CRSP/Ziman REIT Data Series

CRSP/Ziman Real Estate Data Series


The CRSP/Ziman Real Estate Data Series represents a collaborative effort between the Richard S. Ziman Center for Real Estate at the UCLA Anderson School of Management and The Center for Research in Security Prices at the University of Chicago. The REIT data series is a unique research resource whose development merges CRSP's experience in academic-quality financial database and index creation with the Ziman Center's expertise in real estate markets and the collection of real estate data.

Combining stock price and returns data with carefully researched information regarding the population, characteristics, and history of REITs, the CRSP/Ziman database provides firm-specific information and indexes essential to analyses of REITS.

Daily and monthly indexes are computed with both equal- and value-weighting for subsets defined by type of REIT and the types of properties predominately held by equity REITs. This database includes several qualitative measures detailing market capitalizations, concentrations, and changes in index composition. These measures are useful in evaluating the index series during periods when they were thinly populated.
