7]

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 M. 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 now becoming more progressive as is the trend of most largely populated city centers in America. Pinal voters currently still trend more conservative for now. Donald Trump carried the county by the second-largest margin for a Republican since statehood.

Salaries for county elected officials are set by the Arizona Revised Statutes. All county elected officials except the Sheriff (Mark Lamb as of 2017) 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.[20] 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.
