there are brand names (Lexus, Armani, Bacardi, Timber- land) and what might be called aspirational names. The California data show eight Harvards born during the 1990s (all of them black), fifteen Yales (all white), and eighteen Princetons (all black). There were no Doctors but three Lawyers (all black), nine Judges (eight of them white), three Senators (all white), and two Presidents (both black). Then there are the invented names. Roland G. Fryer Jr., while discussing his names research on a radio show, took a call from a black woman who was upset with the name just given to her baby niece. It was pronounced shuh-TEED but was in fact spelled "Shithead." Or consider the twin boys OrangeJello and LemonJello, also black, whose parents further dignified their choice by instituting the pro- nunciations a-RON-zhello and le-MON-zhello. OrangeJello, LemonJello, and Shithead have yet to catch on among the masses, but other names do. How does a name migrate through the population, and why? Is it purely a matter of zeitgeist, or is there some sensible explanation? We all know that names rise and fall and rise-witness the return of Sophie and Max from near extinc- tion-but is there a discernible pattern to these movements? The answer lies in the California data, and the answer is yes. Among the most interesting revelations in the data is the correla- tion between a babys name and the parents socioeconomic status. Consider the most common female names found in middle-income white households versus low-income white households. (These and other lists to follow include data from the 1990s alone, to ensure a large sample that is also current.)       Most Common Middle-Income White Girl Names   1. Sarah 3. Jessica
