Research
Song 's research extends the two-generation paradigm in sociological studies to three and more generations, examining the potential roles of parents, grandparents, great-grandparents, relatives in kin networks, and even more remote ancestors in influencing the status outcomes of their descendants. Her ongoing work uses historical and contemporary archival sources, family genealogies, longitudinal and retrospective surveys, inscriptions, oral histories, and linked administrative registers from various populations to illustrate the persistence of social inequality across generations, even in the face of dramatic demographic and institutional changes.

Abstract
Despite long-standing recognition of the importance of family background in shaping life outcomes, only recently have empirical studies in demography, stratification, and other areas begun to consider the influence of kin other than parents. These new studies reflect the increasing availability of genealogical microdata that provide information about ancestors and kin over three or more generations. These data sets, including family genealogies, linked vital registration records, population registers, longitudinal surveys, and other sources, are valuable resources for social research on family, population, and stratification in a multigenerational perspective. This article reviews relevant recent studies, introduces and presents examples of the most important sources of genealogical microdata, identifies key methodological issues in the construction and analysis of genealogical data, and suggests directions for future research.

Abstract
Despite the theoretical importance of intragenerational mobility and its connection to intergenerational mobility, no study since the 1970s has documented trends in intragenerational occupational mobility. The present article fills this intellectual gap by presenting evidence of an increasing trend in intragenerational mobility in the United States from 1969 to 2011. We decompose the trend using a nested occupational classification scheme that distinguishes between disaggregated micro-classes and progressively more aggregated meso-classes, macro-classes, and manual and nonmanual sectors. Log-linear analysis reveals that mobility increased across the occupational structure at nearly all levels of aggregation, especially after the early 1990s. Controlling for structural changes in occupational distributions modifies, but does not substantially alter, these findings. Trends are qualitatively similar for men and women. We connect increasing mobility to other macro-economic trends dating back to the 1970s, including changing labor force composition, technologies, employment relations, and industrial structures. We reassert the sociological significance of intragenerational mobility and discuss how increasing variability in occupational transitions within careers may counteract or mask trends in intergenerational mobility, across occupations and across more broadly construed social classes.

Song, Xi and Robert D. Mare. 2017. "Short-Term and Long-Term Educational Mobility of Families: A Two-Sex Approach.” Demography 54(1): 145-173.
Abstract
We use a multigenerational perspective to investigate how families reproduce and pass their educational advantages to succeeding generations. Unlike traditional mobility studies that have typically focused on one-sex influences from fathers to sons, we rely on a two-sex approach that accounts for interactions between males and females—the process in which males and females mate and have children with those of similar educational statuses and jointly determine the educational status attainment of their offspring. Using data from the Panel Study of Income Dynamics, we approach this issue from both a short-term and a long-term perspective. For the short term, grandparents’ educational attainments have a direct association with grandchildren’s education as well as an indirect association that is mediated by parents’ education and demographic behaviors. For the long term, initial educational advantages of families may benefit as many as three subsequent generations, but such advantages are later offset by the lower fertility of highly educated persons. Yet, all families eventually achieve the same educational distribution of descendants because of intermarriages between families of high- and low-education origin.

Abstract
In recent years, sociological research investigating grandparent effects in three-generation social mobility has proliferated, mostly focusing on the question of whether grandparents have a direct effect on their grandchildren’s social attainment. This study hypothesizes that prior research has overlooked family structure as an important factor that moderates grandparents’ direct effects. Capitalizing on a counterfactual causal framework and multigenerational data from the Panel Study of Income Dynamics, this study examines the direct effect of grandparents’ years of education on grandchildren’s years of educational attainment and heterogeneity in the effects associated with family structure. The results show that for both African Americans and whites, grandparent effects are the strongest for grandchildren who grew up in two-parent families, followed by those in single-parent families with divorced parents. The weakest effects were marked in single-parent families with unmarried parents. These findings suggest that the increasing diversity of family forms has led to diverging social mobility trajectories for families across generations.

