Charted: Half of U.S. Renters Spend Over 30% of Income on Rent — Which Metros Are Worst?

The standard affordability rule of thumb — keep housing under 30% of household income — stopped describing the typical U.S. renter years ago. By the 2023 American Community Survey vintage that Harvard’s Joint Center for Housing Studies (JCHS) tabulates in America’s Rental Housing, half of all renter households spent more than that share on rent and utilities. That is 22.6 million households, including 12.1 million that crossed the severe line of 50% of income. The national rate sat near 47% as recently as 2019; the pandemic rent spike erased the modest mid-2010s improvement and left the burdened share 3.2 percentage points higher than the pre-pandemic floor.

The interactive dashboard above is built for the metro question desks actually ask: which markets push the largest share of renters past 30% and 50% of income, and how did those shares move since 2015? Toggle Metro ladder, 2015 → 2023, National path, By income, and Regions & tiers. Filter by Census region and re-rank metros by burden, severe burden, or vintage delta. The rest of this post walks the same perimeter in narrative form — with caveats, a metro table, and the income-band story that national averages hide.

What “cost burden” means in ACS and JCHS

Gross rent in ACS Table B25070 is contract rent plus estimated utilities. JCHS follows the conventional split: moderate burden is 30–50% of household income; severe burden is more than 50%. Households reporting zero or negative income are treated as severely burdened; households that do not pay rent are treated as unburdened. Those conventions matter at the tails — they inflate severe counts in thin-income cells and mute burden rates in employer-provided or zero-rent stock — but they are the published series every housing desk cites.

The national path in the dashboard skips 2020, when ACS collection broke down during the pandemic. From 2015 through 2019, the burdened share eased from roughly 48% toward 47%. Then 2021–2022 snapped the series back to a 50% plateau that held in 2023 even as asking-rent growth cooled. Cooling asking rents did not unwind leases already signed, nor restore the low-rent stock lost to inflation and filtering. JCHS counts 22.4 million burdened households in 2022 and 22.6 million in 2023 — a new household record even while the rate stayed flat at half.

Florida metros sit at the top of the ladder

Among large metros, the 2023 cost-burden ranking is not a coastal California monopoly. JCHS’s affordability update places five Florida markets at the top of the large-metro list: Cape Coral at 65%, Miami at 63%, Orlando and North Port at 59%, and Tampa at 58%. Rapid in-migration, insurance and tax pass-through into rents, and competition from higher-income remote and retiree households all show up as higher shares of local renters past the 30% line. New Orleans (58%) joins them on low incomes rather than peak rents; Riverside (58%), San Diego (57%), and Las Vegas (57%) keep the West near the same ceiling.

Even the “affordable” end of the top-100 list is not comfortable. JCHS notes that the lowest large-metro burden rates still leave about 42% of renters cost-burdened in places like Des Moines, Pittsburgh, and Wichita. Exactly half of the 100 largest metros cleared a 50%+ burden rate in 2023, and 89 of 100 saw burdens rise between 2019 and 2023. The dashboard’s metro panel compresses that landscape into a sortable ladder and a vintage scatter: points above the 2015=2023 diagonal worsened; bubble size tracks renter-household scale so a Miami move outweighs a Cape Coral print in absolute exposure.

Cape Coral’s +13 pp move since 2015 is the panel’s steepest climb; Las Vegas and the Florida I-4 corridor print mid-to-high single-digit gains. Los Angeles and New York look “stable” only because they were already expensive — their 2015 baselines sat near 50–55%, so small deltas still leave more than half of renters burdened. Chicago is one of the few large markets in the panel with a slight improvement versus 2015, and even there nearly half of renters remain above the 30% line.

Severe burdens are the half-of-income cliff

The 30% threshold is the headline. The 50% threshold is the eviction-risk and residual-income cliff. Nationally, 27% of renter households — 12.1 million — were severely cost-burdened in 2023. That is not a small left-tail curiosity; it is more than one in four renter households. In the Florida leaders, severe shares climb into the low-to-mid 30s. Low-income bands dominate the severe count: 67% of renters earning under $30,000 spent more than half their income on housing, and those households still account for roughly three-quarters of all severe cases.

