    Known data issue.

    • 177 person records in the 2024 March BMS sample have malformed values of MARBASECIDP due to problems in the original CPS data.

    New feature release.

    • New and improved SDA datasets now available for online data analysis! Users can now analyze datasets that include the entirety of the ASEC and the BMS collections, as well as individual complete datasets for each supplement topic.

    Expanded variables.

    • MARBASECIDH and MARBASECIDP, the linking variables needed to link households and persons (respectively) in the March basic sample to their records in the ASEC, have now been added for the March 2022, 2023, and 2024 samples.

    Fixed data.

    • We found and corrected an error in the adjustment factor for 2021 in our adjust monetary values feature. The previous incorrect factor was 0.7821177753; the corrected factor is 0.804723770159058. Users who applied monetary adjustment to files that include 2021 data should resubmit their extracts to get updated values. Alternatively, they can re-adjust values directly by multiplying adjusted 2021 values by 1.028903569. Note that the reference year for all variables that are currently eligible for monetary adjustment is the same as the survey year so only data from 2021 need to be adjusted.

    • MBPL in November 2009 previously specified respondent's birthplace rather than mother's birthplace. This correction also affects NATIVITY.
    • FBPL in October 2009 previously specified respondent's birthplace rather than father's birthplace. This correction also affects NATIVITY.
    • EDUC has changed for basic monthly samples from 1976-1988. Specifically, values previously coded as 71 are now coded as 60. Many values previously coded as 73 are now coded as 72.

    • WTFINL weights have changed for April and June 2001. We had previously replaced the original weights for April and June 2001 with weights based on 2000 population controls. Unfortunately, the April and June weights based on 2000 population controls were problematic, yielding population totals that are far too low. To address this issue, we have reverted back to delivering the original weights delivered with the April and June files.
    • An error was corrected in TCUT in the May 2010 sample.
    • An error was corrected in TAMSMK in the January 2011, January 2007, and November 2003 samples.

October 30, 2012

    Edited variables.

    • The widths for the following income and tax variables have been increased to accommodate changes to new topcoding procedures beginning in 2011:
    • Income variables: Respondents under age 14 or 15 (depending on the sample) were previously coded to NIU on all income variables. We continue to do this in the cases where no income is reported; when non-zero income is reported, we now retain the original income values.

October 23, 2012

    Edited variables.

    • BPL, MBPL, FBPL: American Samoa and Samoa were erroneously grouped in samples January 1994 to October 2008. American Samoa is now grouped under US Outlying Areas, and Samoa is now grouped under Oceania. Albania was erroneously listed under Yugoslavia in all samples.
    • INCOTHER: NIU and topcodes were previously assigned erroneously in the March 2011 and 2012 samples.

    • RELATE and family interrelationship variables in the 1968-1975 March samples were updated.
    • Errors in the RELATE variable for the 1968-1975 March samples have been corrected. In previous versions, RELATE excluded relationships between household members and children under the age of 14.
    • We used additional information from the original CPS data to identify family relationships between children and adults in the household, improving the accuracy of information in the following variables: RELATE,  MOMLOC,  STEPMOM,  MOMRULE,  POPLOC,  STEPPOP,  POPRULE,  SPLOC,  SPRULE,  FAMSIZE,  NCHILD, NCHLT5,  FAMUNIT,  ELDCH,  YNGCH, and NSIBS.
    • Fixes were made to tax and non-cash benefit variables: Errors in FEDRETIR were fixed for the March 1992-2011 samples. The previous version of this variable truncated values at four characters wide; the current version is five characters wide. Errors in STAMPVAL for the March 2010 sample were corrected.

February 29, 2012

    Added variables.

    Edited variables.

    • OCC was widened from three digits to four for samples from January 2003 forward for consistency with Census occupation codes.
    • Fixes were made to YRIMMIG to correctly classify recent immigrants into appropriate year ranges.
    • We have discovered errors in poverty variables drawn from the alternative poverty files released by the Census Bureau. We are working to address these errors and will release the alternative poverty variables as soon as we can.

