The japanese americans: Comparative occupational status, 1960 and 1950
Authors: Varon Barbara F.
Published: March 2007

En este trabajo se utilizan los datos de los censos de 1950 y 1960 sobre las distribuciones demográfica, educacional y ocupacional de los Japoneses-Americanos después de las migraciones obligadas de la Segunda Guerra Mundial, para comparar ellogro de los Japoneses-Americanos de las zonas urbanas con el de los blancos de las mismas zonas.

En primer lugar, los datos muestran que la poblacións J aponesa-Americana ha aumentado en todas las regiones del país, especialmente en el Oeste (de 71 porciento en 1950 a 82 porciento en 1960). En segundo lugar, el nivel educacional, que era más 0 menos igual al de los blancos en 1950, era mejor para el sexo masculino y aumentaba a una tasa más rápida 0 era mejor para el sexo femenino en 1960. En tercer lugar, mientras que en 1950 las diferencias entre las distribuciones ocupacionales de los Japoneses-Americanos y los blancos mostraron concentraciones desfavorables para toda la estructura ocupacional de los primeros, para 1960 los J aponeses-Americanos se habian acercadoa los niveles de la mayoría blanca.

De acuerdo a esto, los datos permiten al autor concluir que si “minoría” significa la exclusión completa de la vida de la sociedad, no puede llamarse minoría a los J aponeses-Americanos. En conclusión, el autor sugiere que sería útil investigar los patrones de miqración. de los Japoneses-Americanos, pues si la redisiribución ha dado como resultado la inieqración, tpromovera ésta una mayor mobilidad para conseguir una mejor integración?.
A reconsideration of negro-white mortality differentials in the United States
Authors: Demeny Paul , Gingrich Paul
Published: March 2007

Este trabajo resume los resultados de una investigacion sabre la validez de las dijcrcnciales de mortalidad entre blancos y neqros, como se preseniasi en las tables de vida oficiales desde el inicio del siglo.

En primer lugar, se ha derivado niveles de mortalidad y diferenciales por encima de la primera infancia sin usar los registros oiiales exisienies, mediante la interpretacion de series acumulativas de tasas de sobrevida dediez años, implicitas en los registros del censo, para nativos blancos y negros. Los resultados estan de acuerdo, en general, can las cifras oficiales, especialmente para hombres.

En segundo lugar, los niveles de mortalidad y diferenciales en la primera infancia se han esiimado extrapolando los valores oficiales e5 mediante tablas de vida modelos; esto es, por el procedimiento analitico que se seguiría en ausencia de información directa sobre la mortalidad en la primera infancia. A menos que se asuma que los patrones de mortalidad par edad para los Negros de Estados Unidos se desviaran extremadamente de aquellos encontrados en poblaeionee can censos y estadísticas vitales confiables, uno debe concluir que las cifras oficiales subestiman, en forma manifiesta, la mortalidad de Negros en la primera infancia, cuando menos para el período de 1910-40. Se deduce que durante esas décades; las diferenciales de mortalidad entre Negros y Blancos, en términos de expectativa de vida al momenta del nacimiento, fueron tambier: sustancialmente más altas de lo que surgieren las estimaciones oficiales.
On the momentum of population growth
Authors: Keyfitz Nathan
Published: March 2007

If age-specific birth rates drop immediately to the level of bare replacement the ultimate stationary number of a population will be given by (9): multiplied by the present number, where b is the birth rate, r the rate of increase, the expectation of life, and R0 the Net Reproduction Rate, all before the drop in fertility, and μ the mean age of childbearing afterwards. This expression is derived in the first place for females on the stable assumption; extension to both sexes is provided, and comparison with real populations shows the numerical error to be small where fertility has not yet started to drop. The result (9) tells how the lower limit of the ultimate population depends on parameters of the existing population, and for values typical of underdeveloped countries works out to about 1. 6. If a delay of 15 years occurs before the drop of the birth rate to replacement the population will multiply by over 2. 5 before attaining stationarity. The ultimate population actually reached will be higher insofar as death rates continue to improve. If stability cannot be assumed the ultimate stationary population is provided by the more general expression (7), which is still easier to calculate than a detailed projection.
The residential segregation of occupational groups in central cities and suburbs
Authors: Fine John , Glenn Norval D. , Kenneth Monts J.
Published: March 2007

