Models for record types, record type relationships, and weights in IPUMS datasets.
Model the IPUMS datasets (sometimes called ‘samples’.) This module models the record types, weighting and record type relationship for IPUMS data, not the samples themselves.
Every dataset in a collection will have these same characteristics: It will be a collection of record types and each record type has some information about it and its relationships to the other record types. Every collection has a single hierarchy of record types. A record type on a particular data product may have a default weight variable – or it may not.
