If you’ve lived in Surprise for any length of time, you’ve probably noticed it: golf carts cruising past grocery stores, RV resorts that fill up every winter, and entire neighborhoods built around clubhouses instead of cul-de-sacs. That’s not a coincidence. Surprise has one of the highest concentrations of seniors of any city its size in the country, and the story behind why traces back more than 65 years to a cotton farm, a real estate developer, and an idea nobody had tried before.

The Numbers Behind Surprise’s Senior Population

The data tells a clear story. According to U.S. Census Bureau estimates, Surprise’s senior population (65 and older) runs between 20% and 23% of all residents, compared to roughly 18% nationally. The median age in Surprise sits at 41.4–41.7 years, well above the national median of 38.8. As recently as the 2020 Census, 25.4% of Surprise residents were 65 or older, with nearly 9% of all households being a senior living alone.

To put that in perspective, by 2040, the entire U.S. population is projected to reach about 22% seniors, meaning Surprise has essentially been living in the country’s demographic future for two decades already.

It’s also worth noting that Surprise’s senior population has actually softened slightly over the past few years, even as the raw number of older residents keeps growing. The city’s overall population has surged past 175,000, fueled largely by new family-oriented subdivisions on its western and northern edges. So while younger families are diluting the percentage, the actual count of seniors calling Surprise home continues to climb year after year.

Snowbird Season Adds Another Layer

The numbers above only capture year-round residents. Every winter, Surprise’s population swells further as snowbirds arrive from colder states to spend the season in the area’s RV resorts and seasonal rentals. Surprise’s Sun River retirement communities alone are joined by roughly two dozen nearby RV parks that fill up between November and April, with residents taking advantage of golf-cart-friendly streets, low-speed roads, and a full slate of winter activities. For a few months each year, the city’s effective senior population runs even higher than Census data alone would suggest.

It Started with a Cotton Field and a Bold Idea

The real explanation for Surprise’s senior-heavy population isn’t really about Surprise at all. It’s about what was built right next door.

In 1960, developer Del E. Webb unveiled Sun City on what had been farmland just outside Phoenix, marketing it as the world’s first active-adult resort retirement community. Nobody had built anything quite like it before: a town designed entirely around retirees, with golf courses, recreation centers, and a lifestyle centered on recreation, social engagement, and active living. The concept was such a gamble that even Webb’s own team wasn’t sure it would work.

It worked beyond anyone’s expectations. More than 100,000 people showed up for Sun City’s three-day opening weekend, ten times the number organizers expected, and Del Webb himself landed on the cover of Time magazine two years later. Sun City went on to become the largest and most successful retirement development in the country, fundamentally changing how Americans thought about what retirement could look like. Today, Sun City is home to nearly 40,000 residents, and more than 75% of them are over 65.

Sun City sits directly against Surprise’s boundary, and as Phoenix’s West Valley grew, Surprise inherited the gravitational pull of that retirement legacy.

Sun City West, The Grand, and “Retirement Row”

Del Webb didn’t stop at one community. Sun City West followed in the late 1970s, built 2.5 miles west of the original, and is home to nearly 17,000 homes today. Then came Sun City Grand, now rebranded as The Grand, built directly inside Surprise’s city limits starting in 1996. The Grand spans more than 4,000 acres with close to 9,800 homes, four championship golf courses, multiple recreation centers, and a rule that at least one resident per household must be 55 or older (with a small allowance for buyers as young as 45).

Locals sometimes call the stretch of Bell Road running through this area “Retirement Row,” because it strings together Sun City, Sun City West, The Grand, and several other age-restricted communities almost back-to-back. Arizona now has more than 100 age-restricted retirement communities statewide, with many of them located in or around Surprise.

This is, in plain terms, the single biggest reason Surprise’s senior population runs so far above the national average: an entire planned ecosystem of retirement communities sits inside and around the city, each one purpose-built to attract and keep retirees for decades.

Why Retirees Keep Choosing Surprise

The history explains how this all started, but it doesn’t fully explain why people keep choosing Surprise today, decades later. A few practical reasons stand out:

• Climate – Arizona offers some of the most sunshine in the country, with a dry climate that many retirees find easier on arthritis and respiratory conditions than humid or cold-winter regions.
• Affordability relative to the rest of the Valley – Surprise’s cost of living runs only modestly above the national average, driven primarily by housing costs, while groceries, utilities, and healthcare expenses remain close to or below national averages. That makes it considerably more affordable than nearby Scottsdale, while still offering Phoenix-metro amenities.
• Tax treatment – Arizona doesn’t tax Social Security benefits at the state level, has no estate or inheritance tax, and keeps property taxes among the lowest in the country, all meaningful advantages for retirees living on fixed incomes.
• Built-in lifestyle and entertainment – Surprise Stadium, home to spring training for the Texas Rangers and Kansas City Royals, was voted America’s best spring training facility by USA Today. Add nine golf courses, a dedicated tennis and racquet complex, and dozens of community clubs, and there’s rarely a shortage of things to do.
• Healthcare access built for this population – Communities like The Grand were developed with convenient access to healthcare in mind from the start, with hospitals and specialist offices clustered nearby specifically because the surrounding population skews older.

What This Means for Local Families and Caregivers

A senior population this large changes daily life in ways that go beyond golf carts and clubhouses. It means more families navigating aging-in-place decisions, more demand for skilled caregivers, and more conversations about what kind of support makes sense as a parent or spouse gets older.

One of the most common questions families face is simply where to start. If you’re trying to figure out what level of support your loved one actually needs, our guide on how to find a trusted in-home caregiver will walk you through what to look for, what questions to ask, and how to vet an agency versus an independent caregiver—a process that’s become more important as demand for high-quality caregivers has grown alongside the senior population itself.

Another question families frequently ask is whether a loved one should remain at home with support or move into a senior living community. With Surprise surrounded by both robust home care options and dozens of established 55+ communities, families genuinely have real choices here more than residents of most other U.S. cities ever get. Our breakdown of which option costs more, in-home care or assisted living, can help you think through the financial side of that decision in detail.

Aging in Place: The Quiet Trend Behind the Numbers

It’s worth noting that many of Surprise’s seniors aren’t living in age-restricted communities at all. They’re aging in place in ordinary neighborhoods throughout the city, often in the same home they raised a family in decades ago. National surveys consistently show that a large majority of older adults say they’d prefer to stay in their own home as long as possible rather than relocate, and Surprise’s extensive network of home care providers makes that preference both realistic and safe.

If you’re researching home care options in Surprise for a parent or spouse, you’re in a city that, unlike most of the country, was essentially built with exactly this need in mind. Amada Senior Care offers a free, no-pressure consultation to help your family figure out what kind of support actually fits your situation, whether that’s a few hours a week or full daily care.
