CPI99 is a 4-digit variable with three implied decimal places.
CPI99 provides the CPI-U multiplier (available from the Bureau of Labor Statistics) to convert dollar figures to constant 1999 dollars. (This corresponds to the dollar amounts in the 2000 CPS, which inquired about income in 1999.) Multiplying dollar amounts by this variable (which is constant within years) will render them comparable across time and thus suitable for multivariate analysis.
For more information on how to use CPI99, please see the IPUMS inflation adjustment page.
This variable is fully comparable across years and samples.
