During the past two decades, there has been an outpouring of research on the seaboard mortality associated with intercontinental migration during the seventeenth, eighteenth, and nineteenth centuries. The focus of historical interest in this linkage between mortality and migration has been the Atlantic slave trade. We now have mortality rates on voyages from various regions in Africa to various destinations in the Americas, from the late seventeenth century to the mid-nineteenth century (see Curtin, 1968, 1969: 275-286; Klein and Engerman, 1976, 1979; Klein, 1978; Postma, 1979; Miller, 1981; Cohn and Jensen, 1982a, 1982b; Cohn, 1985; Eltis, 1984, 1987; Steckel and Jensen, 1986; Galenson, 1986). These slave studies have spawned renewed interest in the mortality associated with other seaborne populations, and mortality rates have been calculated on Dutch immigrant voyages to the East Indies during the eighteenth century, European convict and immigrant voyages to North America and European immigrant voyages to Australia during the eighteenth and nineteenth centuries, and Indian and Pacific Islander indentured labor voyages to Fiji and Queensland, Australia, during the late nineteenth and early twentieth centuries (see Riley, 1981; Eltis, 1983; Cohn, 1984, 1985, 1987, 1988; Grubb, 1987; Ekirch, 1987; Morgan, 1985; Shlomowitz, 1986, 1987, 1989; McDonald and Shlomowitz, 1988, forthcoming).
