ABSTRACT
The phase of the depression experienced in the coal industry has been accompanied by an abnormally large mass of unemployment in the coalfields. The accompanying table represents an attempt to estimate, from the birth-place statistics of the censuses, the extent of migration from other counties into Glamorgan during each decade. In 1901 the number of husbands not enumerated on the same schedules as their wives was 10,434 in Glamorganshire. The amount of migration in 1861-1871 was quite moderate compared with later decades, even though the gross estimate of 21,000 may err on the low side. An advance in the average agricultural wage- rate of a county in a given period may be, on the one hand, a cause of a relatively low volume of migration outward, or, on the other hand, an effect of a scarcity of labour consequent upon a relatively large volume of migration.