September 22, 2011

    New data soon.

    • The summary health insurance variables (constructed by SHADAC) are not yet available for March 2011; they will be released in the coming months.

    • Posted new basic monthly data for January 1998 through December 1999.

May 12, 2011

    Edited variables.

    • The code for "not reported" values on occupation (OCC) in the 1972-1982 samples was changed from 1995 to 1994.
    • The recodes for veteran status (VETSTAT) in the 1976-1987 samples were changed to be consistent with surrounding samples.
    • IPUMS recodes of earner study variables (also known as "outgoing rotation group" variables) have changed. According to Technical Paper 66, issued jointly by the Census Bureau and the Bureau of Labor Statistics, individuals eligible for the earner study are civilians age 15 and older in rotation groups 4 or 8 who are not self-employed. In any given month, approximately 1/4 of the CPS sample is in the earner study and each household should appear in the earner study exactly twice. For certain earner study variables, we had imposed age restrictions excluding respondents under age 15 and respondents in the armed forces. In this data release, we remove these universe restrictions. Potentially affected variables include UNION, EARNWT,  EARNWEEK,  HRSWORK,  UHRSWORK, and PAIDHOUR. Based on documentation from Unicon and NBER, and after an inspection of the original CPS data, we recommend that users impose the CPS eligibility restrictions in any analyses of earner study variables.
    • The previous data release truncated values of veteran's most recent period of service (VETLAST). This problem is fixed in the current data release.
    • The universe for worked full or part time last year (FULLPART) has been expanded to include respondents who worked fewer than 14 weeks last year.
    • The coding scheme for education (EDUC) was modified to distinguish between 4 and 5 years of college. Codes 120 and 121 were added; codes 112-115 changed to 122-125.

    Expanded variables.

    • Codes for class of worker (CLASSWKR) were changed and expanded. Codes now include 21 (Wage/salary, private), 22 (Private, for profit), and 23 (Private, nonprofit). Codes 22 and 23 are unavailable in March supplement samples.

November 6, 2010

    Added variables.

    • Summary health insurance variables  are now available for the 2010 sample. Created by the State Health Access Data Assistance Center at the University of Minnesota, these variables smooth out several measurement differences across the various years of data and yield a consistent and easy-to-use set of health insurance variables.
    • Six new variables measuring family relationships are now available for the 2007-onward samples. These variables identify respondents' spouses (ASPOUSE), cohabiting partners (PECOHAB), mothers (PELNMOM), and fathers (PELNDAD), as well as the specific relationship (biological, step-, or adoptive) of mothers (PEMOMTYP) and fathers (PEDADTYP). Because they are based on survey items, they are likely more accurate than the IPUMS pointers SPLOC,  MOMLOC, and POPLOC. For more information, see the variable descriptions.
    • Different sources of veteran income (GOTVDISA,  GOTVEDUC,  GOTVOTHE,  GOTVPENS, GOTVSURV) are now available for the 1988 sample.

    Expanded variables.

    • Replicate weights (REPWT,  REPWTP) are now available for the 2010 sample. These contain full information about the complex sample design of the CPS and can be used to generate estimates of standard errors directly from the data. For more information, see our CPS replicate weight page.
    • Information on respondents' COUNTY of residence is now available for the 1996-onward samples. Users are cautioned that not all counties can be identified due to confidentiality restrictions, so the CPS should not be used to generate county-level statistics.

September 29, 2010

    Edited variables.

    • There are new categories available for year of immigration (YRIMMIG). However, the codes for YRIMMIG still reflect the latest possible year that the respondent immigrated.
    • Several items on which IPUMS welfare variables are based have been removed from the survey and are now unavailable. Of the welfare variables, only receipt of WIC (GOTWIC) remains. (KIDCNEED, identifying children who needed care while their parent(s) worked, is available according to CPS documentation, but is not available in the published data.)
    • Updated data are also available for CMBEG (an alternative measure of poverty) in the 2009 CPS; most respondents were erroneously classified as having family incomes of more than five times the federal poverty level. Users who downloaded this variable previously should revise their extract.

