For all persons, CPI2009 provides the Consumer Price Index multiplier (available from the Bureau of Labor Statistics) to convert dollar figures to constant 2009 dollars. Multiplying dollar amounts by this variable (which is constant within years) will render them comparable across time and thus suitable for multivariate analysis.

For IPUMS MEPS, 2009 dollars represent data in 2009 as income and expenditures are asked about for the current year.

For more information on how to use CPI2009, please see the IPUMS MEPS User Notes on Consumer Price Index.
