Debt statistics can look contradictory when the same words are used for different populations or measurements. DebtData keeps definitions explicit so that totals, averages, rates, and borrower counts are compared on a like-for-like basis.
Outstanding Balance
An outstanding balance is the amount reported as still owed at a specified point in time under the rules of the source. Depending on the dataset, the balance may include principal, interest, or both. The source definition determines what is included.
Federal Student Loan Portfolio
The federal student loan portfolio covers loans included in Federal Student Aid reporting. It should not be described as the total value of every student loan in the United States when private or other nonfederal balances are outside the dataset.
Total Student Loan Debt
Total student loan debt can refer to a broader consumer-credit or financial-account measure. The exact meaning depends on the source. DebtData identifies the source and coverage rather than assuming that every national total measures the same accounts.
Borrower and Recipient
A borrower is generally the person legally responsible for a loan. Some Federal Student Aid reports use the term recipient. These concepts can differ in specific programs, including Parent PLUS borrowing, so DebtData follows the terminology of the source when that difference matters.
Average Balance per Borrower
An average balance per borrower is calculated by dividing a compatible outstanding balance by the corresponding borrower or recipient count for the same population and period. An average created from a balance in one dataset and a borrower count from another can be misleading and is not treated as a valid national average.
Debt at Graduation
Debt at graduation measures cumulative borrowing for a defined graduating cohort. It is not the same as the current outstanding balance of all people with student loans. Some graduation measures include only borrowers, while others average debt across all graduates.
Average and Median
The average is the arithmetic mean. The median is the midpoint of a distribution. A median can be substantially different from an average when a smaller number of borrowers have very high balances. DebtData does not substitute one for the other.
Delinquency
Delinquency generally means that a required payment is past due but the loan has not necessarily reached the source’s definition of default. Delinquency thresholds vary by dataset, so the number of days past due and the population measured should be stated when available.
Default
Default is a more serious nonpayment status defined by the applicable loan program or dataset. A point-in-time count of borrowers already in default is different from a cohort default rate that follows a specific group of borrowers over a defined measurement window.
Repayment, Deferment, and Forbearance
Repayment describes loans in a payment status under the source’s classification rules. Deferment and forbearance are temporary statuses in which required payments may be postponed or reduced under specified conditions. A borrower can have multiple loans in different statuses, so some administrative counts can overlap.
Interest Rate
An interest rate is the annual rate applied under the terms of a loan. Federal student loan rates can vary by loan type and disbursement year. A current statutory rate should not be presented as the average rate paid by every borrower with an outstanding loan.
Nominal and Inflation-Adjusted Dollars
Nominal dollars are reported in the value of money for the period measured. Inflation-adjusted dollars convert earlier values into the purchasing power of a stated base year. DebtData labels the base year when an inflation adjustment is used.
Percentage Change
Percentage change measures the difference between two compatible values relative to the earlier value. A percentage-point change is different: it measures the arithmetic difference between two percentages.
Geography
Debt by state can be based on borrower residence, institution location, or another geographic rule. These are not interchangeable. DebtData follows the geographic definition used by the source and avoids describing borrower-location data as school-location data.
