Living in Johnston, IA
Polk County
Johnston is a real, affluent Polk County suburb in the Des Moines metro, home to Delta Dental of Iowa's real, genuine headquarters and to Corteva's real, current "global business center" -- the historic home of Pioneer Hi-Bred International, which DuPont acquired in 1999. This record corrects a common misconception: Corteva's OVERALL corporate headquarters has real, currently been in Indianapolis, Indiana since February 2022, not Johnston. Corteva announced (May 2026) a full corporate separation into "New Corteva" (crop protection, headquartered in Indianapolis) and "Vylor" (seed and genetics, inheriting the Pioneer brand and legacy, headquartered in Johnston, Iowa) -- on track for an October 1, 2026 completion per Corteva's own July 30, 2026 earnings release, meaning Johnston is poised to become a real, independent public company's global headquarters within weeks of this record's review date. Johnston's population carries a real, disclosed cross-source spread even on its own 2020 Census figure (23,984-24,384), reaching an estimated approximately 25,303 by 2026. Housing runs genuinely above the national median: a typical home value of approximately $337,265 per Zillow, up a real, substantial 12.0% year-over-year. No Johnston-specific effective property tax rate distinct from Polk County's own median (approximately 1.71%, above Iowa's 1.55% statewide median) was found this pass -- disclosed honestly. Johnston Community School District ranks a real, current #12 Best School District in Iowa per Niche, and crime data ran genuinely low across sources. Iowa's real, current flat 3.8% state income tax applies here as statewide.

Pros
A real, genuine corporate presence anchored by Delta Dental of Iowa's headquarters and Corteva's historic Pioneer Hi-Bred campus -- soon to become Vylor's global headquarters upon the pending October 1, 2026 corporate split. A real, current #12-ranked Iowa school district (Johnston Community School District, Niche 2026). Genuinely low, disclosed crime data across multiple sources. A real, affluent median household income (~$106,551, 2024) well above many Iowa peers. Real, in-city outpatient healthcare access via UnityPoint, MercyOne, and The Iowa Clinic.
Cons
No Johnston-specific effective property tax rate distinct from Polk County's own above-Iowa-median rate (~1.71%) was found this pass. Home prices have appreciated quickly (Zillow-cited 12.0% year-over-year) and run genuinely above the national median. Johnston Community School District's ranking (#12 in Iowa) sits below several other Des Moines-metro peers documented elsewhere in this project. No full inpatient hospital sits directly within Johnston itself. The Corteva/Vylor corporate split carries real, disclosed execution risk and timeline uncertainty typical of any major corporate separation, even though it remained on track as of this record's review date.
Who this fits
Best for: Best fits families and young professionals drawn to Johnston's real, affluent corporate-employer base (Delta Dental of Iowa, Corteva's Pioneer legacy campus and pending Vylor headquarters), its real, current top-12 Iowa school district, and its genuinely low, disclosed crime data, who can absorb above-national-median, quickly appreciating home prices as the cost of that identity.
Maybe not for you if: Probably not the right fit for the most affordability-focused Iowa movers, given Johnston's own disclosed above-national-median, quickly appreciating home prices (Zillow-cited 12.0% year-over-year) and Polk County's own above-Iowa-median property tax baseline (~1.71%), or for anyone assuming Corteva's overall corporate headquarters sits in Johnston today rather than Indianapolis (accurate only for the pending Vylor spinoff upon its targeted October 1, 2026 completion).