The impression of journalists and social critics in the 1950’s that post-war suburbia was uniformly middle-class has been generally rejected by social scientists, but there is a persisting belief in a high degree of residential segregation by social level in suburbia and in a high degree of socio-economic homogeneity within suburban neighborhoods. A comparison of eight central cities with their suburban zones in 1950 and in 1960 revealed, for both dates, (a) small differences in occupational distributions between the central cities and the suburban zones and (b) generally higher Index of Residential Dissimilarity values for pairs of occupational groups in the central cities. These findings indicate that suburban neighborhoods, at least in the eight suburban zones studied, were little, if any, more occupationally homogeneous than the central city neighborhoods. This suggests that the belief in homogeneous suburban neighborhoods should be added to the growing list of discredited “myths of suburbia. ”
Vector representation of migration streams among selected state economic areas during 1955 to 1960
Authors: Tarver James D. , Gurley William R. , Skees Patrick M.
Published: March 2007

This paper uses in-migration, out-migration, and net migration vectors to measure and portray the migration streams occurring between April 1, 1955, and April 1, 1960, for all persons five years old and over on April 1, 1960, among 38 contiguous state economic areas (SEA’s) in Oklahoma, Colorado, Kansas, Missouri, Arkansas, Texas, and New Mexico. Both rectangular and polar coordinates were employed in computing three different types of vector representations. First, migration vectors for each SEA, expressed in total people-miles of in-movement, out-movement, and net movement represent the resultant direction of movement and the total people-miles of movement. Second, in- and out-migration vectors of the total people-miles of movement, with the widths of the vectors drawn proportional to the number of migrants, show the total size of each migration stream for each SEA, the resultant direction of movement, and the distance moved in total people-miles of movement. Third, in- and out-migration vectors of the average distances moved to and from each SEA, with the widths of the vectors drawn proportional to the number of migrants, show the magnitude of movement, the average distance moved per migrant, and the resultant direction of movement.

This study shows that migration vectors based upon polar coordinates are more accurate than the migration vectors based upon rectangular coordinates. Also, the in- and out-migration vectors are superior to net migration vectors in representing migratory streams among geographic areas.
Educational attainment as a selective factor in marital status transitions in the United States
Authors: Ortmeyer Carl E.
Published: March 2007

Data on marital status from the 1940, 1950, and 1960 censuses of the United States are organized to show (1) trends in percentages of men and women who were single, by age and education (grades of school completed); (2) relative education levels of husbands and wives for selected groups of couples in 1940 and I960 with comparisons for the two years; and (3) education levels of women in 1950 by marital status, controlling for age and year of entry into the 1950 marital status.

The rate at which single persons married for the first time increased markedly during the decade of the 1940’s but much less in the next decade. The 1940’s increases occurred for both sexes at all educational levels and at all ages except the oldest. However, the rate of increase was greatest for both sexes in the ages from about 20 to 34 for women and 22 to S4for men (modal age for first marriage is 18 for women and 21 for men). The distribution of percents single by age was about the same in all three censuses for persons with elementary schooling.

A trend toward smaller proportions of the single, both men and women, among young persons with college education continued for the entire twenty-year period, despite the lack of such a trend in the 1950’s at other age and education levels. However, the available data on education of first-married husbands and wives indicate that the ratio of college-educated husbands to college-educated wives was higher in 1960 than in 1940. Part of the explanation may lie in the relatively high proportions of college-educated women found in the marital statuses “divorced” and “married more than once” in the 1950 Census, particularly at the younger ages and shorter durations; but the data are not adequate for a very satisfactory explanation.

For the younger first-married for whom education of partners was cross-tabulated in 1940 and 1960, the proportions of college-educated persons were so much higher in 1960 than in 1940 that the proportions also increased of both husbands and wives at all educational levels who were married to college-educated partners. There was a marked decline in proportions of couples with only elementary schooling.

Finally, based on data from the 1950 Census for women (15–59 years of age), the separated group included more with only elementary schooling, as did the widowed. Those remaining single and those married once usually included the highest proportions of college-educated women.
Estimating marital fertility rates by educational attainment using a survey of new mothers
Authors: Sutton Gordon F. , Wunderlich Gooloo S.
Published: March 2007

Marital fertility rates by educational attainment of mother are estimated for the United States for 1963. These calculations are based upon information collected in a probability sample survey of women having births in 1963 and are prepared by relating birth estimates for educational attainment groups to estimates of married women in corresponding groups.

The rates do not display a negative association between educational attainment and the annual level of fertility, thus differing from the pattern observed in other measures of period fertility. Women who completed some high school but did not graduate and women with one or more years of college had higher annual fertility rates than women in other attainment classes.

