Abstract

A study was made of the factors that affected the casefinding of internal migrations in Liberia using the Chandrasekar—Deming dual enumeration and tabulation methods. The results of this work suggest that the recording and not recording of a migration is not a random occurrence but is associated with a particular enumeration system, origin and destination of the migration, and the migrant’s age, sex, and location of current residence.

Internal Migration, Enumeration System, Rural Location, Urban Location, Current Residence
