Note: This is my homepage, which I maintain myself. The information here is the most up-to-date. The sociology department website also has a profile of me, but the information there is not the most current.

Research Interests:
       I am a social demographer who studies race, ethnicity, and family structure, the family's effect on children, and the history of the family. I am interested in mate selection as a social as well as a personal process. See the description of my book, The Age of Independence, below.

       I am currently working on:
* How Couples Meet and Stay Together, a longitudinal study of social life in the US, funded by the National Science Foundation. The first wave of the study was fielded in 2009. Public data, documentation, and further information is available at the Stanford Library's data distribution website. Links to news coverage about the "How Couples Meet" study is below, under prior media coverage. My first paper from this project, "Searching for a Mate: The Rise of the Internet as a Social Intermediary" was published in the August 2012 issue of the American Sociological Review. The How Couples Meet and Stay Together project has revolutionized our understanding of such topics as how couples meet, the role of technology and the role of family in personal relations, why couples stay together, and whether same-sex married couples stay together as long as heterosexual married couples do.

Selected Scholarly Publications (PDF format):

o M. J. Rosenfeld. 2007. THE AGE OF INDEPENDENCE: Interracial Unions, Same-Sex Unions and the Changing American Family. Harvard University Press. Available (in paperback) now from Amazon.com. You can also find the book, along with a selection from the text and the index, at the Harvard University Press website.

     The Age of Independence is a book which offers a new theory of family trends and social change in the US. The argument revolves around the independent life stage, a life stage which has emerged since 1960. Young adults experience the independent life stage after they have left their parents' homes, but before they have settled down to start their own family. During the independent life stage young men and women go away to college, travel, begin careers, and enjoy a period of relative social independence.
     The rise of the independent life stage has reduced parental control over the dating and mate selection choices of their children. The decline of parental supervision and control results in a sharp rise in interracial and same-sex unions, the kind of unions that previous generations of parents were able to prevent. Although most Americans and many scholars believe that young adults are returning home to the parental nest in ever greater numbers (a phenomenon the press has dubbed 'the boomerang effect'), this widely held perception has it exactly backwards. In fact what really distinguishes modern family life from previous eras is the new independence (geographic, residential, and social) of young adults from their families of origin.

     Until very recently, individual level census data from the past had never been available for scholarly analysis. What we knew about family life in the past came from diaries, from the official records of a few towns and churches, or from travel writers such as Tocqueville. Now that we have individual level census records from 1850 through 2000, we are able to look into long term trends in family life in a way that inevitably must cast some of our previous assumptions aside. I use the newly available census data to describe the rise of the independent life stage, and the sharp increase in the number of interracial and same-sex unions in recent years. My analysis of census data offers a new explanation for why the tumult of the industrial revolution failed to produce an increase in nontraditional unions: most families in the industrial revolution moved to cities and factory towns together, so the basic structure of parental supervision over young adults was maintained.
     By placing the post-1960 family changes in a long term historical and demographic context, I am able to offer a new perspective on the dramatic recent diversification in American family forms. I use in-depth interviews to explore the life histories of families and couples, and to illustrate the role that the independent life stage plays in social change.
     Same-sex marriage is one of the most divisive issues of our times. My book attempts to answer several questions related to same-sex marriage. First, why now? Why has the climate for gay rights in the U.S. changed so much in the past few years? Second, what next? What do the historical precedents and current demographic trends portend for the future of same-sex marriage in the US?
     The independent life stage has implications beyond the rise of nontraditional unions, which after all are still a small minority of all couples in the US. Because parents raise their children with their future independence in mind, parents raise their children differently, and these differences affect how we all think about individual freedoms.

 Related Figures and Data:
      * A figure and worksheet describing the increasing percentage of American couples that are interracial, by several definitions of interracial.
      * A figure and worksheet describing the increasing number of interracial and same-sex couples in the US.
      * A figure and worksheet describing the decreasing support in the US for laws against interracial marriage.
      * Figures on the phantom boomerang, describing the rise of independent living which is the opposite of the boomerang theory that is so widely believed. Now updated with new figures 4 and 5 showing the rise of solo living among men and women of all ages (but especially senior women).