Alternative estimation procedures are discussed which illustrate difficulties in obtaining satisfactory correspondence between two independent surveys which are used to obtain the rate calculation components.
Fertility and development in Brazil
Authors: Gendell Murray
Published: March 2007

In the past, one of the concomitants of development has been a sustained reduction in fertility. As a result of this experience, demographers hypothesize that in a society in which fertility is lower in urban areas, among the upper socioeconomic status groups and the better-educated, fertility will decline to a moderate level as the country changes from a rural, agricultural socioeconomic structure, with low levels of living and education, to an urban, industrial structure, with rising levels of living and education.

The data analyzed in this study indicate, however, that though substantial social and economic development (as measured by changes in industrial structure, per capita income, urbanization, and education) occurred in Brazil from at least 1920–40 to 1960, during which time fertility differentials of the kind indicated above existed, fertility has shown little or no tendency to decline. Between 1940 and 1960, in fact, the birth rate appears to have remained fairly constant around 43. With the death rate steadily dropping, the rate of natural increase and population growth (given a small net in-migration) has been accelerating.

From a theoretical point of view, these facts reinforce a growing realization, based on similar findings in some other developing countries, that the prevailing theoretical ideas concerning the relationship between development and fertility require modification, particularly in the direction of greater specificity. On the practical side, the question is raised whether Brazil’s rate of economic development during the postwar period up to 1960 can be maintained, let alone increased, in the face of a population growth rate which will probably average 3.2–3.5 percent for the period 1960–70 and which, in the absence of a decline in fertility, is likely to accelerate further.
Fertility of the jews
Authors: Goldscheider Calvin
Published: March 2007

The objectives of this paper were to review and summarize the existing literature on Jewish fertility and to discuss the highlights of data on fertility trends and differentials based on survey data obtained on the Jewish population of the metropolitan area of Providence, Rhode Island. The literature consistently confirmed the finding of lower fertility among Jews since the 1880’s in the United States and for the last seventy-five years in a variety of European countries.

A review of available data on fertility trends and differentials within the Jewish population indicated contradictory and inconsistent findings. The Providence survey data pointed to changing patterns of fertility among Jews and clarified a number of seeming inconsistencies. These data suggested (1) the pre-World War II decline and postwar recovery of Jewish fertility; (2) the change from an inverse relationship of social class and Jewish fertility among first-generation Jews to a direct relationship among second- and third-generation Jews; (3) the changing relationship of religiosity and Jewish fertility, which reflects social class changes.

Finally, an attempt is made to clarify the interpretation of these and related findings by placing the analysis of Jewish fertility in the context of assimilation and acculturation.
Female working roles and fertility
Authors: Stycos J. Mayone , Weller Robert H.
Published: March 2007

Using survey data gathered in Turkey in 1963, the relationship between female employment status and fertility is examined. Controlling for urban-rural residence, education, and exposure to conception within marriage, no differences in fertility by labor force status appear. Although there is a slightly greater tendency for employed than for non-employed women to hold attitudes more favorable to small families and family size limitation, the observed differences are slight and not significant statistically. A typology is constructed wherein the nature and causal direction of any existing relationship between female employment and fertility are predicted, based on the availability of birth control technology and the presence or absence of conflict between the roles of mother and worker.
Cultural complications in fertility interviewing
Authors: Choldin Harvey M. , Kahn A. Majeed , Ara B. Hosne
Published: March 2007

A description is presented of interviewing and other field work problems in a fertility and KAP survey among village women in East Pakistan. The female population studied had a very low literacy rate and no previous contact with social research.

In the survey described, village women were interviewed through the use of many standard questions concerning fertility and family planning. Inappropriate responses to these items were produced by the women. Many women misunderstood the questions or did not have the requisite information. This necessitated special explanations to respondents. One standard survey procedure which had to be modified in the field work was the maintenance of privacy in the interview situation.

Prior to the survey (which was done in conjunction with a pilot family planning project), an attempt was made to develop a corps of indigenous village data-collectors.
Vertical mobility and community type as factors in the migration of college graduates
Authors: Prehn John W.
Published: March 2007

Internal migration statistics are generally inadequate. One of the chief sources of this is the lack of direct data relating to migration. There appears also to be a lack of interest on the part of researchers in pursuing the study of the relationship between vertical mobility and migration. This study is designed to determine the relative importance of intergenerational vertical mobility and type of community or place of origin in contributing to the migration of college graduates by using direct mobility and migration data.

