Fertility in England and Wales: A Fifty-Year Perspective

This paper provides a detailed account of fertility levels and trends in England and Wales since 1938, with a briefer coverage of a much longer time-span. The paper is concerned both with the measurement of fertility and with understanding the observed fertility behaviour. We lament and correct the failure of demographers to apply measurement tools available since the 1950s to the analysis of fertility in England and Wales, with a particular emphasis on adjustment of period measures and period parity progression ratios and show how some of the grosser errors of analysis and interpretation might have been avoided by earlier use of these approaches. We also relate these estimates to more recent ones. Once a clearer account of trends has been established, the paper goes on to reinterpret and explain the baby boom and baby bust. The conclusion looks at future prospects for fertility.     

Cohort nuptiality in England and Wales

Summary A computerized nuptiality system, called GENMAR, has been developed to investigate trends in cohort nuptiality in England and Wales. This system has five main programmes dealing with first marriage, the effects of changes in mortality on nuptiality measures, divorce, re-marriage, and marital status distribution. This paper summarizes the results of the application of the first programme to England and Wales data on first marriages of persons who were born in every single year since 1900. GENMAR-1 generated for each of these cohorts a 'complete' gross nuptiality table. The analysis shows that there have been substantial increases in the intensity of first marriage at young ages, a downward shift in the modal age at marriage, and a significant rise in the proportion ever married among women. The cohort nuptiality tables also show that the change in the nuptiality of women was due to changes in both the tempo and level of nuptiality, whereas the change for men was mainly the effect of shifts in the temporal pattern of nuptiality. There are, however, signs of a slow down of marriage among the cohorts born since the early 1950's.     

Age at marriage and marital fertility

In recent years much criticism has been levelled against the use of gross and net reproduction rates as measures of replacement in any period of marked change. In this paper the author considers these criticisms and outlines a method which would yield more information on the problem of replacement and which would also eliminate the influence of varying ages at marriage on fertility when different groups or periods of time are compared. The use of this method is illustrated by an application to the fertility statistics of England and Wales and of different counties.     

Timing effects on first marriage: twentieth-century experience in England and Wales and the USA

Recent substantial declines in first marriage in Western countries have been accompanied by increases in the average age at first marriage. Since the period proportion ever marrying, PEM, is sensitive to cohort tempo changes, the recent fall in the PEM may simply reflect cohort delays in marriage. The importance of timing factors is examined in the light of twentieth-century experience of first marriage in England and Wales and the USA. Using a variant of the Timing Index developed in research on fertility, we measure cohort timing effects for marriage and calculate an adjusted PEM. After examining twentieth-century trends in nuptiality for men and women, we find substantial tempo effects on the period PEM. Adjusted PEM values show a real decline in marriage for cohorts, but that decline is considerably smaller than the one shown by the unadjusted figures. This is especially true for England and Wales, where the decline in marriage was much greater.     

The fertility of teachers in England and Wales

Data on the fertility of teachers in grant earning schools in England and Wales were collected in 1955 as part of a general survey into the social characteristics of teachers. The survey was financed by the Nuffield Foundation with a contribution from the Population Investigation Committee. A subsequent article will discuss some possible determinants of fertility and in particular the interrelationship between social mobility and fertility. The present note describes changes in cohort fertility of teachers since 1915 and compares average family size with that of other sections of the population. The average number of children per married male teacher declined from 1.81 for the pre-1920 cohort to 1.47 for 1930–34. Segmental data after 1935 indicate a rise to approximately 2 children per family. Comparison with the Family Census suggests that the number of children of teachers is between 10% and 20% below that of all professions combined when the age at marriage of the wife is taken into account.     

The end of “Catholic” fertility

Catholic and non-Catholic fertility during the post-World War II period are compared in this paper. Evidence accumulated across five sample surveys of fertility in the United States, which were conducted at five-year intervals from 1955 through 1975, forms the basis for the analysis; both cohort and period measures are employed. Starting from a situation where Catholic fertility was very little higher than that of non-Catholics, it is shown that the differential increased markedly during the baby boom and then declined to a point where the two trends nearly come together in the mid-1970s. Interpretation of the recent convergence in the light of various theories that have been put forward to explain the differential suggests that it will be an enduring phenomenon.     

