Item Structure and Publication Changes to the Consumer Price Indexes for January 2010

Effective with the release of CPI data for January 2010 scheduled for Friday, February 19, the BLS will introduce several item structure and other publication changes into the CPI.

Shelter The expenditure weight for second homes will be moved from Lodging away from home to a new, unpriced stratum under the Owners’ equivalent rent expenditure class. As such, the expenditure class index for Owners’ equivalent rent will now include both primary and secondary homes, and the title of that expenditure class index will change from Owners’ equivalent rent of primary residences to Owners’ equivalent rent of residences. Both the expenditure class (Owners’ equivalent rent of residences), and the Owners’ equivalent rent of primary residence stratum within it, will be published.
