Why does Sweden have such high fertility?
Full text linkBy current European standards, Sweden has had a relatively high fertility in recent decades. During the 1980s and 1990s, the annual Total Fertility Rate (TFR) for Sweden undulated considerably around a level just under 1.8, which is a bit lower than the corresponding level in France and well above the level in West Germany. (In 2004 the Swedish TFR reached 1.76 on an upward trend.) The Swedish completed Cohort Fertility Rate (CFR) was rather constant at 2 for the cohorts that produced children in the same period; for France it stayed around 2.1 while the West-German CFR was lower and declined regularly to around 1.6. In this presentation, I describe the background for these developments and explain the unique Swedish undulations.fertility trends, Germany, impacts of family policies, institutional effects, Sweden
Patterns of twinning for Swedish women, 1961-1999
Full text linkThe Nordic population registers provide a unique possibility to study the demographic behavior of small population groups and rare events. In this paper, we study the childbearing behavior of Swedish mothers of twins between 1961 and 1999, inclusive. The twinning rate has increased since the mid-1970s in response to a growing use of fertility-stimulating treatments such as in-vitro fertilization. Such medical procedures are applied mainly to women beyond prime childbearing ages. Nevertheless, we find no simple age pattern in twinning rates. They do not just increase with the woman´s age. Our most consistent finding is that mothers of twins wait noticeably longer than women with singletons before they have another child. This apart, mothers with twins at their first birth have next-birth fertility patterns very similar to women who have two singletons at their first two births. This commonality in childbearing behavior does not extend to higher-order births, though. For mothers with a singleton and a pair of twins, the progression to a third birth depends very much on whether the twins came first or second. We also discover that at parities beyond 3, twinning rates increase with parity, especially at very short durations since the previous birth.vital events
Why does Sweden have such high fertility?
Full text linkBy current European standards, Sweden has had a relatively high fertility in recent decades. During the 1980s and 1990s, the annual Total Fertility Rate (TFR) for Sweden undulated considerably around a level just under 1.8, which is a bit lower than the corresponding level in France and well above the level in West Germany. (In 2004 the Swedish TFR reached 1.76 on an upward trend.) The Swedish completed Cohort Fertility Rate (CFR) was rather constant at 2 for the cohorts that produced children in the same period; for France it stayed around 2.1 while the West-German CFR was lower and declined regularly to around 1.6. In this presentation, I describe the background for these developments and explain the unique Swedish undulations. Part of the explanation of the trend and level in Swedish fertility is the extensive battery of public family policies in the country. They reflect the great generosity, high flexibility, and universalistic approach of the whole system, where family policies are coordinated with educational policies and labor-market policies in an effort to promote the status of women and achieve equity for all residents. The state has been engaged in the development of high-quality all-day childcare arrangements available to all children, and has conducted campaigns to influence public attitudes toward a woman-friendly political culture. Reforms have been motivated by gender-equality considerations and by a drive to induce women to participate in the labor force and to induce men into parenting and childrearing. Legal rules are individualistic, as highlighted by the abolishment of the public widow’s pension and by a tax system where income tax is levied from the individual and not from the married couple or the household, as in Germany. Welfare-state benefits are directed similarly to the individual, not to the family. Policies can be said to focus on the equal right of working women to have children rather than of the right of mothers to have a job. There is no inclination in the Swedish system to encourage a mother to stay home and take care of her children; if anything there has been a move toward securing both-parent participation in childrearing.Sweden, fertility
Childbearing patterns for Swedish mothers of twins, 1961-1999
Full text linkThe Nordic population registers provide a unique possibility to study the demographic behavior of very small population groups and rare events. In this paper, we study the childbearing behavior of Swedish mothers of twins between 1961 and 1999, inclusive. Our most consistent finding is that mothers of twins wait noticeably longer than women with singletons before they have another child. This apart, mothers with twins at their first birth have next-birth fertility patterns very similar to women who have two singletons at their first two births. This commonality in child-bearing behavior does not extend to higher-order births. For mothers with a singleton and a pair of twins, the progression to a third birth depends very much on whether the twins came first or second. Beside these main results our fascinating material also provides a number of descriptive findings. The Swedish twinning rate has increased since the mid-1970s in response to a growing use of fertility-stimulating treatments such as in-vitro fertilization, in parallel with similar developments in many other countries. Such medical procedures are applied mainly to women beyond prime childbearing ages. Nevertheless, we find no simple age pattern in twinning rates. Even in recent years they do not just in-crease with the woman’s age. By way of contrast, at parities beyond 3 twinning rates increase with parity when we control for calendar period, time since last previous birth, and (NB) the woman’s own age.Sweden, twin studies
In Memoriam: Professor Jan M. Hoem
Full text linkJan Hoem died on Saturday in Stockholm after a long illness. Jan became Director of the Max Planck Institute for Demographic Research (MPIDR) in 1999; he and I jointly led the Institute for almost eight years. During this period he served as Editor of Demographic Research; he took on this responsibility shortly after the journal was launched and built the journal into a respected online source of cutting-edge analysis. Jan was a superb colleague, with very good judgment, a delightful sense of humor, and deep devotion to research quality. A pioneer of event history analysis, he understood the subtleties of the subject better than anyone else. Jan was born and educated in Norway and worked in Oslo before becoming Professor in Copenhagen and then Professor in Stockholm, where he established SUDA, a leading demographic research initiative. His dedication to high-quality, statistically sophisticated population research at SUDA and MPIDR as well as in the journal Demographic Research substantially advanced the discipline of demography. Jan was a warm and generous teacher, a loyal colleague, and a caring friend whom many people will long remember with gratitude and respect. James W. Vaupel Publisher, Demographic Researc
