Benefits Cliff in Tennessee: What It's Costing 199,000 Families Across 95 Counties
A single mother in Anderson County earns $14 an hour. She gets offered a raise to $17. If she takes it, she loses SNAP, childcare subsidies, and Medicaid within the same income band—a combined benefit loss that can exceed $8,000 a year. The raise nets her $6,240 before taxes. She does the math. She turns it down.
This is the benefits cliff—sometimes called the welfare cliff or cliff effect. It is the point where earning more money triggers the loss of public benefits worth more than the wage increase. And in Tennessee, it is happening at scale.
The analysis below covers all 95 Tennessee counties using Census ACS 2024 data, federal and state benefit program rules, and peer-reviewed research on cliff avoidance behavior. The numbers are published as part of the CLIFF Index, a free county-level benefits cliff diagnostic covering all 3,144 U.S. counties.

The Scale of the Problem
Nearly 200,000 Tennessee families earn between 100% and 200% of the Federal Poverty Level—the income range where SNAP, Medicaid, childcare subsidies (Families First), EITC, and housing assistance all phase out. These families are not in poverty. They are just above it, in the zone where a raise can make them worse off.
Research from Washington University's Center for Social Development (2025, n=2,511) found that 22% of workers in this income range actively avoid advancement—turning down raises, refusing additional hours, or declining promotions—specifically to keep their benefits. But Urban Institute analysis shows fewer than 6% would actually lose net income from a typical raise. The gap between fear and reality is where the economic damage happens.
The 10 Counties Losing the Most
These are the Tennessee counties with the highest estimated wage suppression from benefits cliff avoidance—the dollar amount the local economy never sees because workers limit their earnings.
| County | Cliff-Zone Families | Cliff Zone % | Wage Suppression |
|---|---|---|---|
| Shelby County | 28,145 | 19.6% | $20.5M |
| Davidson County | 18,227 | 16.0% | $13.3M |
| Knox County | 12,158 | 16.7% | $8.9M |
| Rutherford County | 10,046 | 15.9% | $7.3M |
| Hamilton County | 8,317 | 14.3% | $6.1M |
| Montgomery County | 7,469 | 18.2% | $5.4M |
| Sullivan County | 4,709 | 18.5% | $3.4M |
| Sumner County | 4,471 | 12.3% | $3.3M |
| Bradley County | 3,671 | 19.8% | $2.7M |
| Sevier County | 3,608 | 22.3% | $2.6M |

Shelby County (Memphis) alone has over 28,000 families in the cliff zone, with an estimated $20.5 million in annual wage suppression. Davidson County (Nashville) follows at $13.3 million. But the proportional impact is often more severe in smaller counties.
The Counties Hit Hardest by Percentage
The raw numbers tell one story. The percentages tell another. These are the Tennessee counties where the largest share of the population is in the cliff zone—where the structural problem is deepest relative to community size.
Lake County, Tennessee's smallest, has nearly 30% of its population in the cliff zone. Overton County, Fentress County, and Scott County—all in the Upper Cumberland region served by Empower Upper Cumberland—rank among the top 10.
Why This Matters Now
Tennessee invested $175 million in TANF funds for cliff mitigation through the Our ChanceTN pilot, serving approximately 900 families across 7 counties. The bipartisan Upward Mobility Act (H.R. 6949) proposes capping marginal effective tax rates at 50%—exactly the metric the CLIFF Index computes for every county. Twelve states are already piloting cliff reduction strategies through APHSA.
The policy momentum is real. But policy without data is guesswork. Community leaders need to know which counties are most affected, how much the cliff is costing their local economy, and where intervention will have the highest return.
The CLIFF Index provides this data—free, for every county, with full methodology and source citations in each report.
Applications for This Data
Every county's CLIFF Index page includes a downloadable PDF report with cliff zone data, economic impact estimates, benefit program analysis, and evidence-based strategies. Community leaders are using this data to:
- Strengthen grant applications—cite county-specific cliff data in CSBG community needs assessments, WIOA plans, and foundation proposals.
- Brief elected officials—translate the cliff into a dollar amount the county is losing.
- Quantify labor market effects—show how the cliff contributes to the labor shortage employers report.

Full methodology is available on each county's CLIFF Index page. Cliff zone families are counted directly from Census Table B17026 (families at 100–199% FPL). Wage suppression estimates apply CSD/WashU avoidance rates to the cliff-zone population, adjusted by Atlanta Fed benefit parameters. These are estimates, not enrollment data.
