I am an Assistant Professor in the Population Studies and History of Medicine programs at the University of Minnesota. From 2007-10 I was a Lecturer (equivalent to an Assistant Professor) in the History Programme at Victoria University of Wellington.

Thanks for coming to find out a little more about me. You may be procrastinating, but that's OK. Structured procrastination is an effective way to spend your time.

If you're looking for copies of papers I've presented or published, you can find them immediately to the right, along with a copy of my cv.

My research interests are in the demographic, social, and economic history of Australasia and North America in the 19th and 20th centuries. My research is on the United States and New Zealand, but I try to read in Canadian and Australian scholarship for its connections and comparisons with what I study. My current research projects are about (1) health and living standards in New Zealand and the United States from the early nineteenth century to the present, and (2) married women's work and the family economy in the United States between the Civil War and World War II.

My research explores how the impact of early life influences on later life outcomes has changed over time. This focus on changes in the life course brings a conceptual unity to studies of weight and mortality in New Zealand soldiers, migration and later-life health in Iowa women, children in early-twentieth century Saint Paul, and married couples in Chicago, to name just a few of the data sources I have worked with. My work is characterized by a search for early-life data that can be linked to later life sources. The practical challenges of this work have taken me into work on record linkage and efficient ways to crowd-source or computer recognize old hand writing. My work is also marked by a mid-Pacific blending of different versions of the English language. Should that be an "ess" or a "zed" or even a "zee"? It could be either. Use both, and let the copy editor sort it out

The New Zealand research is jointly with Kris Inwood (Guelph) and Les Oxley (Waikato). We are using anthropometric methods to create consistent measures of Maori (indigenous) and Pakeha (European descended) living standards. This work has been funded by the Health Research Council and Marsden Fund (equivalent of NIH and NSF for American readers).

My research on married women's work is a continuation of work I began in graduate school. I am currently digitizing state labor bureau surveys that are not available in the Historical Labor Statistics Project series. Please get in touch if you are interested in using data from this research, as I am happy to share data that has been entered.

For a decade from 2001 I co-ordinated the North Atlantic Population Project (NAPP) at the Minnesota Population Center. NAPP is an international collaboration co-ordinated by the MPC to harmonize and distribute historical (19th and 20th century) census data for social science and historical research. I am particularly interested (and have a lot of experience) in classifying occupations in historical census data. I coded hundreds of thousands of occupations in the IPUMS-USA census samples and the 1880 U.S. census complete-count dataset.

I did my PhD in history at the University of Minnesota. My dissertation looked at married women's labor force participation in the United States between 1860 and 1940. The main data sources I used were census samples from the IPUMS and the 1880 complete count census in the North Atlantic Population Project, as well as survey data from the 1888-90, 1917-19 and 1935-36 Cost of Living surveys and surveys of consumer expenditures. I also worked extensively with interviews of workers from the Hawthorne works of the Western Electric company for insight on public opinion about married women's work in the 1920s and 1930s. Please contact me if you are interested in reading any of this work.

Before going to the University of Minnesota on a Fulbright scholarship, I did a BA(Hons) degree in Economics and History, and a BSc (BS for American readers) in Mathematics and Statistics at Victoria University of Wellington.

I wrote my Honours thesis/research essay on the history of New Zealand department store employees -- publications from this work are listed in my CV to the right.

Besides my academic pursuits I do a lot of long-distance running -- if you really are procrastinating you can find my New Zealand running results at Wellington Scottish or Minnesota results on the extremely useful Raceberry Jam. I also listen to Bob Dylan, but would like to assure you I did not move to Minnesota for this reason. To my shame I have not yet made the pilgrimage to Hibbing.

Health and living standards in New Zealand and the US

Please contact me if you are interested in discussing currently unpublished research.

We are currently expanding our dataset of World War I soldiers by crowd-sourcing the transcription of all New Zealand's World War I personnel files. This project, Measuring the ANZACs is a collaboration of the Minnesota Population Center, The Zooniverse, Archives New Zealand with additional organizational support from Auckland Museum. We launched in October 2015 and have the goal of a complete transcription of all 140,000 records! Please get involved in the project! We are very happy to support educational use of the site. Please contact me to discuss lesson plans, guest lectures to classes, and talks to groups in the community.

Long-term effects of Local Area New Deal Work Relief in Childhood on Educational, Economic and Health Outcomes over the Life Course: Evidence from the Wisconsin Longitudinal Study. Demography, 2022. (With Sepideh Modrek, David Rehkopf, and John Robert Warren).
Casual abstract: New Deal relief was good for kids in the long term, seeming to mitigate some of the effects of living in an area with high unemployment.