Severe burden is also where race and household structure show up most clearly in JCHS’s national cuts. Black (57%) and Hispanic (53%) renter households have higher overall burden rates than white or Asian renters (45–46%). Single-parent (62%) and single-person (59%) households sit well above married couples without children (33%). Those composition effects do not “explain away” metro rankings — Miami’s renter mix and Cape Coral’s insurance-driven rent spike are different mechanisms — but they do mean a metro with the same median rent can print very different severe shares if its renter income distribution is thinner.

Middle incomes absorbed the sharpest rise

The most under-appreciated shift in the JCHS update is not that poor renters are burdened — they always were — but that middle-income bands moved fastest. Renters earning $45,000–$74,999 saw burden rates nearly double since 2001, reaching just over 45% in 2023 (+22.7 pp over two decades, +7.7 pp since 2019). The $30,000–$44,999 band sits at 70% burdened. Higher-income renters ($75,000+) are still mostly unburdened at 13%, but that rate is up 3.3 pp since 2019 — evidence that even the high end of new Class A supply did not fully shield upper-middle renters in hot markets.

Composition followed the rates. Lower-income households fell from about 61% of all cost-burdened renters in 2001 to roughly half in 2023, while middle-income households rose to about 41% of the burdened population. Absolute counts still show 11.3 million burdened households under $30,000 — the largest block — but the political economy of “who is rent-burdened” now includes a much thicker middle.

Full-time work is no longer a reliable escape hatch. The share of fully employed renter householders with cost burdens climbed from under 25% in 2001 to 36% in 2023. Occupation cuts in the JCHS tables put personal/care services and food preparation above 50% burdened even among full-time workers — a reminder that wage floors in local service sectors did not keep pace with rent distributions after 2019.

Regions, states, and the rural floor

Census-region averages compress metro drama but clarify direction. In 2023, the West (52%) and South (50%) led; the Northeast (49%) sat close behind; the Midwest (45%) remained lowest. The South’s +4.2 pp rise since 2019 outpaced every other region. State ranks rhyme with the metro ladder: Florida at 59% leads the country, followed by California, Hawaii, and Nevada in the mid-50s. Arizona’s +8.0 pp jump since 2019 is the largest state delta JCHS highlights; Oregon and Georgia also cleared +5 pp. A handful of Plains states (North Dakota, South Dakota, Wyoming) improved by more than 2 pp and still print burden rates in the mid-30s — the national floor, not an affordable paradise.

Geography tiers make the same point without MSA labels. Largest metros average 51% burdened (+3.5 pp since 2019); other metros 48%; micropolitan areas 42%; rural areas 39%. Rural America’s lower rate still means nearly two in five rural renters are cost-burdened. Desks that treat rent burden as a coastal-only story are reading the wrong map.

Caveats and how to read the dashboard

1. ACS is a survey. Metro shares carry sampling error; year-to-year moves under ~1 pp can be noise, especially outside the largest MSAs.
2. Income is household income, not wages. Multi-earner households and roommate groups lower measured burdens relative to individual renters’ lived experience.
3. Gross rent includes utilities. Markets with high electric or heating costs can print higher burdens at the same contract rent.
4. 2015 metro comparables are desk joins. MSA boundary changes and ACS vintage quirks mean some 2015→2023 deltas are carried estimates, not official JCHS appendix reprints.
5. Asking-rent indexes are not ACS. Zillow/Apartment List cooling in 2024–25 can coexist with sticky ACS burdens until turnover resets the occupied stock.
6. Assistance is out of frame. HUD voucher and public-housing tenants appear in ACS, but unmet worst-case needs (JCHS cites millions of unassisted very-low-income renters) are a parallel ledger.

Use the dashboard’s region filter when you want to know whether a Florida-shaped ladder survives outside the South, and flip the sort lens to severe when residual income — not the 30% rule — is the decision variable. For one-line briefings: half of U.S. renters remain above 30% of income on rent and utilities, 27% are above 50%, and the hottest large-metro prints are Florida’s — Cape Coral at 65% and Miami at 63% — with most large markets still worse than in 2015.
