In order to meet data user demands, PPPs for years between benchmark periods are provided in the World Development Indicators.  These extrapolations are based on GDP growth rates. Different procedures are used by the Penn World Tables which bring in come cost of living data as well. In addition, PPPs are imputed for non benchmark countries.

Eric Swanson and Changqing Sun will lead the effort to document the methodology and seek improvements; the working group will include  E. Diewert, P. Rao, and K. Zieschang.