See also the supplementary table (summarizing prior small-sample studies of children raised by same-sex couples) which is supposed to be available on Demography's website as well..
      * Because this paper was at the time of its publication, the only paper in the literature which compared children raised by same-sex couples to children raised by other types of families, using large sample nationally representative data, this paper's results were discussed in depth during the hearing phase of Perry v. Schwarzenegger, Federal district court 2010 (the case which puts the constitutionality of the anti-gay-marriage Proposition 8 on trial). See link to transcript of day 5 of the trial here. The judge ultimately struck down Proposition 8, and after appeals, the Federal district court opinion was upheld by the Supreme Court, and same-sex marriage became legal in California once again.
      * My paper on children raised by nontraditional families was subject to a comment in Demography (June, 2013) by Allen et al. My response (also in Demography, June, 2013) "Reply to Allen et al," Demography 50 (3) 963-969, is linked here, or here.
      * The debate over how to interpret the 2000 census data with regards to progress of children raised by same-sex couples was renewed in the DeBoer v. Snyder Michigan (2014) same-sex marriage trial, where I appeared as a witness for the plaintiffs, and Allen and Price appeared as witnesses for the state defendants. Judge Friedman's Michigan decision is here. The Michign decision largely settled the issue of social science, children, and same-sex marriage for the courts. The DeBoer v. Snyder decision was overturned on constitutional grounds by the 6th Circuit. The Supreme Court's 2015 Obergefell decision reversed the 6th circuit and affirmed the DeBoer trial decision, making same-sex marriage legal in all 50 states. More background documents from the DeBoer trial, including all expert affidavits, are here.

o M. J. Rosenfeld, 2010. "Still Weak Support for Status-Caste Exchange: A Reply to Critics" American Journal of Sociology Vol 115 Number 4, Pages 1264-1276. This paper is response to articles by Gullickson and Fu, and by Kallmijn, in the same issue of the AJS. The debate centers around my 2005 AJS piece on status-caste exchange, linked below.
o M. J. Rosenfeld, 2008. "Racial, Educational, and Religious Endogamy in Comparative Historical Perspective", Social Forces volume 87, issue 1, pages 1-32 (lead article). Links to typeset version (electronic access necessary) at JSTOR. See also a technical appendix with additional analyses and tables and figures showing that the trend in educational endogamy in the US is relatively flat over time, and that different measures of educational endogamy yield divergent answers as to whether educational endogamy is slightly increasing or slightly decreasing over time in the US. The divergent trend directions depending on the specification of the measure of educational endogamy is a sign that the popular theory that holds that educational endogamy is increasing in the US rests on a shaky empirical foundation.

The variables and their descriptions are best located at the website www.ipums.org, where the data come from. You will find that ipums is easy to navigate and has lots of relevant information. You can register for free and create your own dataset. For class purposes, I will be using
* ipums variable descriptions for CPS
* and ipums introduction to the CPS methodology

-----------------------------

*New, 2013 Stata class logs

* class 1 log, on tabulate and summarize.
* class 2 log, on generating new variables, on variable lables, and a bit on summarize, table, and t-test.
* class 3 log, revisiting some HW1 related Stata tools.
* class 4 log, t-test and t-distribution.
* class 5 log, dummy variables, weights, regression, and changes of scale.
* class 6, no log
* class 7 log, on regression with dummy variables and changing the comparison category
* class 10 log, graphing anscombe's data, with fits and residuals, also how to make the Vietnam vet dummy variable.
* class 12 log, on residuals, graphing, and dfbetas.
-------------------------------------

Supplementary information:
* In case you need it, but you probably won't, A multiyear CPS dataset, in zipped format (37MB Zipped, 95MB when expanded, Stata 10 version). Here is a link to the ipums codebook for the CPS data extraction I used (the 2000 data is just a subset of this multiyear extraction).

My notes on how to match husband to wife or householder to partner, to create couples data, using STATA and census data from ipums.

Two graphs to get you thinking about life course versus historical and cohort effects, from the 2000 CPS. Mean income by age and gender, and mean education by age and gender. A log for the creation of the graphs is here. Figures for health status by age are here, embedded with commands and notes.

Some additional reading that we may or may not get to:

* On the subject of what to do when sampling fraction is 1 (see here for a definition of sampling fraction), see blog posts by Statistician Andrew Gelman here and here, and see this paper by Desbiens.

* "The Earth is Round" by Jacob Cohen, on Null Hypothesis testing and Bayesian inference


* Lisse et al's 2003 paper from the Annals of Internal Medicine on the hazards of Vioxx (Rofecoxib), for a discussion of the dangers that can befall us when we don't take the power of tests into account.

* On the subject of data presentation with maps, see these area-weighted cartographs of election results. On the subject of Tufte and data presentation, see Peter Norvig's parody of Powerpoint using the Gettysburg Address.
