                                 New Welfare Reform Fields

         The move from Oracle to MySQL has just been completed. This will enable the
addition of the new welfare reform fields to TRIM’s database tables. However, at this
time those fields are not yet available except via a supplementary file for the immigrant-
adjusted data, (CPSI2001Supplement, on Boreas only). You may view a list of the new
fields that will eventually be added to TRIM’s regular database tables by clicking here.

                          Record Counts and Weighted Totals

        Consistent with past trends, average weights on the March CPS are higher than
for the previous year. The following tabulation shows weighted and unweighted counts
on both immigrant-adjusted and unadjusted files for both the current and previous years.
Also shown are original pre-conversion record counts that include empty non-interview
households and child-only families that the TRIM conversion merges with primary
families or single household heads. There are 14,729 non-interview households. 386
child-only families in the immigrant-adjusted data and 306 in the unadjusted data were
merged with other TRIM families. The weighted sum of households in the immigrant-
adjusted data differs somewhat from the sum computed from unadjusted data due to a
methodological difference between the Census algorithm that identifies household weight
and the one used by the conversion code. That difference results in the use of different
weights for a few households. (Read explanation.)
