COMPWT is a 14-digit numeric variable with four implied decimals. That is, 12345678901234 should be interpreted as 1234567890.1234. The IPUMS command files automatically make the necessary adjustment, so no further adjustment is needed.
COMPWT is the weighted average of two estimates. The first estimate is the two-stage ratio estimate that includes all the estimation steps given above. The second estimate consists of the composite estimate for the preceding month to which has been added an estimate of the change from the preceding month, based on that part of the sample which is common to the two months.
COMPWT increases reliability of estimates of month-to-month change and should be used to replicate published BLS labor force estimates. WTFINL is the final person-level weight and is the appropriate weight for most analyses of basic monthly data. For further information on composite estimates, see BLS's weighting overview and the technical documentation.
