The numbers are in, and they confirm what anyone driving Interstate 10 northwest of Tucson has watched happen in real time: Marana is one of the fastest-growing places in Arizona. New population estimates released in May 2026 rank the town fourth statewide for year-over-year growth, after it added more than 3,500 residents in a single year — a 5.7% jump that lifted its population to roughly 66,000. For a town that counted 51,908 people at the 2020 census, that is a fast five-year run. Here is the June 12, 2026 High-Growth Area rundown on where Marana sits, what is driving the climb, and what it means for home prices. ~66,000 — Estimated population, mid-2025. +5.7% — One-year growth — 4th in Arizona. ~13,000 — Residents added since 2020. $414K — Median home sale price, late 2025 Where Marana Is — and Why It Keeps Filling In Marana stretches northwest from Tucson along Interstate 10, sitting mostly in Pima County with a small piece in Pinal County, and it spreads from the Santa Cruz River valley up against the Tortolita Mountains. The simple reason it absorbs so much of the region's growth is land: where Tucson and Oro Valley are largely built out, Marana still has open, developable ground with direct I-10 frontage and interchanges at Twin Peaks, Tangerine, and Marana roads feeding it. That combination — highway access plus room to build — is why national homebuilders keep planting subdivisions here rather than fighting for infill lots closer in. What the New Estimates Actually Say The headline figure comes from population estimates released in May 2026. From mid-2024 to mid-2025, Marana grew an estimated 5.7% and added more than 3,500 residents, enough to rank fourth-fastest among Arizona cities by year-over-year rate. Zoom out to the full post-census window and the picture is just as striking: from 2020 to 2025 the town added close to 13,000 residents, about a 24.5% increase, and was the only Pima County community to land in Arizona's top ten for that stretch. The contrast matters locally — over the same period, growth in Tucson and several of the state's larger cities largely flattened, so the regional gains have been landing disproportionately in suburban towns like Marana. What's Driving the Growth Master-Planned Communities (Gladden Farms, Saguaro Bloom, Dove Mountain): Growth concentrates in planned communities across north and south Marana — Gladden Farms, Saguaro Bloom, and the Dove Mountain area against the Tortolitas — with national builders active and the town projecting more than 1,000 new single-family home permits in the coming fiscal year. Jobs & Retail (Aerospace, Tucson Premium Outlets, I-10 logistics): Employment anchors include aerospace and defense manufacturing and logistics and industrial space along the I-10 corridor, plus the open-air Tucson Premium Outlets — more than 70 brand-name stores at the Twin Peaks interchange off exit 244. Recreation & Resorts (Tortolita trails, The Loop, Dove Mountain golf): Amenities include the Tortolita Mountain Preserve trail network, a stretch of The Loop shared-use path along the Santa Cruz River, and the Forbes five-star Ritz-Carlton, Dove Mountain resort with its Jack Nicklaus Signature Golf course. What It Costs to Buy In For all that growth, Marana's pricing has stayed moderate by Sun Belt standards. The median home sale price was about $414,000 in late 2025, up roughly 3.4% year over year, at around $224 per square foot, with homes selling in about two months. By spring 2026 the median list price sat near $429,900. New construction spans a wide band, from townhomes and entry-level product in the low $300,000s up through larger single-family and semi-custom homes in the Dove Mountain foothills, so the headline median understates how much the range varies by community. None of this is investment advice — it is context for why a buyer comparing northwest-side options often runs the Marana corridor against Oro Valley and Tucson's northwest before deciding. Quick reference (June 12, 2026): Marana runs northwest from Tucson along Interstate 10, mostly in Pima County. Population estimates released in May 2026 put the town near 66,000, up an estimated 5.7% (more than 3,500 residents) from the prior year — fourth-fastest in Arizona — and up close to 13,000 residents (about 24.5%) since the 2020 census count of 51,908. The town projects more than 1,000 new single-family home permits in the coming fiscal year. Median home sale price was about $414,000 in late 2025, with a spring 2026 median list near $429,900.

The Takeaway Marana's run is no longer a forecast — it is showing up in the official counts, and it lands it among the handful of Arizona towns adding people fastest while the state's biggest cities hold flat. For residents already here, that means more rooftops, more retail at the interchanges, and steady road and utility work to keep up. For anyone weighing the northwest side, it is a reminder that the corridor's pricing and inventory are being shaped by how much new construction keeps coming online. Either way, the May 2026 estimates put a number on a trend that has been visible from the I-10 shoulder for years.