Adapting the Own Children Method to allow comparison of fertility between populations with different marriage regimes

The Own Children Method (OCM) is an indirect procedure for deriving age-specific fertility rates and total fertility from children living with their mothers at a census or survey. The method was designed primarily for the calculation of overall fertility, although there are variants that allow the calculation of marital fertility. In this paper we argue that the standard variants for calculating marital fertility can produce misleading results and require strong assumptions, particularly when applied to social or spatial subgroups. We present two new variants of the method for calculating marital fertility: the first of these allows for the presence of non-marital fertility and the second also permits the more robust calculation of rates for social subgroups of the population. We illustrate and test these using full-count census data for England and Wales in 1911.     

Size and structure of the household in England over three centuries

Abstract Data giving sizes and structures of households have been rare for any country before the institution of the official census, and have to be gleaned from surviving documents containing listings of inhabitants. This article, the first of two, describes the collection of listings of inhabitants of English communities which is being assembled by the Cambridge Group for the History of Population and Social Structure and the methods by which the hundred most informative of them have been submitted to analysis. When ranged alongside the information on mean household size derived from the official British census since its inception in 1801, the results of this analysis suggest the following. 1. Mean household size in England and Wales as a whole was relatively constant at 4·75 or a little below for the whole period from the sixteenth century until 19II, and has only fallen since that date. The reduction of about one-third starting in 1921 may therefore be the first of considerable magnitude ever to occur: it seems to have been particularly rapid between 1911 and 1931. 2. Mean household size in England and Wales has been surprisingly resistant to demographic fluctuation on the one hand and to the structural influences of industrialization on the other, until the last fifty or sixty years. 3. The traditional household in England has never been extended on any definition, at least since the sixteenth century. Mean household size varied with social status, and a majority lived in households of six or more members. But this distribution was due to the very large numbers of servants living in and not to the presence of resident kin, who seem to have been rare. 4. The relationship between fertility, mortality and mean household size is different from what has been supposed. This article ends by registering the paradox that proportion of children in a pre-industrial English community apparently seems to be negatively, not positively, related to its mean household size, and this theme will be taken up in the second article. These four points are illustrated by a series of tables drawn from the analysis of the one hundred communities.     

Cohort Reproductive Patterns in Low‐Fertility Countries

This account reports on a project in progress that aims to obtain a comprehensive picture of contemporary fertility levels and trends in 27 low‐fertility countries. Cohort analysis is applied to review the fertility experience of women born from the 1930s through the 1970s. This choice of dates ensures that not only completed fertility but also the fertility patterns of women in the midst of or near the onset of their reproductive period are examined. In most of the 27 countries, completed fertility of successive cohorts has been declining. It appears plausible that the trends discerned in the analysis will continue in the foreseeable future. For these trends to be reversed, women who are about to enter or who are in the midst of their reproductive periods would have to adopt fertility patterns markedly different from those of women born in the 1960s and 1970s.     

The effect of long-term migration dynamics on population structure in England & Wales and Scotland

We investigated the effect of migration on population dynamics in England & Wales and Scotland from the mid-nineteenth century to the present by comparing actual population size and structure with estimates based on zero net migration from a range of starting dates. In this period, Scotland had the largest net outflow among countries in Europe for which detailed information is available, whereas overall net migration in England & Wales was close to zero. In the absence of migration, population would have been over twice as large in Scotland in 2013 as the actual value, but similar to its actual value in England & Wales. Levels and pace of population ageing have been broadly similar in both countries, so the major impact of differential migration has been on population size rather than structure. We discuss these findings in relation to the debate on migration policy between political parties supporting and opposing independence in the 2014 Scottish referendum.     