The study sample consists of 850 employed male graduates of eight private colleges in Iowa between 1954 and 1958. Data were obtained through the colleges and consist, among other things, of information about fathers’ occupations, graduates’ occupations, and the addresses of graduates both at matriculation and at the time of the study. Information about communities or places of origin is dichotomized on the basis of whether they are located in Standard Metropolitan Areas (SMA’s) in 1950 or whether they are located in non-SMA’s (NSMA’s). Upward mobility is treated as a product of higher education and as an antecedent of migration.

Hypotheses asserting the existence of associations between mobility and migration and between type of community or place of origin and migration are tested. Associations are established showing (1) that upwardly mobile graduates are more likely to migrate than others and (2) that graduates from NSMA’s are more likely to migrate than graduates from SMA’s.

The relative influence of the two factors is determined by partialing the associations between each factor and migration while holding the other factor constant. Type of community or place of origin is found to be of greater importance for migration than is upward mobility. Graduates from NSMA’s are more likely to migrate than those from SMA’s, regardless of their relative mobility. Graduates from SMA’s are likely to migrate only if they are also upwardly mobile.
Sample registration in India
Authors: Wells H. Bradley , Agrawal B. L.
Published: March 2007

India’s ad hoc sample registration scheme for obtaining current estimates of rural birth and death rates for the whole country is being implemented quite rapidly. Five states have 140 sample units, and eleven states will have from 20 to 100 units in the study depending upon the stage of implementation by March, 1967.

Essential elements of the project for each unit are: (1) continuous registration of vital events by a paid part-time local enumerator, (2) a six-month household survey to detect births and deaths which occurred during the previous six months, and (3) matching events from registration and surveys and field recheck of unmatched events to obtain the “best” count of real number of events. Preliminary results in a non-random sample indicate that the crude birth and death rates are around 37.1 and 15.7 per 1,000, respectively, for India’s rural population, but these probably will be found to be on the low side.

Most of the problems of implementation are operational or administrative rather than statistical: (1) For various reasons, some states are slow in agreeing to assume financial and other responsibilities for the scheme. (2) In many states, even after the scheme has been accepted, there are delays in recruiting the staff, training, and so forth. (3) The most serious problem in the whole project is maintaining control of field operations well enough at each stage to insure that prescribed instructions and methodology are being followed.

Experience in India indicates that staged implementation of such projects is highly desirable when trained staff are limited. There still are a number of methodological problems which must be tested as the sample registration evolves. Sample registration is one of the first steps in the Indian program to. develop an adequate vital statistics system. Exploratory studies to measure completeness of civil registration are being done now in an effort to develop means of using civil registration data alone for measurement of vital rates.

Differentials in divorce in maryland
Authors: Rosenwaike Ira
Published: March 2007

The basic data needed for measurement of the risks of termination of the legal relationship of marriage by characteristics of the marital partners are not available at this time for the United States because the national divorce registration area includes less than half the States. Special studies based on selected census data or the records of marriages and divorces occurring in one State or community have provided much of the valuable but limited information at hand. Statistics for individual States are subject to substantial bias as a consequence of inter-State migration between time of marriage and time of divorce, but they must serve as a basic data source until national reporting has improved. A record linkage study was undertaken which tied marriages occurring in the State of Maryland in 1959 with divorces occurring in the State in the years 1959–66. Relative, not actual, divorce risks by race, age at marriage, and previous marital status were calculated for couples with at least one partner an in-State resident at the time of marriage. The dissolution rate was higher for whites than for nonwhites. Marriages contracted by persons at very youthful ages and by persons who had been married previously were found subject to greater than average risks of dissolution through divorce.
Correlates of divorce in the U.S.S.R.
Authors: Mazur Denis Peter
Published: March 2007

The theoretical rationale of this study is that conditions associated with divorce reside outside the family within a broader social system where the family finds itself located. The absence of major differences in divorce law from one place to another within the Soviet Union makes it possible to explore this hypothesis by examining areal differentials in divorce rates. Crude divorce rates and crude marriage rates for 1960 have been published in Vestnik Statistiki for 109 political-administrative areas in the Soviet Union. Several indicators of modernization are available for the same areas from the 1959 U.S.S.R. Census of Population. About 80 per cent of the variation among areas with respect to the crude divorce rate is accounted for by six variables: the crude marriage rate, the percentage of urban population, and the employee-worker ratio in the labor force, each of which is positively associated with the divorce rate; and the proportion of poorly educated women, the ratio of children to adult males, and the mean household-family size, each of which is negatively associated with the divorce rate.
Migration between India and Pakistan, 1951–61
Authors: Visaria Pravin M.
Published: March 2007

