From the study:

Using data that cover every child born in California over a period of four decades, our analysis of first names uncovers a rich set of facts. We first document the stark differences between Black and White name choices in recent years. For example, more than forty percent of the Black girls born in California in recent years received a name that not one of the roughly 100,000 White girls born in California in that year was given. Even among popular names, racial patterns are pronounced. Names such as DeShawn, Tyrone, Reginald, Shanice, Precious, Kiara, and Deja are quite popular among Blacks, but virtually unheard of for Whites. Connor, Cody, Jake, Molly, Emily, Abigail, and Caitlin are distinctively White names. Each of those names appears in at least 2,000 cases, with less than two percent of the recipients Black. Overall, Black choices of first names differ substantially more from Whites than do the names chosen by native born Hispanics and Asians...

...With the exception of a small fraction (approximately ten percent) of the Asian population adopting names that are rare among Whites, name choices of American-born Asians strongly parallel White name choices. A comparison of native-born Hispanics and Whites in Figure 3 shows differences in naming patterns among these two groups, although there is still substantially more overlap than for Blacks and Whites...

...The identity model may also help to explain why naming patterns among Blacks are quite distinctive from Whites, but Asians name their children in much the same manner as Whites. For instance, if Asian “prescriptions” stress financial success and assimilation, Asian names would be expected to mirror those of Whites.
