The impact of induced abortion on black and white birth outcomes in the United States

This paper examines the impact of induced abortion on birth outcomes by treating abortion as an endogenous input into the production of infant health. To gauge the direct and indirect effects of abortion, three measures of infant health are considered simultaneously: the neonatal mortality rate, the percentage of low-weight births, and the percentage of preterm births. All three are race specific and all pertain to large counties in the United States in 1977. The results suggest that by preventing unwanted births, abortion enhances the survivability of newborns of a given birth weight and improves the distribution of births among high-risk groups.     

Determinants of temporal and areal variation in infant mortality in Germany, 1871–1933

This article investigates how sociodemographic, economic, medical, and public health factors influence infant mortality by using data about German administrative areas from 1871 to 1933. Marital fertility has the largest impact on infant mortality, followed by illegitimacy, medical care, urbanization, and infant welfare centers. The variables considered here account for most of the variation in infant mortality. Some of the unexplained variance is due to factors associated with regions, such as breastfeeding patterns, and with time periods, such as national health insurance. The analyses found no evidence that advances in medical technology affected infant mortality or that the influence of economic development changed over time.     

The effect of legalization and public funding of abortion on neonatal mortality: An intervention analysis

This paper examines the impact of the legalization of abortion on neonatal mortality in the United States. Monthly time series data are used to estimate intervention models separately for the U.S. as a whole and for the States of New York and South Carolina. Legalization of abortion in 1973 is found to have no discernible impact on national neonatal mortality rates. However, results from New York and South Carolina, states in which accessibility and public funding of abortion differed markedly, suggest that abortion is significantly related to declines in neonatal mortality, particularly among nonwhites. The magnitude and timing of such impacts varied between races and states.     

The linked survival prospects of siblings: Evidence for the Indian states

This paper reports an analysis of micro-data for India that shows a high correlation in infant mortality among siblings. In 13 of 15 states, we identify a causal effect of infant death on the risk of infant death of the subsequent sibling (a scarring effect), after controlling for mother-level heterogeneity. The scarring effects are large, the only other covariate with a similarly large effect being mother's (secondary or higher) education. The two states in which evidence of scarring is weak are Punjab, the richest, and Kerala, the socially most progressive. The size of the scarring effect depends upon the sex of the previous child in three states, in a direction consistent with son-preference. Evidence of scarring implies that policies targeted at reducing infant mortality will have social multiplier effects by helping avoid the death of subsequent siblings. Comparison of other covariate effects across the states offers some interesting new insights.

Public policy and the total fertility rate: cross-sectional evidence from the LDCs

A framework developed by Easterlin for the analysis of fertility in developing societies is modified and then tested using a sample of 65 less-developed countries. The focus is on assessing the impact of public policy on the national fertility rate. Public policy is reflected in the average levels of education and health in the population and in the condition of the national family planning program. To test for threshold effects with respect to socioeconomic development, the sample is divided on the basis of the infant mortality rate. Fertility rates in those nations characterized by high infant mortality are likely to be determined more by conditions of natural fertility. Those nations with lower infant mortality, and hence greater socioeconomic development, are more likely to exhibit deliberate fertility control. The results of the regression analysis do suggest that different factors influence the national fertility rate depending upon the stage of development. For the least-developed nations, the secondary school enrollment rate, an indicator of the extent of economic mobility, and the ratio of school age children to teachers, a proxy for the national commitment to human capital formation, are important. For the more advanced of the LDCs, adult literacy and the infant mortality rate seem to predominate. For all the developing nations, however, the results confirm the importance of strong family planning programs. The paper concludes with a discussion of the policy implications of the research.     