A critical evaluation of the available data on migration between India and Pakistan in the 1951–61 decade leads to the conclusion that there was a substantial net migration of Pakistan-born persons into India, but only a negligible net migration of India-born persons into Pakistan. Annual administrative statistics published by the Indian Government suggest an immigration from Pakistan of the order of 1.16 to 1.32 million. More importantly, birthplace data from the Indian censuses indicate a net intercensal immigration of Pakistan-born persons amounting to 1.19 to 1.34 million, depending on the assumed level of mortality. The Pakistani census data on the India-born show no net influx from India during 1951–61. Intercensal growth rates for the populations of different religious faiths in Pakistan are consistent with the estimates of net immigration into India. The migrants and the survivors of their progeny are estimated to represent a net gain of about 1.68 million by India and to account for no more than 2.2 per cent of the total population growth in India during 1951–61.
Two measures of geographic location and their relation to income
Authors: Morgan James N. , Sirageldin Ismail
Published: March 2007

Two different ways of categorizing people’s geographical location are compared as to their relation to earned incomes of family heads, after adjustment for education, age, sex and race. One, the traditional code, uses the size of the city in which the family lives. The other, originally suggested by Bernard Lazerwitz, focuses on the distance to, and the size of, the central city of the nearest standard metropolitan statistical area. Both appear useful, and their joint effects are examined.
Family composition and the labor force activity of American wives
Authors: Sweet James A.
Published: March 2007

This is a study of the employment patterns of American wives in relation to the composition of their families. The data are taken from the 1960 United States Census, both from published tabulations and the 1/1000 sample. The population studied is non-Negro, non-farm, married, husband present women who are under the age of sixty. The methods of analysis used include the comparison of employment rates among subpopulations and a dummy variable regression technique. Aspects of family composition studied include age of the youngest child (in single years in order to determine whether there are discontinuities in the rates of employment when youngest children enter school, etc.), number of children in the family, and the presence of other relatives in the family. The paper concludes with a discussion of the meaning of family status differentials in employment including differential preferences for employment, differential fertility experience, and differential demands on the mother’s time. Some discussion of the use of cross section data of this sort to infer life cycle patterns of employment is included.
Family planning and population control in developing countries
Authors: Raulet Harry M.
Published: March 2007

This essay aims at a critical analysis of the major assumptions of the family planning movement and their implications for population and development policy in the less developed countries. A neo-Malthusian perspective, in which a reduction of the current high rates of population growth is considered to be a necessary condition for economic development in the less developed countries, is dominant among professionals in family planning. Population control has come to be regarded as a kind of“leading sector” in the development process. The position taken in this paper is that the contention that fertility reduction is crucial to short term economic development is not substantiated empirically and represents a distorted view of the economic development process. Nor is there good evidence that demographic modernization can move far ahead of other aspects of modernization. Skepticism about the success of family planning tends to lead to advocacy of alternative methods of population control which are generally beyond the economic, administrative, and political capacities of the less developed countries and are sometimes repressive in tone. The family planning movement, in overstressing the independent contributions of fertility reduction programs, has tended to underplay conditions such as improved health, lowered mortality, and altered opportunity structure which make these contributions possible at all.
Labor force participation and family formation: A study of working mothers
Authors: Theodore Groat H. , Workman Randy L. , Neal Arthur G.
Published: March 2007

Drawing upon a sample of 638 mothers aged 18 to 40, with at least some marital work experience, significant associations were found between the extent, kind, and timing of employment and a series of family formation variables. Generally lower fertility, longer first birth intervals, and earlier use of birth control were associated with the longest work durations, the highest status jobs, and work before the birth of the first child. The data failed, however, to differentiate desired family size.
Legal Abortion and Fertility in Maryland, 1960–1971
Authors: Rosenwaike Ira , Melton Robert J.
Published: March 2007

In the brief period between 1967 and 1971 about one-third of the state legislatures passed abortion reform bills, and in states such as Maryland the number of legal abortions soared. Maryland with its good reporting system for legal abortions, as well as its demographic representativeness, appears to offer an ideal “test situation” for assessing the impact on fertility of the new liberalization. Data on live births and reported induced abortions to residents of the state have been compiled and analyzed in an effort to interpret the recent changes in birth rates. Variables examined include maternal age, birth order, race, and legitimacy.

