Understanding US National Case-Shiller House Price Index (NSA)
Tracks price movements of single-family homes across the United States by comparing repeat sales of the same real estate. This repeat-sales methodology helps limit distortion from changes in the composition of sold houses, though it does not directly represent new construction, condominiums, or all property types. Compared to composite indices grouped by metropolitan area, the national scope covers more markets and is less dominated by a few large cities.
Unadjusted series retain seasonal purchasing patterns, so month-on-month changes may reflect weather, holiday schedules, and transaction timing. Year-on-year comparisons are generally more appropriate for identifying price trends. The index shows relative prices compared to a base period, not average selling prices; an increase in the index does not imply that every home appreciated at the same rate. Recent results may be updated as additional transactions are recorded.
Frequently asked questions
- Does a rising index mean the prices of all houses are increasing?
- No. This is an aggregate measure derived from eligible transactions, while individual sectors and properties may move differently.
- Why is it preferable to prioritize year-over-year comparisons?
- The unadjusted series still contains seasonal effects, so comparing with the same period last year helps reduce noise from weather and transaction schedules.
- Is this index equivalent to the average home sale price?
- No. It measures price changes through repeat sales rather than dividing the total transaction value by the number of homes sold.
