Zillow Observed Rent Index (ZORI): A smoothed measure of the typical observed market rate rent across a given region. ZORI is a repeat-rent index that is weighted to the rental housing stock to ensure representativeness across the entire market, not just those homes currently listed for-rent. The index is dollar-denominated by computing the mean of listed rents that fall into the 35th to 65th percentile range for all homes and apartments in a given region, which is weighted to reflect the rental housing stock.

ZORI is created for three different categories: All homes, Single Family Residences, and Multi-Family Residences. For more detailed information, you can refer to the ZORI methodology.

Zillow Observed Renter Demand Index (ZORDI): A measure of the typical observed rental market engagement across a region. ZORDI tracks engagement on Zillow’s rental listings to proxy changes in rental demand. The metric is smoothed to remove volatility.

ZORDI is created for different categories including All homes, Single Family Residences, Condo and Multi-Family Residences at national and MSA levels.