Since 1968, Maryland, along with higher than national average abortion ratios, has experienced a rate of decline in fertility greater than that for the nation. In addition, most of the age and parity groups with high abortion ratios show fertility declines greater than those for groups not using abortion as extensively, Nevertheless, because a number of different factors simultaneously influence fertility, it is hazardous to make accurate cause-and-effect statements on the relationship of any single one of these to the observed change.
Economic Development and Fertility Change in Mexico, 1950–1970
Authors: Hicks W. Whitney
Published: March 2007

This paper is an attempt to isolate the determinants of fertility in Mexico. Of the variables included, two are significant in accounting for differences in the level of completed fertility in the 32 “states” in 1970. They are the share of the labor force in agriculture, which is directly related to fertility, and the percentage of the population speaking an indigenous language, which shows an inverse relationship.

The most important factors acting to reduce total fertility rates over time are increases in life expectancy and declines in the share of the labor force in agriculture. However, based on the estimated linear relationship, these two variables by themselves are not adequate to achieve a rapid decline in fertility in the future.
Modeling and Forecasting Populations by Time Series: The Swedish Case
Authors: Saboia Joao L. M.
Published: March 2007

Time series analysis techniques are used to model and to forecast populations. An autoregressive (AR) and a moving average (MA) model, which seem to fit the population of Sweden very well, are found. Forecasts are calculated using both models and are compared with the forecasts obtained by other methods. This comparison is very favorable for the time series models. Although our study is confined to the mid-year population of Sweden, there are good reasons to expect that the technique can be successfully applied to other population parameters.
The Social Ecology of Madrid: Stratification in Comparative Perspective
Authors: Abrahamson Mark , Johnson Paul
Published: March 2007

This paper examines the characteristics of residential zones in Madrid, Spain. The primary difference between zones is found to lie in a new bourgeoisie life-style dimension. Working women are found to be the best indicator of this dimension, which also involves servants, natives of Madrid and high degrees of literacy. Fertility-related considerations, however, are unrelated to working women, and this is explained as due to the availability of domestic help and “women-oriented” working arrangements. Fertility and socioeconomic status are found to be interrelated and constitute a second dimension of residential segregation. In conclusion, Madrid is examined in relation to both more and less industrialized cities, leading to a further modification of social area theory contentions concerning the ecology of stratification in developing cities.
Marital instability and the economic status of women
Authors: Hoffman Saul
Published: March 2007

This paper uses longitudinal data from the Panel Study of Income Dynamics to examine the relationship between changes in marital status and economic status. Differences between men and women and between whites and blacks are also considered. A major finding is that, after adjusting for changes in family size, the economic status of divorced or separated men improves, while that of women declines. Components of income change are discussed, with special emphasis on changes in the labor force and welfare status of women who were divorced or separated during the analysis period. Finally, data on the magnitude and distribution of alimony/child-support payments are presented.
The Formal Dynamics of Controlled Populations and the Echo, the Boom and the Bust
Authors: Lee Ronald
Published: March 2007

This paper analyzes the pattern of fluctuations of births in an age-structured population whose growth is subject to environmental or economic constraint. It synthesizes the traditional demographic analysis of age-structured renewal with constant vital rates and the economic analysis which treats population change endogenously. When cohort fertility depends on relative cohort size, or when period fertility depends on labor force size, fluctuations of forty or more years replace the traditional “echo” or generation-length cycle. Twentieth-century U. S. fertility change agrees well with the theory, as the “Easterlin Hypothesis” suggests; but the period model fits better than the cohort model.
The Measurement of Family Size Preferences and Subsequent Fertility
Authors: Coombs Lolagene C.
Published: March 2007

A new method for measuring preferences for number of children is presented and related to the subsequent fertility of a panel of married women over a five-year period. TheI-scales, developed on the basis of unfolding theory, reflect the individual’s utility function for children. They differ from global stated preferences and are more fine-grained measures, sensitive to variations from a first choice. Scales obtained at an initial interview were found to be consistently predictive of fertility in the prospective period, net of a number of other variables usually associated with differential fertility. Their potential both as independent and dependent variables in research is discussed.
Natural Population Decrease in Iowa Counties
Authors: Chang H. C.
Published: March 2007

