Statewide Adjustment Factors

Note: This page contains historical data from CalRecycle’s statewide goal measurement prior to 2007 that estimated a diversion percentage. For 2007 and subsequent years, CalRecycle compares reported disposal tons to population to calculate per capita disposal expressed in pounds/person/day. This new goal measurement system is described in CalRecycle’s Goal Measurement: 2007 and Later web page.

This table shows adjustment method factors used to calculate the statewide diversion rate estimates: population, employment, and taxable sales. Through 2004, CIWMB (now CalRecycle) adjusted taxable sales for inflation using the Consumer Price Index (CPI). In 2005, the CIWMB began using the Taxable Sales Deflator Index (TSDI) to adjust taxable sales for inflation. A preliminary TSDI is used for the statewide diversion rate.

*The Board's Taxable Sales Deflator Index (TSDI) was used to remove inflation from taxable sales amounts used in statewide diversion rate estimates for 2005 and 2006. A preliminary TSDI is used for the statewide diversion rate. Prior to 2005, Consumer Price Index (CPI) was used. In 2004, the State Board of Equalization stated that its taxable sales deflator is a more accurate measure of inflation in taxable sale amounts. Because of this change in methodology, the statewide generation and diversion rate estimates for 2005 and 2006 are not directly comparable with prior year estimates.
