Decode the unit before interpreting the change
A denominator is the group or total used to calculate a rate. Ten late accounts out of 100 accounts is 10%; that is a rate of accounts, not necessarily a rate of people or dollars.
| Measure | What it counts | Common misreading |
|---|---|---|
| Outstanding balances | Dollars owed at a date | A rise proves more people are in distress. |
| New delinquency | Accounts or balances entering a late-payment category during a period | It is the same as all accounts already late. |
| Serious delinquency rate | A specified late category divided by a specified population or balance | The percentage refers to people when it actually refers to dollars. |
| Bankruptcy filings | Cases filed during a period, under defined chapters and categories | Each case equals one affected person or one settled debt. |
| Inflation | Change in a defined price index | The national average exactly matches a household’s expenses. |
The same economy can show growing balances and improving delinquency rates. More borrowing, repayment, lenders writing balances off as losses, population changes and the composition of loans can all affect the totals.
Use the source that measures the question
- Household credit balances and delinquency
- The New York Fed Household Debt and Credit report is a starting point. Read the report’s product definitions, coverage, observation period and technical notes before comparing series.
- Consumer prices
- The Bureau of Labor Statistics CPI program measures price changes for defined consumer baskets. Choose the relevant index, geography and whether the figures are adjusted for predictable seasonal patterns.
- Court filings
- Use the judiciary’s statistical releases and the table’s business/nonbusiness and chapter definitions. Case counts do not capture everyone experiencing financial hardship.
- Lending conditions
- Use an identified central-bank survey or official series, keeping lender-reported standards separate from actual borrower approvals.

Write a comparison someone else could reproduce
A complete statistical sentence
For [population and geography], [measure and unit] was [value] during/as of [observation period], according to [publisher, table and release date]. The comparison uses [matching prior period], with [revision or method limits].
Check whether the change is in percentage points or percent. A hypothetical rate moving from 4% to 5% rises by one percentage point and 25% relative to its starting rate. Those statements describe the same arithmetic with different units.
Compare seasonally adjusted observations with like observations. Separate raw dollar amounts from amounts adjusted for changes in purchasing power. Do not infer a racial, income or age-group result from a national average, or compare a small subgroup estimate without considering uncertainty and sample coverage.
Finally, use the statistic for the question it can answer. National debt conditions may explain the environment around a household; affordability still depends on that household’s income, essential expenses, assets, legal exposure and actual account terms.
Changes in definitions can break an apparent trend. Before joining two series, check whether reporting practices, coverage or classification changed. A revision may improve the estimate without representing a new event in the economy. If comparability is uncertain, describe the break instead of drawing a smooth line across it.
