What Is Inflation?
Inflation is the rate at which the general level of prices for goods and services rises over time, reducing the purchasing power of each dollar. Measured primarily through the Consumer Price Index (CPI), inflation directly erodes household budgets — when prices rise faster than wages, families fall behind on bills, deplete savings, and accumulate debt, driving the financial distress the American Distress Index tracks.
Key Facts
- The Bureau of Labor Statistics measures inflation through the Consumer Price Index (CPI), which tracks price changes across approximately 80,000 items in 200 categories — the CPI-U (All Urban Consumers) covers about 93% of the U.S. population
- Cumulative inflation since January 2020 exceeds 22%, meaning goods that cost $100 in early 2020 now cost approximately $122 — but category-specific inflation varies dramatically: groceries are up 33%+, auto insurance 55%+, and shelter costs remain elevated at 3.3% year-over-year
- The Federal Reserve targets 2% annual inflation using the PCE (Personal Consumption Expenditures) price index rather than CPI — when inflation exceeds this target, the Fed raises the federal funds rate, which increases mortgage rates and credit costs for households
- Core inflation (excluding volatile food and energy) is tracked separately because food and energy prices can spike temporarily — but for households in financial distress, food and energy are unavoidable expenses that consume a larger share of income
- The ADI tracks inflation through multiple cost pressure indicators including CPI, healthcare CPI premium over core, auto insurance CPI premium, grocery cumulative price increases, and the wage-CPI spread — together these capture how inflation differentially burdens distressed households
How Is Inflation Measured?
The Bureau of Labor Statistics (BLS) measures inflation primarily through the Consumer Price Index (CPI). Each month, BLS data collectors record prices for approximately 80,000 items across 200 categories in 75 urban areas. The CPI weights these prices according to consumer spending patterns derived from the Consumer Expenditure Survey:
- CPI-U: The most widely cited measure, covering all urban consumers (93% of the population). When news reports say "inflation is 2.7%," they typically mean the 12-month change in CPI-U.
- CPI-W: Covers urban wage earners and clerical workers — used to adjust Social Security benefits (COLA adjustments).
- Core CPI: Excludes food and energy because their prices are volatile. The Fed watches core inflation more closely for policy decisions.
- PCE: The Federal Reserve's preferred measure, produced by the Bureau of Economic Analysis. It captures a broader set of expenditures and accounts for substitution effects when consumers switch to cheaper alternatives.
Why Does Inflation Hit Distressed Households Harder?
Inflation is not experienced equally. Low- and moderate-income households face disproportionate impact for several structural reasons:
- Higher food share: Households in the bottom income quintile spend approximately 30-35% of income on food, compared to 8-10% for the top quintile. When grocery prices rise 33% cumulatively, the impact is three to four times greater for lower-income families.
- No substitution buffer: Wealthier households can trade down (name brand to generic, restaurant to home cooking). Households already at the cheapest options have nowhere to substitute.
- Fixed-cost squeeze: Rent, insurance, and utilities are non-negotiable. When these rise, the only place to cut is food, healthcare, or debt payments — creating the delinquency cascade the ADI tracks.
- Wage lag: Even when nominal wages rise, they often lag inflation for months or years. The ADI's wage-CPI spread indicator tracks this gap directly.
Inflation and the American Distress Index
The ADI's Cost Pressure component (15% weight) captures inflation's household impact through multiple indicators:
- Healthcare CPI premium: How much healthcare inflation exceeds core inflation — currently running at a premium, meaning medical costs outpace general price increases
- Wage-CPI spread: The gap between average hourly earnings growth and CPI growth — when negative, workers are losing purchasing power
- Grocery cumulative index: Total food price increase since 2020 — prices don't come back down when the inflation rate drops, a concept called "price level permanence"
- Auto insurance premium: Auto insurance inflation running well above core CPI, adding to household cost burden
Critically, when the Federal Reserve raises interest rates to fight inflation, it simultaneously increases mortgage rates and credit card APRs — creating a double squeeze where prices are high AND borrowing costs are high. This is the mechanism through which inflation transmits into the ADI's Financial Conditions component.
The Price Level Problem
A common misconception is that falling inflation means prices are going down. A decline from 9% to 3% inflation means prices are still rising — just more slowly. The cumulative price level since 2020 remains permanently elevated. Grocery prices that rose 33% are not returning to pre-pandemic levels even as the rate of increase slows. This "price level permanence" means household budgets remain under pressure even after inflation rates normalize, which is why the ADI continues to track elevated cost pressure despite lower headline inflation numbers.
State-by-State Variations
While inflation is measured nationally, regional price levels vary significantly by metro area and state — driven by housing costs, energy prices, state taxes, and local market conditions.
| State | Key Difference |
|---|---|
| California | Consistently above-average inflation due to high housing costs and state regulations. Los Angeles and San Francisco metro areas regularly post CPI increases 0.3-0.5 percentage points above the national average. |
| Texas | Generally tracks national inflation closely but experienced outsized energy cost swings during the 2021 winter storm (Uri) and oil price volatility. No state income tax means households have more gross income but face property tax pressure. |
| Florida | Above-average shelter inflation due to rapid population growth and insurance cost increases. Property insurance premiums have risen 40-60% since 2020, adding to effective household inflation beyond what CPI captures. |
| Mississippi | Lower absolute price levels but inflation hits harder because median household income ($52,985) is the lowest in the nation. A 22% cumulative price increase on a lower income base creates deeper financial distress. |
| New York | New York City metro area has consistently higher cost of living but inflation rates have roughly tracked national figures. State minimum wage increases ($16/hr NYC) partially offset price increases for lower-wage workers. |
Frequently Asked Questions
What is the current U.S. inflation rate?
As of early 2026, the annual CPI-U inflation rate is approximately 2.7%, down from its peak of 9.1% in June 2022. However, cumulative prices remain 22%+ above January 2020 levels. Core inflation (excluding food and energy) runs slightly higher. The Federal Reserve's 2% target has not yet been sustainably achieved.
Why do prices stay high even when inflation comes down?
Inflation measures the rate of price increase, not the price level. When inflation drops from 9% to 3%, prices are still rising — just more slowly. For prices to actually fall, you need deflation (negative inflation), which is rare and brings its own economic problems. The 33%+ grocery price increase since 2020 is permanent.
How does inflation affect mortgage payments?
Fixed-rate mortgages are protected from inflation — your payment stays the same. But adjustable-rate mortgages (ARMs) rise when the Fed raises rates to fight inflation. New borrowers face higher rates. And inflation increases property taxes, insurance, and maintenance costs — even fixed-rate borrowers see their total housing cost rise.
What is the difference between CPI and PCE inflation?
CPI tracks a fixed basket of goods that consumers buy. PCE (Personal Consumption Expenditures) is broader, includes employer-paid costs like health insurance, and adjusts for consumer substitution. The Fed prefers PCE. CPI typically runs 0.3-0.5 points higher than PCE.
How does inflation connect to the American Distress Index?
The ADI tracks inflation through its Cost Pressure component (15% weight), using indicators like the healthcare CPI premium, wage-CPI spread, grocery cumulative prices, and auto insurance premium. When prices rise faster than wages, households deplete savings and fall behind on debts — directly feeding the Buffer Depletion and Debt Stress components.
