For the 2018 SIPP, many asset variables are now imputed with statistical model-based imputation, as described in Section 6.2 of the SIPP Users’ Guide at <https://www2.census.gov/programs-surveys/sipp/tech-documentation/methodology/2018_SIPP_Users_Guide.pdf.> The asset variables now imputed with this technique are:

EOWN_CHK

EOWN_SAV

EOWN_CD

EOWN_MM

EOWN_ST

EOWN_MF

EOWN_GOVS

EOWN_IRAKEO

EOWN_THR401

EOWN_PENSION

EOWN_MCBD

EOWN_LIFE

EOWN_BSI

EOWN_RP

EOWN_RE

EOWN_ANNTR

EOWN_OINV

ETHR401VAL

EIRAKEOVAL

EDEBT_CC

EDEBT_ED

EDEBT_OT

EDEBT_MED

EMED_AMT

For the yes/no variables in this list with a prefix of EOWN or EDEBT, the status flag equals 4 for values imputed using model-based imputation.  For the continuous variables ETHR401VAL, EIRAKEOVAL, and EMED_AMT, some respondents did not provide an exact amount for their retirement account or medical debt balance, but did provide a response to the range follow-up question (e.g. said the balance of their 401(k) was between $25,000 and $50,000).  For these variables, the status flag equals 6 if the variable was imputed with model-based imputation using the range information.  If the respondent did not provide range follow-up information, the status flag equals 4.