    Added variables.

    • Two allocation flags--one for RACE (QRACE) and one for HISPAN (QHISPAN) are now available. QHISPAN has not been available before, while QRACE was available in a less detailed form and has been expanded to two digits.

    New data soon.

    • Several variables measuring non-cash benefits and after-tax income have been withheld by the Census Bureau until the release of official reports on alternative income and poverty measures. These will be released as they become available, as will the alternative poverty measures themselves.
    • The Summary health insurance variables (constructed by SHADAC) are not yet available; they will be released in the coming months.
    • The CPS replicate weights (calculated by the Census Bureau) were released too late to be included in this update, but IPUMS will include them as soon as possible.

    Updated extract system.

    • Finally, our extract system has been improved for enhanced performance and a more intuitively understandable interface. Click here for a summary of the changes, or see our instructions page for more information.

June 25, 2010

    Edited samples.

    • The previous 2001 CPS has been replaced with the 2001 SCHIP expansion file, which contains data on 98,015 households and 206,639 persons--about 50 percent more households and 70 percent more persons than the previous version. TheSummary health insurance variables are now available for 2001, although other variable availability is unchanged.

    Added variables.

    • A new variable, CPI99, gives the Consumer Price Index for all urban consumers (CPI-U) to convert any dollar amount into constant 1999 dollars. For more information on how to use this variable, see this page.
    • Five variables are now available on the source of unearned income (INCUNERN) in the 1966 and 1967 samples: GOTSS,  GOTINT,  GOTDIVID,  GOTRENT, and GOTWELFR. Because data on the amount of unearned income does not distinguish among the sources of unearned income, these variables contain information available nowhere else for these samples. However, users are advised that these variables may be inconsistent with INCUNERN.
    • PROPTAX is now available for the 1992-2003 samples.

    Edited variables.

    • YRIMMIG, previously a three-digit code of intervalled years, is now a four-digit year that represents the latest possible year that the respondent could have immigrated to the U.S.
    • WKSUNEM1 and WKSUNEM2 contained incorrect data in the 1988 sample. They now contain the correct codes.

    Edited documentation.

    • Miscellaneous clarifications and corrections to documentation.

March 2, 2010

    Added variables.

    • New Summary health insurance variables are available. Constructed by the University of Minnesota's Summary health insurance variables(SHADAC), these variables smooth over several temporal inconsistencies in the CPS's measurement of health insurance and make several improvements, most notably with the imputation of verified insurance data for the 1988-1999 period. They largely mirror the measurement of health insurance in the 2008-onward American Community Survey and therefore provide a convenient set of summary variables to easily analyze trends in insurance coverage across time. IPUMS-CPS thanks SHADAC staff for providing these variables and for their assistance in developing documentation.
    • New variables have also been posted for the 2009 CPS that were not available when the data were originally released. They include the  alternative poverty measures along with a new variable for 2009 (STIMULUS) describing individuals' income from the economic stimulus package passed in 2008. Finally, the after-tax variables are now available as well: Newly-released household variables are STAMPVAL,  HOUSRET, and  PROPTAX; Person variables are  ADJGINC, DEPSTAT,  EITCRED,  EMCONTRB,  FEDRETIR,  FEDTAX, FEDTAXAC,  FICA,  FILESTAT, MARGTAX,  PMVCAID,  PMVCARE,  STATETAX,  STATAXAC, and TAXINC. Additionally, STAMPVAL is no longer censored by the Census Bureau at $9,999; the new topcode is $19,999. CAPGAIN and CAPLOSS are no longer part of the alternative poverty model and are not included in the 2009 CPS PUMS file.
    • Alternative poverty measures are also now available for the 2009 CPS. These measures were developed by the Census Bureau to incorporate information on medical out-of-pocket costs, geographic differences in the cost of living, and alternative methods of adjusting poverty thresholds for inflation.  For details, see the alternative poverty measures.