A demographic explanation for the recent rise in European fertility

Between 1998 and 2008 European countries experienced the first continent-wide increase in the period total fertility rate (TFR) since the 1960s. After discussing period and cohort influences on fertility trends, we examine the role of tempo distortions of period fertility and different methods for removing them. We highlight the usefulness of a new indicator: the tempo- and parity-adjusted total fertility rate (TFRp*). This variant of the adjusted total fertility rate proposed by Bongaarts and Feeney also controls for the parity composition of the female population and provides more stable values than the indicators proposed in the past. Finally, we estimate levels and trends in tempo and parity distribution distortions in selected countries in Europe. Our analysis of period and cohort fertility indicators in the Czech Republic, Netherlands, Spain, and Sweden shows that the new adjusted measure gives a remarkable fit with the completed fertility of women in prime childbearing years in a given period, which suggests that it provides an accurate adjustment for tempo and parity composition distortions. Using an expanded dataset for ten countries, we demonstrate that adjusted fertility as measured by TFRp* remained nearly stable since the late 1990s. This finding implies that the recent upturns in the period TFR in Europe are largely explained by a decline in the pace of fertility postponement. Other tempo-adjusted fertility indicators have not indicated such a large role for the diminishing tempo effect in these TFR upturns. As countries proceed through their postponement transitions, tempo effects will decline further and eventually disappear, thus putting continued upward pressure on period fertility. However, such an upward trend may be obscured for a few years by the effects of economic recession.     

Cuba: the demography of revolution

Cuba's post-revolution demographic trends, especially in regard to fertility and emigration, and the causes and consequences of these trends, were examined using available statistical data. The authors maintain that both fertility and emigration trends were highly infuenced by economic factors. The trends are described in the context of the social and economic changes instituted by the revolutionary government. Government policies were aimed at 1) eradicating inequalities in housing, income, education, and health; 2) improving the status of women; and 3) upgrading the living standards of the rural population. Government policies did alleviate many social problems and greatly improved the health and educational status of the population; however, these policies had a marked adverse effect on economic performance. The demographic transition began in Cuba earlier than in most other developing countries and it began long before the 1959 revolution. These earlier changes must be taken into account when assessing the impact of post-revolution policies on demographic trends. Cuba's birthrate declined from 26-14.8/1000 population between 1959-1979 and the total fertility rate declined from 3.7-1.9 between 1970-1978; however, during the 1960s there was a baby boom and the birth rate for 1963 exceeded 35/1000 population. The baby boom was largely a response to the temporary improvement in economic conditions which occurred shortly after the revolution. The decline in fertility during the 1970s was due in part to the increased availability of abortion and contraceptive services and to a decline in the marriage rate; however, Cuba's deteriorating economy was also a major contributing factor. The baby boom of the 1960s is negativley affecting the current economy of the country. Individuals born during the baby boom are entering adulthood and are contributing toward Cuba's current unemployment problems. Prior to the revolution, Cuba experienced a high rate of in-migration. Immediately after the revolution this pattern was reversed and between 1959-1980 more than 800,000 Cubans emigrated. Most of these emigrants went to the U.S. A large proportion of the earlier emigrants were members of the upper and middle socioeconomic classes. Recent emigrants were more evenly representative of all segments of Cuba's population. The socioeconomic characteristics of the emigrants are described and their adjustment in the U.S. is discussed. Tables provide statistical data on Cuba's demographic trends.     

On the tempo of childbearing in England and Wales

Abstract The paper describes a computerized model developed to simulate the fertility of a hypothetical marriage cohort in a closed population. The model was applied to England and Wales fertility data of marriage cohorts of the years 1951 to 1970. For each of these cohorts, the computer was programmed to construct five series of tables showing birth-order probabilities, family size frequency distribution, mean length of intervals between marriage and successive births, parity progression ratios and mean family sizes of fertile women. The results showed that the fertility of the cohorts of women who married between the middle 1950s and the early 1960s was character ized by a declining trend in the frequency of childlessness and by a dramatic increase in the proportion of marriages with two or more children. Since 1964 or so, there has been a downward trend in duration-specific birth-order probabilities. The analysis suggests that the recent drop in fertility may well prove to be the effect of an upward shift in the timing of births as well as a fall in completed fertility.     

Reproductive history and mortality later in life: a comparative study of England and Wales and Austria

Does a woman's reproductive history influence her life span? This study explores the question with data from the contemporary female populations of England and Wales and Austria. It is the first comparative study to investigate the relationship between fertility and mortality late in life. We find similar patterns and age-specific trends of excess mortality in both populations: parity significantly influences longevity, as do both an early and a late birth. These differences in longevity are not explained by differences in educational or family status. The impact of a woman's reproductive history on her life span is small, however, compared to the influence of her level of education or family status.

