Education Report for Southern Arizona Cities, Towns, and Census-Designated Places

Educational attainment rates varied substantially across Southern Arizona in 2022. Hereafter, when discussing multiple cities, towns, or census-designated places (CDP) the general term communities will be used. This article explores 41 of the largest communities within Cochise, Pima, Pinal, Greenlee, Graham, Santa Cruz, and Yuma counties. Due to the importance of mining in Greenlee County, we also include three nearby communities in New Mexico.

In 2022, the Catalina Foothills CDP posted the highest percentage of residents aged 25 and older with a bachelor’s degree or better at 70.4%. This was more than double the state’s rate of 31.8% and the U.S. rate of 34.3%. The cities of South Tucson and San Luis shared the lowest rate at 8.8%. Figure 1 shows the percentage of those aged 25 and older with a bachelor’s degree or better for the Southern Arizona communities.

Educational attainment is a critical component of a region’s potential growth in population, jobs, and long-run income. Regions with a higher concentration of highly educated residents tend to perform better across many socioeconomic indicators such as poverty, unemployment, productivity, and crime rates. Additionally, less educated residents also tend to earn higher wages in regions with a larger concentration of college graduates.

In 2022, the city of Willcox and the town of Duncan had a relatively high share of residents who reported a high school degree as their highest educational level at 39.1% compared to other Southern Arizona communities and the state of Arizona (23.6%). The Catalina Foothills CDP had the highest share of residents with a bachelor’s degree or better at 70.4%. When this is broken down into those with just a bachelor’s degree (31.3%) and those with a graduate or professional degree (39.1%), Catalina Foothills ranked first in both. Several other communities in Southern Arizona had a large share of residents with a bachelor’s degree, including the towns of Oro Valley (30.8%), and Marana (29.0%), and the Vail CDP (27.9%). Figure 2 shows the shares of educational attainment by level for each of the Southern Arizona communities.

Substantial variation exists when comparing those with a bachelor’s degree or higher by age. Predominantly, the 25 to 34-year-old age group had low college attainment levels when compared to both the U.S. and amongst the other age groups. For instance, the city of Willcox posted only 3.8% in this category, while the U.S. rate was 38.1% and the state’s rate was 31.1%. Of the 41 communities, 20 posted lower college attainment rates than the state in the 25- to 34-year-old age group. The Catalina Foothills CDP had the highest college attainment rates among different age groups. For 25–34-year-olds, the rate was 63.6%, for 45–64-year-olds it was 73.1%, and for those 65 years and older, it was 69.4%. On the other hand, the Morenci CDP had the highest college attainment rate of 76.3% for those aged 35–44. Data for each of the Southern Arizona communities are available in Figure 3.

Regions with a higher concentration of highly educated residents tend to have lower poverty rates. When exploring the poverty rate by educational attainment, we find that those with a bachelor’s degree or higher are significantly less likely to live in poverty. For example, in the Ajo CDP, the poverty rate for those with less than a high school degree was 42.7%, compared to 26.5% for those with a high school degree, 12.3% for those with some college, and 8.1% for those with a bachelor’s degree or better. This trend holds for communities such as the cities of Tucson and Bisbee, as well as for most other Southern Arizona communities. The poverty rate by educational attainment in Green Valley is unique, and on average lower, compared to many of the other communities in Southern Arizona, due to the high percentage of retirees in this CDP and therefore of individuals with a fixed retirement income. Figure 4 highlights the poverty rate by educational attainment for each of the 41 Southern Arizona communities.

Educational attainment rates vary significantly by ethnicity across the Southern Arizona communities. The Catalina Foothills CDP had the highest college attainment rates for both Hispanics and White, non-Hispanics, at 62.1% and 72.2%, respectively. Substantial variation exists for many of the Southern Arizona communities between Hispanics and White, non-Hispanics, including communities such as the city of Nogales, which had the largest percentage points difference (35.9). The average difference between Hispanics and White, non-Hispanics for all of the Southern Arizona communities was 11.6 percentage points. This was less than the U.S. difference of 18.9 percentage points. See Figure 5 for the four-year educational attainment rate by race and ethnicity for the Southern Arizona communities.

Educational attainment rates exhibited significant variability by gender across the Southern Arizona communities. The Catalina Foothills CDP had the highest college attainment rates for both males and females at 72.8% and 68.2%, respectively. Substantial variation exists for many of the Southern Arizona communities between males and females, where communities such as the Morenci CDP had educational attainment among females that exceeded that of males by 32.2 percentage points, and in other cases, such as in the town of Clifton, educational attainment in males surpassed that of females by 10.1 percentage points. On average, across the 41 communities, the college attainment rate was 24.5% for males and 27.8% for females.

Educational attainment reflects the share of the population age 25 and older with a given level of education. Respondents report the highest level of education completed. The data come from five-year estimates for 2021 from the U.S. Census Bureau’s American Community Survey (ACS). Note that the ACS five-year estimates are a rolling survey taken over five years therefore, they are only comparable on a five-year interval.