Life-course transitions in rural residence and old-age mortality in Iowa, 1930-2014. RSF: Russell Sage Foundation Journal of the Social Sciences, 2022. (With Wendy Rahn and DeAnn Lazovich).
Casual abstract: Growing up in a small town, or moving to one in later life was associated with earlier mortality, compared to farm or city women. Social class differences in rural life chances and opportunities are a likely part of this story.

Childhood Growth and Socioeconomic Outcomes in Early Adulthood: Evidence from the Inter-war United States. History of the Family, 2022. (With Jonas Helgertz and John Robert Warren ).
Casual abstract: Being a little heavier in childhood was associated with better early adult outcomes, in an era when malnutrition was still common in American childhood

Weight Gain is Associated with Shorter Life Span: A Longitudinal Study of Soldiers Serving in both World Wars. Journal of Biosocial Science, 2022. (With Monica Miecznikowski).
Casual abstract: Putting on more weight was associated with a shorter life span (1 additional kg/m2 associated with 0.7 years shorter life. See the Twitter summary)

The influence of kin proximity on the reproductive success of American couples, 1900-1910. Demography, 2021. (With J. David Hacker, Jonas Helgertz and Matthew A. Nelson).
Casual abstract: Living near your parents is associated with having slightly more kids, but ... this is something that needs more research!

The Effects of Education on Mortality: Evidence from Linked U.S. Census and Administrative Mortality Data. Demography, 2020. (With Andrew Halpern-Manners, Jonas Helgertz, and John Robert Warren).
Casual abstract: More schooling has a fairly robust causal (not casual) relationship with living longer. A year of school = about 0.4 years longer life.

Urban vs rural residency and allergy prevalence among adult women. Annals of Allergy, Asthma, and Immunology, 2018. (With Nita Patel, Anna Prizment, Bharat Thyagarajan, Heather Nelson, DeAnn Lazovich, and Timothy Church).

Family structure and childhood anthropometry in Saint Paul, Minnesota in 1918, History of the Family, 2017. (PMC link)
Casual abstract: Most of the pre-school children in Saint Paul were below average (modern averages, to be clear). But children from richer families and families with fewer children were not as short. Growth faltering was evident in a way similar to modern developing countries.

Household budget studies in the British dominions, 1873-1939. Historical Household Budgets Working Paper No. 2. Now available in Rivista di Storia Economica in August 2016.
Casual abstract: Household budget studies in Australia, Canada, New Zealand, and South Africa were conducted less frequently than in the U.S., U.K. or Scandinavia before WWII. The budget studies in the dominions are of comparable quality, and are an under-utilised resource for studying social and economic change in these countries.

Physical growth and ethnic inequality in New Zealand prisons, 1840-1975, History of the Family, 2015.
Casual abstract: Inequality in stature between Maori and Pakeha was at its greatest in the early twentieth century before narrowing rapidly, giving a new picture of ethnic inequality in twentieth century New Zealand.

Chapters on the early history of New Zealand family budget studies, and the history of the New Zealand consumer price index, in The New Zealand CPI at 100: History and Interpretation (buy the book, Christmas is coming)
Casual abstract: The New Zealand consumer price index weights were based on what seem like remarkably small surveys of consumers, but this wasn't out of line with experience in comparable countries. Working with a limited budget the New Zealand statistics department was innovative to try and obtain decent data.

Birth weight and adult health in historical perspective: Evidence from a New Zealand cohort, 1907-1922, Social Science & Medicine, Vol. 107, April 2014.
Casual abstract: Provides the earliest ever evidence on the fetal origins hypothesis in young adults, with birth weight having a slightly greater impact on adult health in the past. However, New Zealand babies in the early twentieth century were robust at birth weighing about the same as babies in the late 1990s.

Height, weight and mortality in the past: New evidence from a nineteenth century New Zealand cohort. Presented at 2011 Social Science History and 2013 Population Association and Cliometrics meetings (with Kris Inwood and Les Oxley).
Casual abstract: We provide new historical evidence on the mortality risk of being overweight in early adulthood. Our results suggest that the mortality risk of being overweight begins to rise sharply when people are moderately overweight.

Longitudinal studies of human growth and health: A review of recent historical research, November 2010. Journal of Economic Surveys (with Kris Inwood).
Abstract: This paper reviews recent literature using stature and weight as measures of human welfare with a particular interest in cliometric or historical research. We begin with an overview of anthropometric evidence of living standards and the new but fast growing field of anthropometric history. This literature is always implicitly and often explicitly longitudinal in nature. We then discuss (i) systematic empirical research into the relationship between conditions in early life and later life health and mortality and (ii) historical evidence on the relationship between body mass, morbidity and mortality. We conclude with a discussion of the importance of historical sources and understandings to health economics and population health.