Armed Conflict and the Timing of Childbearing in Azerbaijan

Research on fertility changes in former Soviet states of the South Caucasus is scant and has overlooked the role of armed conflicts. This study contributes to filling these gaps by providing the first detailed account of fertility changes in Azerbaijan since independence and by exploring them in relation to the Nagorno-Karabakh conflict with Armenia. Estimates from retrospective birth history data from the 2006 Demographic and Health Survey show that since 1991 period fertility declined to almost below-replacement levels, essentially as a result of stopping behavior, and, only recently, slight birth postponement. While the conflict seems to have little influence on aggregate trends, discrete-time logit models accounting for unobserved heterogeneity reveal a 42–45 percent higher risk of transitioning to the second birth for women who have been exposed to conflict violence—whether in the form of forced migration or because of residence in the conflict-torn Karabakh region—than for nonexposed women. Never-migrant women from Karabakh have also significantly higher probability of having a first child. Further positive effects on fertility are observed for women who lost a child during peak conflict years. Risk-insurance and replacement effects are possible mechanisms explaining such fertility responses.     

Demographic responses and socioeconomic structure: Population processes in England and Wales in the nineteenth century

This paper explores some theoretical and empirical aspects related to the theory of change and multiple response. The empirical analysis focuses on 600 relatively small and homogeneous geographical units of England and Wales for the period 1851-1910. These units are classified into six identifiable socioeconomic types and the analysis is male for each of them. Two interrelated tissues are studied. First, a set of explanatory variables, connected either with strain or with factors relieving strain, is constructed. The effects of these explanatory variables on nuptiality, marital fertility, and migration responses are examined for each socioeconomic type, with respect to their significance, intensity, and direction. The patterns of these effects show general consistency with multiphasic response considerations for all socioeconomic types. A significant finding in this part is that migration affects very strongly the intensity of the marital fertility decline response. The second issue deals with theoretically expected patterns of interrelationships among responses in terms of substitutability and complementarity. The theoretical interrelationships are compared with the empirical for each socioeconomic type; and in general, consistency is established. Moreover, these interrelationships can be interpreted for each socioeconomic type in a way that appears to be consistent with multiphasic response considerations. An important finding in this part is that emigration and marital fertility decline are substitute responses in agricultural-based districts. Implications of the findings are discussed.     

On the pattern of cohort fertility

Abstract An examination of the patterns of cohort fertility rates in a number of populations revealed the existence of a common pattern showing how mean family sizes of the different age-at-marriage groups of a given marriage cohort are built up over the reproductive span. Standard schedules of fertility patterns are generated by the use of the Gompertz function which defines the distribution of cumulative fertility rates of a given marriage cohort by marriage duration by means of only three parameters. The generated system is tested with the historical series for England and Wales and Sweden and is found adequate to describe widely different childbearing patterns. Some of the demographic implications of the existence of common fertility patterns are examined and the usefulness of the generated system in projecting future fertility trends is briefly discussed.     

曲折、艰难、辉煌的中国生育转变

Fertility Transition in China:A Zigzag and Splendid Course

Examining China’s population changes in the past three decades demonstrates that China’s demographic transition has been successfully completed with a splendid and zigzag path.There are profound historical experiences and lessons.This paper reviews China’s fertility transition which is divided into four periods and argues that fertility changes are a result of the interactions between socioeconomic development,fertility behaviors and fertility policies.Substantial resistance to the "one-childpolicy" during 1979 to 1984 resulted in rebounding and fluctuating fertility.The baby boom occurred in the period 1985 to 1991 was a manifestation of the inherent laws of demographic dynamics,and subsequently forceful birth control was again mobilized.The period from 1992 to 1999 witnessed large declines in fertility which penetrates the replacement zone,showing that China was completing the fertility transition.China’s stabilizing low fertility and emerging population structural issues since 2000 call for comprehensive ways in addressing the population problems.
