2 Version 2 of this file was placed on this server on Thursday, January 22, 2004 due to an error found in the veterans weight.
4The Tenure items (HETENURE, HXTENURE) are available in DataFerrett, and are updated only in the months of January, April, July, and October for the previous quarter. Basic CPS files on the CPS FTP site do not include Tenure items. Users must obtain them via DataFerrett and append them appropriately. Tenure items are included on all of the CPS supplement files on the CPS FTP site.
5The January 2005 files were replaced (May 20, 2005).
6This file contains a second set of weights to be used in conjunction with the December 2007 original public use file. These weights are controlled to population estimates consistent with the new set of controls introduced in January 2008.
7The May 2008 data files were replaced (Aug. 4, 2008).
8The Nov and Dec 2009 data files were replaced to correct the values in HETELHHD, HETELAVL, and HEPHONEO (Jan. 28, 2010).
9June 10, 2010 - CPS Age Perturbation Issue - Please see the user note for a full explanation.
10May 18, 2011 - The January, February, and March 2011 basic CPS microdata are now available. A new age swapping procedure, implemented in January 2011, protects the confidentiality of individuals in sample.
11Feb 17, 2012 - We are no longer providing the standard Unix compression type. Most current Unix/Linux machines have zip or gzip utilities.
12April 3, 2012 - These files were replaced. Please see the User Note for a full explanation.

Tax variables: ACTC_CRD, AGI, CTC_CRD, EIT_CRED, FEDTAX_AC, FEDTAX_BC, FED_RET, FICA, MARG_TAX, MWP_VAL, STATETAX_A, STATETAX_B, TAX_INC, DEP_STAT, & FILESTAT.