As a follow-up on the studies by Dorn and Beale, this paper examines differences between Iowa counties with natural decrease and those with natural increase and analyzes the part that migration and fertility played in bringing about an excess of deaths over births in Iowa counties. The county groups are distinctly different in demographic and socioeconomic characteristics. Out-migration as a mode of response adopted by the rural population in Iowa is by far the most dominant factor leading to natural decrease. Sustained net out-migration is more likely to touch off natural decrease in counties of comparatively low fertility than in those with higher fertility. Low fertility is, therefore, a contributing factor to the imbalance between births and deaths, but the amount of influence of fertility adjustment over the fertility differentials among county groups cannot be ascertained in this study because of the correlation between fertility and Catholic Church membership in counties. The data of this study were obtained from the population censuses and vital statistics.
Annexation as a factor in the growth of U.S. cities, 1950–1960 and 1960–1970
Authors: Klaff Vivian Z. , Fuguitt Glenn V.
Published: March 2007

The incidence of annexation, the growth in the original area and in the area annexed, and the proportion of growth due to annexation between 1950 and 1970 are analyzed for U.S. cities grouped by size, metropolitan status, and region of the country. Over this period, annexation was a principal means of population growth for incorporated places outside the Northeast. Though often associated with metropolitan growth, annexation was even more important in the growth of nonmetropolitan cities. Overall growth differences by size of place, metropolitan status, and decade (1950–1960 or 1960–1970) could not be explained by the incidence and nature of annexation.
Is Nonmetropolitan America being repopulated? The evidence from Pennsylvania’s minor civil divisions
Authors: Zelinsky Wilbur
Published: March 2007

We analyze population change and net migration, by age and sex, from 1940 to 1970, for 1,834 Nonmetropolitan Pennsylvania Minor Civil Divisions (MCD’s) classified by residence, population potential, socioeconomic status, and distance from metropolitan centers. Our analysis indicates, as expected, reconcentration of residents from both urban and remoter nonmetropolitan localities into exurban peripheries 25 to 35 miles from metropolitan centers. Since 1960, however, a “turnaround” appears in many truly rural tracts, which have been experiencing an influx or retention of persons 35 years of age and older. Statistical explanations are strongest for males in poor, isolated places, weakest for more accessible, socioeconomically advanced places and their female inhabitants. Throughout the study period and area, nonurban MCD’s register more positively than the rural.
Effects of various factors on selection for family planning status and natural fecundability: A simulation study
Authors: Barrett John C.
Published: March 2007

The effect of various factors on selection for family planning status and for natural fecund ability is studied in a simulation that incorporates a beta distribution of fecundability among women. The mean fecundabilities of current spacers, current limiters, current nonusers, and pregnant women are compared. These ratios are influenced by duration of marriage and by desired number of children. Effects of different levels of contraception are measured. Another strategy, spacing the last two wanted births, is also studied. It is found that breast-feeding status has little effect on fecundability selection. The women usually found to have greatest fecundability are not those recently pregnant at durations of marriage five and ten years, unless they wanted fewer than two children, but rather those who are using contraception to limit the number of children.
Influence of instantaneous fertility decline to replacement level on population growth: An alternative model
Authors: Mitra S.
Published: March 2007

If age-specific birth rates m, of a stable population drop abruptly tomx/R0, whereR0 is the net reproduction rate, then, according to Keyfitz, the size of the ultimate stationary population relative to.that at the beginning of the process is given byI =be00R0 − 1)/(rμR0, whereb andr are the birth rate and the rate of growth, respectively, of the stable population,e00 the life expectancy at birth, andμ the average age at childbirth in the resulting stationary population. Noting that the decline inmx need not necessarily be uniform, investigation has been carried out to examine the effect on Iwhen fertility decline is more rapid at higher ages. In particular, the effect of the reduced age-specific rates such asmxe−rx (which also produces a stationary population) has been analyzed, and simplifications of the results carried out separately for three different models of the net maternity function. It has also been shown that when m, drops abruptly to somemx*, where the form ofmx* need not be specified except for the restriction that the resulting population will be stationary, the value of the index can be approximately obtained fromI* =be00 (1 -rμ/2), whereμ is the average age at childbearing of the initial stable population.
Sensitivity analysis of discrete-time interregional population systems
Authors: Liaw Kao-Lee
Published: March 2007

This paper shows analytically how (a) the long-run growth rate and (b) the long-run proportional distribution of an interregional population system with a time-homogeneous structural matrix are affected by small changes or errors in (a) the natural growth rates of individual regions and (b) the interregional migration rates. Furthermore, the analytic results are applied to an eight-region Canadian population system. Finally, it is claimed that the method introduced here can be easily applied to sensitivity analysis of both the intrinsic growth rate and the “stable” age-composition of the Leslie model with respect to changes in age-specific birth and survival rates.
Race and intra-urban migration
Authors: Freeman Linton C. , Sunshine Morris H.
Published: March 2007