    Edited variables.

    • The main education variable has been streamlined to parallel as much as possible its measurement in IPUMS-USA data. EDUCREC has been replaced with EDUC, which contains all information in the original variables. HIGRADE contains additional detail on grade attendance (EDUC, in contrast, informs only about completion) and has been retained. Although EDUC99  is redundant with EDUC, it is also retained because it contains simpler coding that may be of use to users analyzing only 1992-onward data.
    • Negative replicate weight values (REPWT  and REPWTP) are no longer automatically recoded to zero, and more information about working withreplicate weights.in the CPS is now available on our replicate weights page.

September 30, 2009

    Added variables.

    • Added replicate weights, recently released by the Census Bureau, to the 2005-2009 CPS samples. Replicate weights can be used to estimate standard errors of sample statistics directly from the data. For more information, please see the REPWTP variable description. Users should be aware that selecting replicate weights will add 160 additional variables to extracts.

September 11, 2009

    Added variables.

    • Seven new disability variables: DIFFHEAR,  DIFFEYE,  DIFFREM,  DIFFPHYS,  DIFFMOB,  DIFFCARE, and  DIFFANY. These mirror the 2008 American Community Survey data, which will be released in late October.
    • Industry codes (IND) now use the 2007 Census Bureau classification.There are no major substantive differences in the meanings of the categories, although some labels have changed. Only one code is different: industry codes of 6675 (Internet publishing and broadcasting) in the 2003-2008 CPS data have been shifted to 6672 (Internet publishing and broadcasting and web search portals) in the 2009 CPS data.

    Edited documentation.

    • Documentation has been updated for the health insurance variables PRIVWHO1 (renamed to DPWHO1),  PRIVWHO2 (renamed to DPWHO2),  GRPWHO1, and GRPWHO2, which give the line number (LINENO) of the policyholder if one is covered by a privately purchased or employer-based insurance policy. Although previous documentation stated otherwise, the universe for these variables does not include policyholders themselves, so these variables will not have the same value as LINENO for policyholders.

    New data soon.

    • All other variables from the 2008 CPS remain the same, with the exception of non-cash benefits and tax variables as well as alternative poverty measures. These will be released in the IPUMS-CPS shortly after the Census Bureau releases them, most likely in early 2010.

June 19, 2009

    Added variables.

    • CONTPOV, available from 1968 onwards, gives one's total family income (FTOTVAL) expressed as a percentage of the poverty threshold for that family (CUTOFF). It is comparable to the POVERTY variable in IPUMS-USA.
    • Twelve experimental poverty measures are now available from 2002 onwards. These measures were developed by the Census Bureau to incorporate information on medical out-of-pocket costs, geographic differences in the cost of living, and alternative methods of adjusting poverty thresholds for inflation. For details, see the alternative poverty measures page.

    Edited variables.

    • The new versions also include three corrections to the FAMUNIT coding. In each of the 1962-1994 samples, FAMUNIT has generally changed for less than 0.5 percent of the cases. In each of the 1995-2008 samples, FAMUNIT has changed for 1-2 percent of the cases. Because  FAMSIZE and  NFAMS incorporate information from FAMUNIT, all persons in households where someone has a new FAMUNIT code may have different values for FAMSIZE and NFAMS, even if their own FAMUNIT code has not changed. In practice, though, very few persons have different FAMSIZE and NFAMS values in the 1962-1994 data.
    • The categories of EDUC99 have been altered to conform to the recent IPUMS-USA revision of this variable. Codes of 0-11 remain identical, the code of 12 is now an empty placeholder, and former codes of 12-17 have been shifted to 13-18. This change applies to the codes only; there has been no substantive change in the data.

    Edited documentation.

