Called patronymic surnames, these last names, as a group, are second to place-name-based last names in popularity, making up about 32 percent of last names in the United States.

The surnames of these North Kanataka based, Kannada speaking Deshastha Brahmins, can be identical to those of Maharashtrian Deshastha Brahmins, for example, they have last names like Kulkarni, Deshpande and Joshi.

These surname lists can be used to identify cohorts of people with South Asian and Chinese origins from secondary data sources with a high degree of accuracy.

The same members of the research team reviewed these surname listings and eliminated names that were not typically Chinese, South Asian or Iranian, or which were common to other population groups.
In conclusion, these surname lists can be used to accurately identify cohorts of people with South Asian and Chinese origins from secondary data sources, although these cohorts would, by necessity, not always be comprehensive or representative of the entire South Asian or Chinese population.
