LNKFW1YWT 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.
LNKFW1YWT is 0 for individuals that do not appear in all the required months. In addition, LNKFW1YWT is 0 for observations not in universe.
Description
LNKFW1YWT is a longitudinal weight for linking the same month across adjacent years of the CPS.
LNKFW1YWT is not available in samples that cannot be linked to the next year using CPSIDP. See here for details on these samples.
Researchers interested in replicating published BLS labor force estimates should use COMPWT. When analyzing ASEC data, researchers should use the person weight ASECWT. For analyses including the variables EARNWEEK, HOURWAGE, PAIDHOUR, and UNION, researchers should use the EARNWT variable.
Universe
- Those individuals who are eligible to link to the next year.
