Your definition of a displaced worker (here: https://cps.ipums.org/cps-action/vari…) does not seem to conform to the BLS definition.
Displaced workers according to the IPUMS definition:
have lost their job in the last 3 years
their company or plant shutted down, their shift or position has been eliminated, or had insufficient work
are not self-employed
do not expect to be recalled in the next 6 months
Any feedback is welcome
