Abstract

Upper-class people have long described near-total turnover from “old” to “new” money during major socioeconomic shifts, but quantitative measures of elite persistence often contradict their claims. Oil boom Dallas is one such case. Midcentury Dallas socialites consistently alleged that “new money” oil families replaced “old money” cotton families during the 1930s oil boom, but a dataset of the full upper class (n = 12,353) and most wealthy oilmen (n = 325) demonstrates that cotton families generally remained upper class, oilmen were mostly born upper class, and most upper-class people had both cotton men and oilmen somewhere in their family networks. What explains the disparity between upper-class perceptions and demographic reality? I argue that upper-class social worlds are often perceived and narrativized in terms of “prototypical elites,” who are especially wealthy and tied to regionally specific industries. Elite perceptions of total turnover reflect real churn among prototypical tycoons rather than churn among the upper class as a whole. Approaches to the study of elites and inequality that focus on ultra-rich individuals divorced from their relational contexts similarly overemphasize change and underemphasize persistence.

Figure 2. Cotton men and oilmen in the Dallas upper class.Note: Data in this figure come from the Dallas social registers published between 1925–1942. In total, 1,927 adult men were listed in those years, including 232 oilmen and 75 cotton men.

Figure 3. Industries of upper-class adult men, 1925–1942.Note: Data in this figure come from the Dallas social registers published between 1925–1942. “Other” includes any industry in the data with fewer than 35 upper-class men total in those years: advertising, agriculture, arts, cattle, communications, education, entertainment, government, groceries, hospitality, media, military, mining, pharmacy, religion, services, transportation, and utilities. In total, 1,927 adult men were listed in that time.

Figure 4. Upper-class persistence after 1940, by industry.–Note: These data cover men born before 1900 who were listed in the Dallas social registers between 1925–1929 (n = 929). Industries depicted here include any industry with more than 10 such men listed in those years. Persistence is calculated as whether the man or any of his children, nieces, nephews, or their lineal descendants were listed in any Dallas social register after 1940.

Figure 5. Share of upper-class men born into Dallas upper class, by industry.Note: These data cover adult men listed in the Dallas social registers between 1925–1942 (n = 1,927). Industries depicted here include any industry with more than 25 men listed in those years. I count them as born to the Dallas upper class if they have any parents, aunts, uncles, or grandparents listed in the Dallas social registers.

Figure 7. Class backgrounds of Dallas Petroleum Club oilmen, compared to upper-class cotton men and oilmen.Note: These graphs cover all cotton men and oilmen listed in the social registers between 1925–1942, compared to all members of the Dallas Petroleum Club from its founding in 1934 until 1942.

Figure 8. Oilmen were included in the upper class at especially high rates in 1940.Note: The number of oilmen and the size of the populations for Dallas, University Park, and Highland Park come from the 1940 US Census. University Park and Highland Park are wealthy incorporated towns in the center of Dallas housing much of the upper class; Highland Park is richer than University Park. The number of oilmen and the size of the population for the 1940 upper class comes from the 1940 edition of the social register.

Figure 9. Average kin distance from oilmen, cotton men, and select other industries in the Dallas upper class over time.Note: For this graph, I constructed the kinship network as it was for each year, based on birth, death, and marriage years. Then, for each person listed in that year’s social register, I calculated their minimum kin distance from an adult man in each industry. One kin tie, here, is equal to a spouse, sibling, parent, child, adult, uncle, niece, nephew, grandparent, grandchild, or first cousin. I have included only a sample of industries, selected for substantive interest and visual clarity.

Figure 10. Turnover from cotton to oil among Dallas upper-class homeowners.Note: These calculations are based on the home values in the manuscript 1930 and 1940 US Census. I have collected home values for all homeowners listed in the social registers from 1925–1942. Their homes were much more valuable than homes in the city overall. The median 1930 upper-class home value was $15k, compared to $4,932 across the city; in 1940, it was $10k, compared to $2,995 across the city. Across the entire county, the dataset covers most of the most expensive homes: 721 of the 792 homes in the top home value bracket listed in the aggregate Census in 1930 and 412 of the 478 homes in the top home value bracket in the entire county in 1940 ($20,000+ in both years). The five most prestigious mansions in 1930, based on home values and extensive qualitative research, were 4700 Preston (cotton to oil), 4800 Preston (no change-car dealer), 4500 Preston (no change-cotton), 4301 Lakeside (cattle to oil), and 2821 Turtle Creek (cotton to oil).
