Finally, rural health researchers may be critical of our definition of rurality, which was solely based on population size (centers with less than 100,000 people), and our classification of migration patterns is reductive in that it did not divide urban migrators into those who migrated to other urban places and those who migrated from urban to rural places.

Future research on migration should use definition and classification of migration in the census as key criteria for identifying migrants.
In addition, reports use different classifications of migration, making it difficult for researchers and policymakers to gain a consistent picture, particularly regarding interprovincial migration.
Cells can migrate as single cells or as a group in clusters, sheets; this has led to the classification of cell migration into single-cell and collective cell migration.
Classification of VM migration mechanism is shown in Fig. 6 and it is based on the similarity of the migration strategy, used by the authors.
Classification of the existing migration mechanisms into three basic categories: type of live VM migration, duplication based VM migration and context aware migration based on the objectives and techniques used.
The distributions of new classification of diabetes by migration status are shown in Table 3.
We also examine whether fertility differs by duration of residence in Kinshasa, number of lifetime moves, age at first migration, urban/rural classification of birthplace, and the distinction between intra-Kinshasa migration and migration to Kinshasa.. Migrants have significantly higher fertility than permanent Kinshasa residents, but the difference is relatively small in magnitude.
Other factors which could have led to misleading study results include selection of study areas, ascertainment of cases, population selected for the denominator, migration, classification of exposure and blinding of investigators to the fluoridation status of cases.
Specifically, we investigate the association between fertility and (1) duration of residence in Kinshasa, (2) number of lifetime moves, (3) age at first migration, (4) urban/rural classification of birthplace, and (5) the distinction between intra-Kinshasa migration and migration to Kinshasa.
