2000-2004 Status Flags

A number of the status variables share a common set of flags describing the state of these variables. These flags are grouped here.

Status Flags
2004-2002 2000
A - Analyst adjusted a reported value
C - Analyst corrected a cell that was blank
H - Data suppressed
I - Imputation for a cell that previously was a nonresponse, using a method other than prior year
N - Original data field was blank
P - Imputation for a cell that previously was a nonreponse, using prior year data
R - Original data value was reported
S - Not applicable, not imputed
T - Total replaced with sum of detail during imputation
Z - Implied reported zero value
A - Analyst adjusted a reported value
C - Analyst corrected a cell that was blank
I - Imputation for a cell that was previously a nonresponse, using a method other than prior year
N - Original data field was blank
P - Imputation for cell that was previously nonresponse, using prior year data as base for imputation
R - Original data value was reported
T - Total adjusted to equal the sum of detail
Z - Implied reported zero value

As noted elsewhere, for purposes of removing imputed values from variables at reporting institutions, if the status flag = A, C, I, P, or T, the imputed value is set to a blank for any of these three years.
