Motivation: Our source, the Hungarian Central Statistical Office (HCSO), reports an index of pure price change in existing homes, but only in not seasonally adjusted (NSA) terms.

Response: For analytical convenience and international consistency, we have created a seasonally adjusted (SA) counterpart series.

Properties: Properties are generally identical to the NSA fundamental: Indexed to 2015=100, starts at 2007Q1. Expect our SA series to be revised with each update. Supplemental series of this kind are marked in their source metadata with a secondary citation of "Moody's Analytics Adjusted."

The series resides in the historical catalog (Hungary » Real estate » Residential » Prices » House price index (HCSO)) and is:

• HPIXPAQ.IHUN = Residential real estate: Price - Existing - Pure price change, (Index 2015=100, SA)

Method:

1. Adjust the reported series using the U.S. Census Bureau's X-13 ARIMA program.
