CPI99
CPI-U adjustment factor to 1999 dollars

Description

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 census, which inquired about income in 1999. Multiplying dollar amounts by CPI99 (which is constant within years) will render them comparable across time and thus suitable for multivariate analysis.

See the IPUMS inflation adjustment page for more information on how to use CPI99.
