November 27, 2018

    Corrected data.

    • We have inserted a leading zero in the values of MEPSID and MEPSIDRD in the 1996-2004 samples to replace a leading blank that was preventing users from merging data using formatted data extracts to ASCII data extracts read in using a stats package syntax file. The merging issue previously observed has been resolved.

    New data.

    • The variable PERNUM is now included on round-level records to support hierarchical IPUMS extracts in R.

October 4, 2018

    Modified data.

    • Corrected duplicate cases for 1996 sample.

August 31, 2018

    New data.

    • IPUMS MEPS now includes 2016 FYC data; over 1,300 variables (both annual person-level variables and round-level variables) are now available through the extract system.

    Modified data.

    • To account for the release of pooled variance estimation variables (STRATAPLD and PSUPLD); the variable names for STRATAP and PSUP were updated to STRATANN and PSUANN to more clearly note that they are designed to produce annual estimates.
    • A missing data code for HPTOTNIGHT was updated for consistency with other IPUMS missing data codes; cases previously coded as -9 are now classified as "998: Not ascertained".
    • Missing and top-code values for WAGENEWRD were updated for consistency with other IPUMS missing data codes (they previously matched AHRQ missing and top-coded values and were not labeled in data extracts). Cases previously coded as -1.00 are now classified as "0.00: Not in Universe"; cases previously coded as -10.00 are now classified as the respective top-code for each year of data; cases previously coded as -13.00 are now classified as "99.91: Initial wage imputed"; and cases previously coded as -8.00 are now classified as "99.98: Not ascertained".
    • The variable WAGEHRRD was expanded by one column and its missing data and top-code values were updated for consistency with other IPUMS missing data codes (they previously matched AHRQ missing data codes and were not-labeled in extracts). Cases previously coded as -1.00 or -3.00 are now classified as "0.00: Not in Universe"; cases previously coded as -2.00 are now classified "9999.94: Determined in previous round"; cases coded as -10.00 are now classified as the respective top-code for each year; cases previously coded as -7.00 are now classified as "9999.97: Refused"; cases previously coded as -8.00 are now classified as "9999.99: Don't know"; and cases previously coded as -9.00 are now classified as "9999.98: Not ascertained".
    • The missing data codes for HOURWRKRD in 2001, 2004, and 2007-2009 reflected AHRQ-assigned values, and were not consistent with other IPUMS missing data codes. Cases previously coded as -1 or -3 are now classified as "996: Not in Universe"; cases previously coded as -2 are now classified "994: Determined in previous round"; cases previously coded as -7 are now classified as "997: Refused"; cases previously coded as -8 are now classified as "999: Don't know", and cases previously coded as -8 are now classified as "998: Not ascertained".
    • The code for "determined in previous round" was changed from 96 to 94 for the round-level variable WAGEHRSRCRD for greater comparability across variables. The variable is otherwise unchanged.

August 13, 2018

    New data.

    • Newly released 2015 MEPS data and 300+ additional variables, including round-level, are now integrated into the IPUMS MEPS database.

    Modified data.

    • EDUCATN has been renamed EDUCYR to match the original MEPS variable name and additional samples were added.

June 21, 2018

    Updated data.

    • IPUMS MEPS has updated USBORN and YRSINUS in 2013 to include both panels 17 and 18. Previously, panel 17 members had been classified as "inapplicable" because of a change in how MEPS offers these variables.

    Corrected data.

    • IPUMS MEPS has corrected an error affecting CPSFAMID. In previous versions of the data, CPSFAMID used incorrect original data for 2008 and 2012, causing the data to be missing in 2012 and incorrect in 2008.

February 5, 2018

    Corrected data.

    • IPUMS MEPS has corrected an error affecting PID and MEPSID. In previous versions of the data, all values of PID and the PID portion of MEPSID (DUID + PID + PANEL) were zero.

January 30, 2018

    New data.

    • Beta version of IPUMS MEPS released.
