2021 marked the 30-year anniversary of the publication Fatal Years: Child Mortality in the late Nineteenth-Century United States, a pioneering work in historical demography by Samuel H. Preston and Michael R. Haines. This special issue showcases the current state of historical mortality studies through a collection of articles originally presented at two commemorative sessions at the 2021 meeting of the Social Science History Association. It provides new and more nuanced evidence on several of the major themes of Fatal Years in terms of the mortality experience and includes studies of a wide range of contexts, from North America, to Ireland, England and Wales, and continental Europe. They all bring new evidence and leverage the dramatic development that has taken place in availability of large-scale micro-level data in the 30 years since Fatal Years was published. This introduction first provides some background to the collection and then summarizes the main findings from the different articles included. Preston and Haines provide a coda to this collection with a short reflection article on researching and writing Fatal Years.

With only a few exceptions, the historical study of individual-level correlates of child mortality in the United States has been limited to the period surrounding the turn of the twentieth century, when children ever born and children surviving data collected by the 1900 and 1910 censuses allow indirect estimation of child mortality. The recent release of linked census data, such as the IPUMS MLP datasets, allows a different type of indirect estimation over a longer period. By following couples across subsequent decennial censuses, it is possible to infer child mortality by measuring whether couples’ own children in the first census were still present in the second census. We focus our analysis on children aged 1–3 in the first of two linked censuses, who were less likely to be undercounted by the census than infants, and unlikely to be living apart from their parents in the second census. We estimate child mortality over the intervening decade and use OLS regression to correlate that mortality to the residence location and socioeconomic characteristics of their parents’ households. We limit our analysis to three panel datasets for married couples linked between the 1850–60, 1860–70, and 1870–80 censuses, when real estate and personal estate wealth data were collected. Our results indicate a significant negative relationship between wealth and child mortality across all regions of the United States and over the entire period examined.

This article appraises kin availability and migration timing on French-Canadian child mortality in an early twentieth-century North American industrial city. The analysis is based on the exploitation of an original dataset constructed by linking the 1910 census data (IPUMS-Full Count) for Manchester, New Hampshire to Quebec Catholic marriage records (BALSAC) and geocoding census data at the household level (Sanborn Fire Insurance Maps). Our results suggest that the presence of maternal and paternal grandmothers in the city living in different households were associated with reduced child mortality and that French-Canadian women who arrived in the United States as children or young adults experienced higher child mortality compared to second-generation French Canadians and those who migrated at a later age.

This paper takes, as its starting point, Preston and Haines’ observation in Fatal Years that social class was the most important influence on infant and child mortality in England and Wales in the early twentieth century. A subsequent study suggested that this could in part be due to the spatial distribution of the different classes across different types of place, and that some of the mortality differences by social class might actually reflect the contextual effects of healthy and unhealthy places. Although this line of argument has received a considerable amount of attention in health geography literature, it has rarely been examined for a specific historic period, and then only within particular urban areas. In this paper, we apply multi-level models to a complete count individual-level dataset of the 1911 census of England and Wales, comparing influences on infant and child mortality at the level of the individual couple and for two spatial levels. We find that although most variation in infant and child mortality operates at the individual level, there is also important variation at the two spatial levels and part of the mortality differences between social classes is better explained by the areas in which people lived rather than by their social class. A consideration of independent variables at all three levels suggests that different spatial scales capture different sorts of influences on early age mortality.

Ireland is often seen as an outlier within the western world in terms of demographic behavior. As a society it has also been noted for its religious fervor, including religious division, at least until fairly recently. Might there be connections historically between these two spheres? One intriguing area of enquiry relates to possible links between religious denomination and child mortality. We explore this possibility using individual-level data from the household schedules of the Irish Census of 1911. The study area is Belfast, Ireland’s leading industrial city, which allows for a wide range of occupational and social class differences. Combining regression techniques and the mortality index proposed by Preston and Haines (1991), we seek to tease out the relationship between child mortality and religious affiliation while controlling for a range of other explanatory variables. We show that religious identity is clearly associated with different infant and child mortality outcomes. Of the three major religious denominations, Catholics suffered the most from high infant mortality, Church of Ireland (Anglican) families were only a little better off, while the largest Protestant denomination, the Presbyterians, had the best infant mortality outcomes. These differences were related, in the main, to the varying socioeconomic composition of the three major religious denominations but religious affiliation also mattered in its own right.

In this paper, we study differential infant and child mortality according to the origin of the mothers, natives of Madrid or immigrants, between 1916 and 1926. From 1880 to 1939, Madrid experienced spectacular demographic growth, with a massive influx of immigrants, mainly from the Castilian Plateau. Using the city’s records of births and deaths, which we linked for the study period, we demonstrate an important spatial heterogeneity in infant and child mortality across the city. Although the development of the town was planned in the 1860s, the infrastructure and the real estate market were overwhelmed by the continuous arrival of new inhabitants. Moreover, major investments in public health increased the gap between the wealthy districts and peripheral areas. These improvements deepened inequality. During years marked by the waves of the influenza pandemic, we isolate the impact of poverty, which threatened the survival of newborns through poor nutrition, deficient hygienic infrastructures and deplorable housing conditions. Such features explain the impressive association between summer and the risk of dying from enteritis, diarrhea and other diseases of the same type among weaned children. However, the mortality differentials between the offspring of native and migrant mothers were surprisingly small, which we explained in terms of behavioral adaptation to the large city and its mass society.

In the first half of the twentieth century, deaths from infectious disease, especially among the very young, fell dramatically in American cities. However, as infant mortality fell and life expectancy rose, racial inequality in urban infectious disease mortality grew. In this paper, we show that the fall in mortality and the rise in racial inequality in mortality reflected two countervailing processes. The dramatic decline in infant mortality from waterborne diseases drastically reduced the total urban infectious disease mortality rate of both Black and white Americans while having a comparatively small effect on the total racial disparity in urban infectious disease mortality. In contrast, the unequal fall in tuberculosis mortality, particularly in the prime of life, widened racial inequality in infectious disease mortality in US cities.

This paper shows the effect that the medical expertise of medical practitioners had on the life chances of their children. We focus on infant and early childhood mortality. We reconstructed the life histories of the offspring of a group of around 2800 medical practitioners who were practicing in a high-mortality region in the Netherlands between 1850 and 1922, the period during which infant and child mortality in the Netherlands underwent the largest changes. The survival of their offspring is compared with that of a random sample of children from the Historical Sample of the Netherlands. Multilevel hazard analysis, using Cox proportional hazards models with shared frailty, is applied to study the effect of belonging to the medical profession on survival, in relation to the level of infant mortality in the regions where children were born. Within the group of medical practitioners, attention is paid to differences in children’s survival according to the level of medical knowledge of the fathers. Our statistical analyses show that the offspring of medical practitioners as a whole did have better survival prospects than children born to families without a father with a medical background. When medical practitioners had effective medical knowledge, measured by the period of graduation and the highest level of medical training reached, the positive effects on the survival of their children were even stronger.

This is a history of the creation of the book Fatal Years: Child Mortality in late-Nineteenth-Century America (1991) by the authors. The data were a sample of households from the 1900 United States Census manuscripts. The primary method used was indirect estimation of child mortality (approximately ages 0–4) using information on the age and marriage duration of women. Among the findings were overall lower overall mortality than in the 1900/1902 Glover life tables for the Death Registration Area, and very large variations in mortality by race and size of place of residence.