The population situation and its relation to the economy in Turkey]

In southwest Asia, Turkey is a leading nation in collecting complete data on its population through the use of a modern census. Based on available information, the development of Turkey's population can be summarized as follows: 1) in the last 20 years, Turkey's population increase rate has been 2% annually, very high by world standards; 2) the average age is young, and the population's burden coefficient is above 80%; and 3) the geographical distribution of the population is uneven. The population density in central, eastern, and southeastern parts of the country is low, while the coastal provinces near the Black Sea, Mediterranean Sea, and Aegean Sea have a high population density. In the last 50 years, the political situation in Turkey has remained stable. The national economy has developed rapidly, and the infant mortality rate has declined as a result of advancements in medicine and health care. Since Turkey is an Islamic country, birth control and abortion are not popular. The traditional early marriage for women and high illiteracy rate among women have contributed to a rapid population growth. In the past 20 years, however, the national economy has been overburdened by a rapid population growth. Problems of unemployment, a housing shortage in cities, inadequate public health facilities, a shortage of schools, a decline in farm land and inadequate food supplies have become increasingly obvious. Economically speaking, Turkey is much better than most developing nations. With its current foundation and rich natural resources, the country needs only to reduce the natural population increase rate slightly in order to achieve a balanced economic development.     

Indicators of contraceptive policy for nations at three levels of development

The study is concerned with examining variations in contraceptive policies among 74 nations of the world. Employing quantitative data collected by the United Nations, the national policies for three types of contraceptive devices (birth control pills, condoms and IUDs) were examined for nations at three levels of development. The policies for the three items were found to be highly intercorrelated. Given this fact, a restrictiveness index related to the commercial sale of the three types of contraceptive was constructed. A set of independent variables was then related to this restrictive index employing multivariate analysis. The results differed appreciably for the developed and non-developed nations. For the developed nations restrictiveness was significantly related to the fertility rate and the number of physicians in the society, whereas for the developing nations it was significantly related to the infant mortality rate in the society.     

An analysis of population growth in Romania]

After liberation in Romania the high birth rate, high mortality rate, and high population growth rate pattern changed to a low birth rate, low mortality rate, and low growth rate pattern. Higher standard of living and educational level, the increasing involvement of women in social and economic activities, the rapid development of cities, and the lower infant mortality rate are the 4 main factors responsible for this development. Consequently, Romania is facing a problem of increasing labor shortages. People who would otherwise be in the labor force are in school to allow the rapid development in science and technology. The increasing proportion of older retirees in the population also decreases the labor supply. Agricultural mechanization has provided labor to support industrialization in the past. Future increases will emphasize irrigation and soil improvement rather than mechanization. The Romanian government has established 6 new laws to stimulate population growth. First, award bonuses to families with more children and tax childless couples. Second, eliminate factors destabilizing families, preference to young couples, and restrict abortion and divorce. Third, protect women's societal rights through bonuses to mothers and paid maternity leave to pregnant women. Fourth, reduce mortality rate and improve people's health and life span. Fifth, better utilize the labor force and redistribute the population by economic methods. Six, use longterm procedures to achieve the best population structure and to have a younger population.     

Famine,Maternal Nutrition and Infant Mortality: A Re-examination of the Dutch Hunger Winter

During the Dutch Hunger Winter (1945), a unique, documented example of mass famine in an industrialized population, total reproductive loss (fetal and infant mortality) among most exposed mothers remained relatively low. This is explained by highly favourable fetal mortality and unfavourable infant mortality. The author traces the pattern of low fetal mortality to the higher levels of ‘embodied health status’ of famine mothers. The high infant mortality of the famine area testifies to the severity of the food and fuel shortage, yet another factor held down the rate of stillbirth. This other factor, it is argued, has a socio-economic character, it is the intrinsic ‘embodied’ nutritional status of the regional population, arising from favourable opportunities for growth and development among successive generations of mothers. This explanation highlights the importance of maternal vitality, (a synthetic, historically variable and culturally determined phenomenon) as a neglected feature of historical demography.     