Data from the urban renewal experience in Syracuse, New York are used to examine the impact of race on patterns of intra-urban migration. The results show that, overall, the migration patterns exhibited an exponential decay in frequency with increasing distance. Both blacks and whites display this pattern, but blacks tend to cluster more closely around the point of origin. Indirect evidence is developed to show that this phenomenon is due to blacks and whites having different access to information about housing, which ultimately maintains housing segregation.
The effects of demographic factors, family background, and early job achievement on age at marriage
Authors: Hogan Dennis P.
Published: March 2007

National data for ever-married men aged 20 to 65 in March 1973 are utilized to estimate least squares and log-linear structural equation models of age at marriage. We demonstrate that most characteristics of family background (including both the family structure and its socioeconomic standing) are irrelevant in their effect on age at marriage. Intercohort trends are not explicable with reference to the changing socioeconomic, ethnic, or nativity compositions of the cohorts. Regional differences in age at marriage have persisted over the years in only slightly diminished form and cannot be explained by reference to the nativity, ethnic, or socioeconomic compositions of the regions. Early job status relates only weakly to age at marriage. Only those activities that are time-consuming or otherwise disruptive of the smooth operation of normal life-cycle processes during the transition from adolescence to adulthood (such as college attendance and service in the military) seriously affect the age at which a man marries.
The urban distribution of headquarters and branch plants in manufacturing: Mechanisms of metropolitan dominance
Authors: Lincoln James R.
Published: March 2007

The proposition that ties between home offices and branch plants constitute a form of metropolitan dominance is evaluated by examining the dependence of these two forms of manufacturing organization on selected characteristics of the 110 largest SMSAs. The predictor variables in the analysis are measures of industry composition, population size, and regional location, factors which past research has shown to be indicators of rank in an urban hierarchy of dominance. The data generally support the hypothesis in revealing that headquarters locate in large, diversified urban areas, whereas branch plant employment is highest in small, economically specialized places. Both headquarters and branch plant activity proved to be associated with the percent of the SMSA labor force employed in manufacturing, however. The suggestion drawn from earlier studies, that specialization in metropolitan financial-commercial functions should be related to the headquarters’ presence, receives only mixed and ambiguous support in this investigation.
Estimating demographic characteristics using the ratio-correlation method
Authors: Martin Julia H. , Serow William J.
Published: March 2007

Studies of the relative accuracy of methods of estimating the population at the substate level have generally found that the greatest degree of accuracy is provided by the ratio-correlation, or regression, method. This paper reports on research aimed at evaluating the effectiveness of this method in estimating the age and race composition of populations at the substate level. In addition to the basic multiple regression equation, variants such as stratification and the averaging of estimates from simple regression equations are also tested. Surprisingly, for Virginia localities the most satisfactory results are generated by the nonstratified multiple regression equation.
The relation of psychological, social, and economic variables to fertility-related decisions
Authors: Jaccard James J. , Davidson Andrew R.
Published: March 2007

To test a recent model of social behavior, a questionnaire was designed and administered to 270 married women in a midwestern city. A stratified random sample was obtained, comprising a 2 × 3 factorial design (Catholic vs. Protestant and high vs. middle vs. low socioeconomic status). It was hypothesized that an individual’s intention to engage in a fertility-related behavior would be highly correlated with (a) her beliefs about the consequences of performing that behavior weighted by the value of those consequences, and/or (b) her beliefs about what relevant others think she should do and her motivation to comply with those others. The data strongly supported this hypothesis for each of three different behaviors. Analysis of variance revealed a significant religious differential for intentions to have a two-child family (Catholics were less likely to intend to have a two-child family than Protestants). This differential was further examined in terms of the proposed model of behavior.
Net immigration of gainful workers into the united states, 1870–1930
Authors: Schachter Joseph
Published: March 2007

This paper presents a socioeconomic occupational grouping of the foreign-born gainful workers of the United States at each census from 1870 through 1930. This series is then used to estimate the net immigration of gainful workers into the United States during each of the six decades from 1870 to 1930 cross classified by occupational group and sex. The following three conclusions are then drawn from the above two series.

First, the socioeconomic position of the foreign-born population of the United States remained relatively stable from 1870 to 1910 but then increased appreciably from 1910 to 1930. Second, although most of the contribution that immigration made to the United States labor force was in the form of semiskilled and unskilled workers, the relative importance of professional, clerical, and skilled workers increased almost continuously from 1870 to 1930. Third, the “new immigration” was not less skilled than the “old immigration”. On the contrary it was actually more skilled than the “old immigration”.