    • In households where the head is not the first person record, the first person record and any persons linked via MOMLOC, POPLOC, or SPLOC to the first person record were grouped with the primary family (FAMUNIT = 1) because of a programming error. From 1976 to 1993 and from 2006 to 2008, the head was always listed first in the household, and this particular correction does not affect these samples. In other samples, though, unrelated individuals are occasionally listed first; and they and their own relatives were mistakenly given FAMUNIT codes of 1.
    • FAMUNIT codes of 1 are now reserved exclusively for persons with a RELATE code of less than 1100 and any individuals linked to them by birth, marriage, or adoption. Thus household fragments now receive FAMUNIT codes of 2; they received codes of 1 before. This correction affects all samples.
    • A programming error included unmarried partners of the head in the primary family (FAMUNIT = 1). This particular correction affects only the 1995-2008 samples, since the unmarried partner relationship category is available only in these years.
    • The original 1963 CPS data include some nonsense codes for total family income (FTOTVAL). This variable is no longer available for 1963 from IPUMS-CPS.
    • Where the original CPS data has both the head and the head's spouse as the same SEX, the IPUMS imposes an edit that codes the head as male and the spouse as female. The correction allows this edit to be carried out for one household in the 1973 CPS where it did not occur before.

February 23, 2009

    New data.

    • Posted new versions for 1962-1967. The only variables affected were OCC, IND, OCCLY, and INDLY. Persons not in the universe previously had values of either 0, 98, 99, or 999. All persons not in the universe now have a value of 99 in all of these variables.

November 9, 2008

    New data.

    • Posted new versions for 1963-2008 to include the original CPS variable FTOTVAL and make improvements to the OCCLY variable for 2003-2008.

September 16, 2008

    New data.

    New data soon.

    • All variables for the 2008 CPS are the same as those available in the 2007 CPS, except for the non-cash benefits and after-tax variables mentioned above, which are again being withheld for several months. These will be released in the IPUMS-CPS shortly after the Census Bureau releases them, most likely in early 2009.

November 12, 2007

    New data.

    • Released a new data extract system with the Attach Variables feature. This allows researchers to create variables specifying the characteristics of respondents' spouses, mothers, fathers, and household heads. New online help for the Case Selection and Attach Variables features is also available via hyperlinks from the data extract system. In addition, we have improved the look and functionality of our variable descriptions and codes pages.

October 24, 2007

    New data.

    • In April 2007, the Census Bureau released a new 2005 data file, with revisions to the health insurance variables. The Census Bureau documents this in a User Note. The new data are part of the current IPUMS-CPS release.
    • In the initial 2006 CPS release, several variables were withheld until the release of official reports on alternative income and poverty measures. These variables have since been released by the Census Bureau and are included in the current IPUMS-CPS release. Newly-released household variables are STAMPVAL,  HOUSRET, and PROPTAX. Person variables are ADJGINC, CAPGAIN,  CAPLOSS ,DEPSTAT , EITCRED,  EMCONTRB,  FEDRETIR, FEDTAX,  FEDTAXAC, FICA,  FILESTAT, MARGTAX,  PMVCAID, PMVCARE,  STATETAX, STATAXAC, and TAXINC.

    Edited variables.

    • The most significant changes are to the following employment-based insurance variables:GRPWHO1  and GROUPDEP (renamed to GRPDEPLY) (1.3% of cases modified); and GROUPTYP(renamed to GRPTYPLY) (.9% of cases modified).    Another group of health insurance variables (PHINSUR
    • In addition, the latest release of the 2006 CPS includes revisions to the health insurance variables (see the Census Bureau's User Note). The largest changes are to the following employment-based insurance variables: GRPWHO1 and GROUPDEP (renamed to GRPDEPLY)  (1.3% of cases modified); and GROUPTYP(renamed to GRPTYPLY) (1% of cases modified). Another group of health insurance variables (PHINSUR,  PHIOWN,  VERIFY,  COVERGH, and COVERPI) had approximately .7% of their values changed. The rest of the changes to the health insurance variables in 2006 amount to less than .5% of cases modified, except for PAIDGH, GROUPOUT (renamed to GRPOUTLY),  CHAMPVA (renamed to CHAMPVALY), and MOCAID, which were not changed at all.
    • The Census Bureau also modified the following variables (the percent of cases changed to the 'Not applicable' category appears in parentheses after each variable name): UNION (3.7%), EARNWEEK (3.7%), and HOURWAGE (35.3%). Additional information on these changes will appear in a future revision note.

