Cross Delmar Boulevard and life expectancy drops 15 years, home values fall by a quarter-million dollars, and eviction becomes twice as likely. In St. Louis, a single street decides almost everything.
Every city in this wave has a dividing line — Troost in Kansas City, the tracks in Las Vegas, a highway in Tampa and Columbus. St. Louis has the most extreme one in the country, and it's a single boulevard you can stand on. To the south of Delmar: leafy, affluent, white, long-lived. To the north: disinvested, poorer, Black, and — by the region's own public-health researchers' account — dying as much as 15 years earlier. Everything this wave has documented about how race shapes housing stability is visible here in the span of one crosswalk.
| Directly across Delmar Boulevard | North | South |
|---|---|---|
| Racial majority | 98–99% Black | 73% white |
| Median home value | ~$73,000 | ~$335,000 |
| Median household income | ~$18,000 | ~$50,000 |
| Residents with a bachelor's degree | ~10% | ~70% |
| Life expectancy (63106 vs. Clayton 63105) | 67 years | 85 years |
These aren't neighborhoods separated by miles. They are separated by a street. A home worth $73,000 sits across the pavement from one worth nearly five times as much; a resident with an 18-year shorter life expectancy lives across an intersection from one who will, on average, outlive them by nearly two decades. The zip code 63106, north of Delmar, has an average life expectancy of 67 — lower than many developing nations.
The City of St. Louis publishes an equity dashboard that measures its own racial disparities against a "score of 100" that would represent no gap at all. On eviction, it is nowhere close: the city states outright that eviction is twice as common for renters in majority-Black tracts as in majority-white ones. Those majority-Black tracts are, overwhelmingly, north of Delmar. The eviction map and the segregation map are the same map.
And the pressure is rising, not easing. St. Louis landlords filed nearly 11% more evictions in one recent year than the year before, part of a broader Missouri pattern of fast, cheap filings meeting or surpassing pre-pandemic levels. As in Kansas City, filings here are concentrated among a small number of buildings and landlords who treat the court as a routine collection tool.
Here is the finding that makes St. Louis essential to this wave. A 2025 peer-reviewed study — scraping every eviction case in St. Louis City and County from 2017 through 2024 — examined how eviction rates behaved before, during, and after the federal moratorium. The moratorium worked: it dramatically cut evictions in high-risk communities while it was in place. But the researchers found that in majority-Black neighborhoods, eviction filing rates rebounded aggressively during the moratorium and to an even stronger degree afterward — a sharper snap-back than in majority-white neighborhoods, and one that persisted even though more than $79 million in emergency rental assistance flowed to St. Louis-area renters to cushion the moratorium's end.
Delmar didn't happen by accident, and this wave has now seen every tool that built it. In 1916, St. Louis passed a residential segregation ordinance designed to keep neighborhoods racially homogeneous — one of the earliest such laws in the country. Restrictive covenants (the St. Louis case Shelley v. Kraemer that eventually struck them down at the Supreme Court originated here), redlining, blockbusting, and the mid-century decision to concentrate public housing north of Delmar all hardened the boundary. Urban renewal razed the Black community of Mill Creek Valley in the 1950s. Each policy did its part; the result is a line so sharp the BBC could photograph it.
North of Delmar also holds The Ville — the historic heart of Black St. Louis, home during segregation to a thriving Black middle class, to Sumner High School (the first Black high school west of the Mississippi), and to figures like Chuck Berry, Josephine Baker, and Tina Turner. Like Sunnyside in Houston, King-Lincoln in Columbus, and the Historic Westside in Las Vegas, it was a place of Black achievement built under constraint — and it now sits inside the neighborhoods carrying the region's highest eviction burden.

The Delmar study's finding is, in a sense, PTI's entire thesis stated as research: a one-time cushion at the moment of crisis doesn't change the machine. Perfect Tenant Innovation is built to work on the machine itself — the first of the month, every month — by rewarding on-time payment, building a tenant's credit through rent, and giving landlords a documented reason to accept a payment plan instead of a filing. It's not $79 million delivered at the end; it's a structural change to whether the shortfall becomes a case at all, applied continuously, one household at a time.
The Ville built a thriving Black community on the wrong side of a line drawn to contain it. PTI can't erase the line — but it can help make sure a rough month north of Delmar doesn't end the way the map says it should.