Song, Xi and Robert D. Mare. 2015. "Retrospective Versus Prospective Approaches to the Study of Intergenerational Social Mobility." Sociological Methods and Research 44(4): 555-584.
Abstract
Most intergenerational social mobility studies are based upon retrospective data, in which samples of individuals report socioeconomic information about their parents, an approach that provides representative data for offspring but not the parental generation. When available, prospective data on intergenerational mobility, which are based on a sample of respondents who report on their progeny, have conceptual and practical advantages. Prospective data are especially useful for studying social mobility across more than two generations and for developing joint models of social mobility and demographic processes. Because prospective data remain relatively scarce, we propose a method that corrects retrospective mobility data for the unrepresentativeness of the parental generation and thus permits them to be used for models of social mobility and demographic processes. We illustrate this method using both simulated data and data from the Panel Study of Income Dynamics. In our examples, this method removes more than 95 percent of the bias in the retrospective data.
Song, Xi, Cameron D. Campbell, and James Z. Lee. 2015. "Ancestry Matters: Patrilineage Line Growth and Extinction." American Sociological Review 80(3): 574-602.
Abstract
Patrilineality, the organization of kinship, inheritance, and other key social processes based on patrilineal male descent, has been a salient feature of social organization in China and many other societies for centuries. Because patrilineage continuity or growth was the central focus of reproductive strategies in such societies, we introduce the number of patrilineal male descendants generations later as a stratification outcome. By reconstructing and analyzing 20,000 patrilineages in two prospective, multi-generational population databases from eighteenth- and nineteenth-century China, we show that patrilineages founded by high-status males had higher growth rates for the next 150 years. The elevated growth rate of these patrilineages was due more to their having a lower probability of extinction at each point in time than to surviving patrilineal male descendants having larger numbers of sons on average. As a result, male descendants of high-status males account for a disproportionately large share of the male population in later generations. In China and elsewhere, patrilineal kin network characteristics influence individuals’ life chances; effects of a male founder’s characteristics on patrilineage size many generations later thus represent an indirect channel of status transmission that has not been considered previously.

Song, Xi and Yu Xie. 2014. "Market Transition Revisited: Changing Regimes of Housing Inequality in China, 1988-2002." Sociological Science 1: 277-291.
Abstract
This paper revisits the market transition theory of Nee (1989), using housing as an alternative to income as a measure of socioeconomic attainment. We argue that housing space is a better outcome variable by which to evaluate Nee’s market transition theory because it is a more consistent measure of socioeconomic success than income before and after the economic reform. Using three waves of a national household survey in 1988, 1995, and 2002, we compare temporal changes in the role of market and redistributive determinants for income and housing space. In support of a weak form of the theory, our results show that market determinants replaced redistributive determinants over time as the most significant predictors of housing space. In contrast, parallel analyses of income show mixed results for market and redistributive determinants.

Wu, Xiaogang and Xi Song. 2014. "Ethnic Stratification in China's Economic Transition: Evidence from Xinjiang Uyghur Autonomous Region." Social Science Research 44(March): 158-172.
Abstract
This paper analyzes a sample from the 2005 mini-census of Xinjiang to examine ethnic stratification in China’s labor markets, with a special focus on how ethnic earnings inequality varies by employment sector. We show that Han and Uyghur Chinese dominated different economic sectors. Excluding those in agriculture, Uyghurs were more likely to work in government or institutions than either Han locals or migrants, and also more likely to become self-employed. The Han–Uyghur earnings gap was negligible within government/public institutions, but increased with the marketization of the employment sector. It was the largest among the self-employed, followed by employees in private enterprises and then employees in public enterprises. Han migrants in economic sectors enjoyed particular earnings advantages and hukou registration status had no impact on earnings attainment except in government/public institutions. These findings have important implications for understanding social and economic sources of increasing ethnic conflicts in Xinjiang in recent years.
