After years of gathering data, Pasadena, Calif.-based Self Storage Data Services Inc. (SSDS) has introduced a tool that tracks site-level market conditions and operating results for self-storage. Through an exclusive arrangement with SSDS, Inside Self-Storage will publish the U.S. Self-Storage Performance Index (SSPI) quarterly.

The index allows operators and participants in the capital markets to track industry trends. It measures the health of the domestic market based on key operating statistics from facilities in the countrys 50 largest Metropolitan Statistical Areas (MSAs). Specifically, it uses the asking rental rates on 100-square-foot, climate-controlled units as the benchmark for industry revenues.

Source data is gathered from sources public (SEC filings of self-storage REITS) and private (surveyed and contributed). In the most recent quarter, data from more than 6,600 properties was used in the calculation of the SSPI, which represents a 39 percent sample of the known facilities in the top MSAs.
