ABSTRACT
Although South Asians have migrated around the globe for centuries and in substantial numbers since the mid-nineteenth century, it is only within the last two decades that a number of extended studies have emerged, not simply of the history of that migration, but rather of those communities for their own inherent interest and importance. Chart I Parsis of Indian origin formed the majority in all communities studied with the exception of Karachi where, naturally, most respondents had been born in Pakistan, and California where there was a substantial Iranian Zoroastrian population. The long-established centres of Hong Kong, Karachi and London have a higher proportion of members in the 16-25 age range than some of the newer American and Canadian centres because they have more older families whose children have grown up. The variations in the marriage patterns between the communities are interesting. Those with the highest proportion of single people were London and Karachi.
