This is a 6-digit numeric variable with 3 implied decimal places.

Description

CPI2009C provides the CPI-U multiplier (available from the Bureau of Labor Statistics) to convert dollar figures to constant 2009 dollars for variables whose reference year is the survey year (SALARY). Multiplying dollar amounts by this variable (which is constant within years) will render them comparable across time and thus suitable for multivariate analysis.

For variables that have a reference year of the previous year (EARN and HHINC), users should use CPI2009P to convert dollar figures to constant 2009 dollars.

For more information on how to use CPI2009C and CPI2009P, please see the SESTAT inflation adjustment page.