Sex Ratio at Birth and Infant Mortality Rate in China: An Empirical Study

In this article, we used the data from the last three population censuses of China in 1982, 1990 and 2000, to study the dynamics of the sex ratio at birth and the infant mortality rate in China. In the late 1970s, China started its economic reform and implemented many family planning programs. Since then there has been great economic development and a dramatic decrease in fertility in most of its provinces. Along with these achievements, the sex ratio at birth of the Chinese population has increased to significantly more males to females, and in some provinces of China reached unprecedented levels. The ratio of infant mortality of the males to females for manyprovinces in China become extremely unbalanced with a much higher female infant mortality rate. In our study, we investigated the statistical relationship between the sex ratio at birth and the ratio of the infant mortality of males to female. Social and economic reasons for these unnatural trends are also discussed.     

Determinants of Infant Mortality in Older ASEAN Economies

Infant mortality in the Association of Southeast Asian Nations (ASEAN) has been declining, yet disparities remain between the nations. This paper therefore explores the determinants of infant mortality in the older ASEAN-4 economies, Malaysia, Thailand, Indonesia and the Philippines using an Autoregressive Distributed Lag (ARDL) Error Correction Model framework. The key findings of the study are: First, there is evidence of long-run relationships among infant mortality, education, female fertility, income and access to healthcare. Second, the determinants of infant mortality vary between countries. Female fertility emerged as the main determinant of infant mortality in Malaysia, while access to healthcare matter for infant mortality in Indonesia, and to a lesser extent for the Philippines. The income effect is significant for reducing infant mortality in Malaysia, while female education is important for Indonesia and Thailand. Third, the speed of adjustment of infant mortality rate is comparatively low in ASEAN-4.     

Infant Mortality and Socioeconomic Status: New Bottle,Same Old Wine

This paper presents the results of an ecological analysis of the relationship between infant mortality and economic status in metropolitan Ohio for the period 1960–2000. The data examined are centered on the five censuses undertaken during this 40-year period. The basic unit of analysis is the census tract of mother’s usual residence, with economic status being determined by the percentage of low income families living in each tract. For each of the five periods covered, census tracts were aggregated into broad income areas and three-year average infant mortality rates were computed for each area, by age, sex, race and exogenous-endogenous causes of death. The most important conclusion to be drawn from the data is that in spite of some very remarkable declines in infant mortality at all class levels since 1960, there continues to be a very clear and pronounced inverse association between income status and infant mortality. Indeed, the evidence indicates that the relationship has become stronger over the years. These observations are applicable for both sexes, for whites and nonwhites, for neonatal and postneonatal deaths, and for both major cause of death groups. It is concluded that while public health programs are important, any progress in narrowing this long-standing differential is unlikely unless ways can be found to enhance the economic well-being of the lower socioeconomic groups.     

Fertility decisions when infant survival is endogenous

There is evidence that fertility is positively correlated with infant mortality, and that a child‘s chance of surviving to maturity increases with the level of nutrition, medical care, etc. received in the early stages of life. By modelling parental decisions as a problem of choice under uncertainty, the paper shows that fertility and infant mortality are most likely to move in opposite directions if, as implicitly assumed by existing economic theories, parents believe that there is nothing they can do to improve the survival chances of their own children. By contrast, if parents realize that those chances improve with the amount they spend for the health, nutrition, etc. of each child that they put into the world, then fertility and infant mortality may move in the same direction. Under such an assumption, the model has the strong policy implication that directly death-reducing public expenditures are most effective, but stimulate population growth, at low levels of development. By contrast, at high levels of development, such expenditures tend to crowd out parental expenditures, and are a factor in fertility decline. Received: 14 October 1996 / Accepted: 28 July 1997     

