FHFA notes: The FHFA HPI is a broad measure of the movement of single-family house prices. The FHFA HPI is a weighted, repeat-sales index, meaning that it measures average price changes in repeat sales or refinancings on the same properties. FHFA describes its ZIP code indexes as developmental: they may be revised as new data arrive or methods change, and the index does not give a dollar value for any home.
ZIP code 17921 is in Schuylkill County, Pennsylvania, within the Pottsville, PA area. FHFA's index for it begins in 2001; through 2025 it stands at 235, meaning prices in repeat sales of the same homes are up +135.0% since 2001.
Over the ten years to 2025 the index rose +105.1%, about +7.4% a year: above Schuylkill County (+92.1%), well above Pennsylvania (+76.8%) and well above the national index (+85.0%). The change over 2024–2025 was +26.2%.
The index did not fall 5% or more from a peak between 2006 and 2012, which is unusual; small samples in a ZIP code can also mask movements.
Building activity is measured at county level: Schuylkill County authorised 214 housing units in the 12 months to August 2026, 1.5 per 1,000 residents, 67% of them single-family.

Decade by decade
| Decade | Change | United States | |
|---|---|---|---|
| 2010s (2010–2020) | +11.4% | +35.5% | |
| 2020s so far (2020–2025) | +69.6% | +47.0% |
FHFA reports each index with a value of 100 in its base period, the first year the area has enough transactions (2001 here). A decade's change is the index at the end of the decade divided by the index at the start, so it does not depend on the base year; the United States column covers the same years. Decades before 2001 are not shown.

From the Federal Housing Finance Agency's annual five-digit ZIP code house price index (all-transactions), last updated March 31, 2026.

The index tracks price changes for the same homes over time; it does not give a dollar value for any home.
