Full Description
INITWGT contains the base survey weight for the sample unit to which the sample person
belongs. This base survey weight is the inverse of the probability of selection for
the sample unit, adjusted only for unit non-response and, in rare instances, for sampled
units that turned out to represent more than one separate residence. Unlike final
panel and calendar year weights, INITWGT includes no adjustment for attrition of households
from SIPP panels and are not adjusted at the person level to match any external controls.
SSB users can utilize the weights to produce estimates that account for idiosyncratic
probability of selection of sample units and for unit-nonresponse. Estimates for each
SIPP panel, using these weights, become representative of the U.S. non-instutionalized
population as of the beginning of the panel. For instance, using INITWGT, the distribution
of calendar year 2010 administrative earnings for sample persons in the SSB from the
1984 SIPP panel would be representative of the U.S. population as of calendar year
1984.