    Survey changes.

    • For the 2007 March CPS, the Census Bureau dropped the Hurricane Katrina questions from the survey (IPUMS-CPS variables KATEVAC, KATEVAC2, and KATPRIOR) as well as the variable indicating country of previous residence (COUNTRY). All other variables for the 2007 CPS are the same as those available in the 2006 CPS, except for the non-cash benefits and after-tax variables mentioned above, which are again being withheld for several months. These will be released in the IPUMS-CPS shortly after the Census Bureau releases them.

May 1, 2007

    New data.

    • Posted new version of the 1994 sample: a correction was made to the MBPL variable.

February 2, 2007

    New data.

    • Posted new versions of the 2005 and 2006 samples.

    Edited variables.

    • A correction was made to the CUTOFF variable.

December 1, 2006

    New data.

    • Posted new data for 1963, 1966, and 1967. All weighting variables in these samples were adjusted by a constant. The samples now produce accurate population estimates. More information is available on the sample notes page.

October 19, 2006

    Expanded variables.

    Added variables.

    • The Census Bureau released alternative weight variables, which have been included for the 2004 ASEC in IPUMS-CPS as HHWT04 and PERWT04 (see our CPS Weights note for more information).
    • For the 2006 March CPS, several migration questions were added to the survey in order to assess the impact of Hurricane Katrina. The new IPUMS-CPS Katrina variables are KATEVAC, KATEVAC2, and KATPRIOR. In addition, several new veteran variable were introduced. These variables expand the information collected on a veteran's period(s) of service. For more information, see the variable descriptions for the new veteran variables: VET1,  VET2,  VET3,  VET4.

    New data.

    • In August 2006, the Census Bureau released a new 2005 ASEC file. The new dataset includes all variables listed above, plus FEDTAXAC and STATAXAC. In addition, changes were made to the weight variables and several health insurance variables. The Census Bureau documents this along with their March CPS downloads  (Endnote 16). The IPUMS-CPS variables affected by these changes are HWTSUPP(formerly HHWT. This variable was renamed. Please see this renaming scheme for more information.), WTSUPP (formerly PERWT), PAIDGH,  HIMCAID,  HIMCARE,  HICHAMP, PHINSUR,  PHIOWN,  CAID (renamed to CAIDLY),  CHAMPUS (renamed to TRCCOVLY),  CHAMPVA (renamed to CHAMPVALY),  MILITVA,  GROUPOWN (renamed to GRPOWNLY),  GROUPDEP (renamed to GRPDEPLY), PRIVOWN (renamed to DPOWNLY), PRIVDEP (renamed to DPDEPLY),  GROUPTYP (renamed to GRPTYPLY),  PRIVTYP (renamed to DPTYPLY),  GRPWHO1,  GRPWHO2,  PRIVWHO1 (renamed to DPWHO1),  PRIVWHO2 (renamed to DPWHO2), SCHIP (renamed to SCHIPLY),  VERIFY, GROUPOUT (renamed to GRPOUTLY),  PRIVOUT (renamed to DPOUTLY),  OUT,  COVERGH,  COVERPI,  KIDPRIV, and  KIDCAID. The weight variables were recalculated for the entire sample. For PRIVTYP (renamed to DPTYPLY), about 25% of people who were coded 'Family plan' or 'Self only covered' in the previous version of the dataset are coded 'NIU' in the new data. Aside from the weights and PRIVTYP, the changes to any given variable affect less than 1 percent of person records in the 2005 CPS.