Socio-economic determinants of mortality in Latin America

The characteristics and sources of socioeconomic differentials of mortality in Latin America, in so far as they are currently known, are examined in an attempt to clarify the present situation and its perspectives. Mortality in a population is a function of the frequency of illness (incidence) and the probability of dying of the sick individual (lethality). Information on the socioeconomic differentials of mortality in Latin America is systematically reviewed with attention directed to the following: differentials among Latin American countries, regional differences within countries, urban-rural contrasts in mortality, mortality and income level and level of education, and mortality and ethnic groups. Latin America shows considerable heterogeneity with respect to the risk of dying, which varies from 202/1000 births in Bolivia to 38/1000 in Uruguay. It is estimated that more than 1/2 of the children born in Latin America are exposed to a mortality rate of over 120/1000. A study of the urban and rural populations of 12 Latin American countries revealed that the risk for rural populations exceeds that for urban populations by 30-60%. There is extensive evidence showing that mortality is higher in the working class and is associated with lower levels of education and income. Mortality was also higher in certain indigenous groups. Socioeconomic differentials of mortality are more marked in Latin America than in the developed nations. The mother's level of educational attainment is the variable most significantly associated with infant and child mortality. The prospect of reducing the current mortality levels is dependent primarily upon the implementation of policies aimed at a more egalitarian distribution of the benefits of socioeconomic development among the population.

Neo-natal and post-neo-natal mortality in a rural area of Bangladesh

Abstract An analysis of neo-natal and post-neo-natal mortality in 132 villages (population of 117,000) of Matlab thana indicates the following: (i) Neo-natal deaths accounted for 60% of the infant mortality rate of 125. This proportion was unexpectedly high since previous research had maintained that in countries with infant mortality rates over 100, neo-natal deaths account for less than one-third of all infant deaths. Since the present findings on the proportions of neo-natal deaths correspond exactly with results from an earlier registration system in East Pakistan, it is suggested that the long-accepted proposition, 'less developed' areas are characterized by lower proportions of neo-natal deaths than 'more developed' areas, be re-examined. (2) The infant death rate accounts for 36% of all deaths in the population. If the infant death rate were reduced by half the result would be a decrease in the current crude death rate from 16 to 13. Although this reduction would appear to be small, in the context of a current high growth rate of 3% (from 1966-67 to 1968-69) it exerts a sizeable impact. For example, it would take a reduction of eight points in the crude birth rate of 46 just to achieve a growth rate 2·5% under these circumstances. Obviously, continued efforts in death control without an effective birth control programme will perpetuate high rates of growth. (3) Neo-natal and post-neo-natal mortality exhibited the -expected 'U' shaped pattern with parity, and generally varied as expected with age and family size, except in the oldest age group and largest family size where the risk was smaller than in the preceding groups. An explanation for these findings is presented, based on the effect that births to high-parity women with low child mortality have upon the total neo-natal and post-neo-natal mortality rates. It was found that these births exhibit a much lower mortality risk than births to women of comparable parities and higher child mortality, and that their numbers account for the lower risk to the births in the oldest age group and largest family size. It was concluded that women with a combination of high parity and low child mortality most probably represent a group with superior socio-economic and or health conditions which contribute to the lower risk of neo-natal and post-neo-natal death.     

Demographic transition and economic growth: Empirical evidence from Greece

Over the past decades, due to a combination of declining fertility rates and rising life expectancies, most industrialized countries have experienced aging populations and low numbers of young populations that may pose economic problems in the future. This paper investigates the relationship first between fertility rate and infant mortality rate and second among demographic changes, real wages and real output in Greece over the period 1960–96. When we control for fluctuations in overall economic activity and the labor market on the bivariate relationship between fertility and mortality rates, the evidence suggests that Granger-causation must exist in at least one direction. The results show that in the long run a decrease in infant mortality rates, taking into consideration economic performance and the labor market, causes a reduction in fertility rates. Also, employing the vector error-correction models, the variance decomposition analysis and the impulse response functions, the empirical results support the endogeneity of fertility choice to infant mortality, the labor market and the growth process.

Bridging the gap: Determining long-term changes in infant mortality in pre-registration England and Wales

Much effort has been expended in analysing a small sample of parish registers to produce national estimates of infant mortality for the period 1570–1840. However, in an age when inter-parish variations in infant mortality were considerable, national trends often obscured local and regional differences. By analysing data from the initial years of Civil Registration (1839–1846) together with infant mortality rates from a range of parishes, it is possible to assess the extent of variation and change in England and Wales during the period 1580–1840. The geographical variations in infant mortality and the age structure of infant deaths were sufficient to suggest that the most important influence on whether infants survived was disease environments.
