Urbanization in Thailand, 1947–1967
Authors: Goldstein Sidney 
Published: March 2007

Abstract
Utilizing both census and population register data for the period 1947–1967, this analysis assesses changing levels and rates of urbanization in Thailand, compares regional variations in urbanization patterns, and relates such differences to selected indicators of economic and demographic development. Although the overall level of urbanization remains low, the rate of urbanization is high and the increase in the number of moderate sized urban places significant. Greater Bangkok, accounting for over half of Thailand’s urban population and almost two–thirds of all urban growth, has increased its primacy in Thailand’s urban structure. But urban development has also begun to permeate all regions of the country and to be an important factor in the complex process of national social and economic development.
Fertility trends in Australia
Authors: Spencer Geraldine M. 
Published: March 2007

Abstract
Using published data from the Australian vital registration and census systems, several time series are compiled: crude birth rates from the 1860s; fertility rates from the 1880s; age-specific and parity-specific measures from the 191Os; cumulative fertility measures by birth year of parent beginning with the 1890s; and cumulative fertility measures for marriages by year contracted from the 1910s.The decline in fertility to the 1930s, the upswing to 1961, and declines thereafter revealed by annual fertility measures show far more variation than do measures of total generation fertility—2.7 children per woman born in 1893–95, 2.3 1906–10, 2.8 1921–25, and perhaps 3.0 for women born in the 1930s. Both annual and generation measures show a younger age at parenthood, a decrease in childlessness, and progressively fewer large families. In the light of present experience, it seems not unreasonable to project generation fertility of 2.5 children, implying a crude birth rate of about 20 per thousand for the next fifteen years or so.
The prevalence of surgical sterilization in a suburban population
Authors: Phillips Nancy 
Published: March 2007

Abstract
This report presents data on the prevalence of tubal ligations, vasectomies and remedial sterilizing operations among white couples, with wife aged 20–54, who subscribe to a pre-paid medical care program and live in a suburban area near San Francisco. Contraceptive operations, more than two-thirds of which were male vasectomies, were found among 23 per cent of these couples. Some form of sterilizing surgery (contraceptive or remedial) was found among 31 per cent. The prevalence of surgical sterilization, specifically vasectomies, in this population is high compared with that found across the nation or in the Western states in the 1965 National Fertility Study. Variations in the prevalence of tubal ligations and vasectomies by parity, education and religion are described. Their prevalence increases with the parity of the wife, has a marked inverse relationship with education, and is highest when neither husband nor wife is Catholic.
Plans for the 1971 census of Canada
Authors: Beynon T. G. , Joshi G. B. , Pierre–Pierre F. K. 
Published: March 2007

Abstract
This article describes the plans which have been developed for the Census of Canada to be taken June 1, 1971. One of the most important features of this census will be the use of the Self-enumeration technique for the great majority of respondents. Other topics touched upon include the User Liaison Programme which established requirements, the Testing Programme which determined the methodology and some highlights of the Data Collection and Processing Phases of the operation. There is a brief discussion of the use of sampling in 1971 with particular emphasis on the benefits to be derived in increased quality and reliability of data, increased timeliness and reduction in respondent burden. The Quality Control procedures are described. The Post-censal Evaluation and Data Dissemination programmes are also dealt with.
An empirical study of the effects of socioeconomic development on fertility rates
Authors: Janowitz Barbara S. 
Published: March 2007

Abstract
Recent studies by Adelman and by Friedlander and Silver, which have investigated whether regression equations derived from cross-section data can be used to predict the impact of socioeconomic development on changing levels of fertility, are reviewed critically. Regression analyses based on data for 57 countries c. 1960 show that fertility (gross reproduction rate) varies cross-sectionally with region as well as with level of development (as measured by per capita income, percent labor force in primary sector, expectation of life, illiteracy rate). Using equations derived from the cross-section study and time-series data for five European countries during the period that their fertility rates fell, it is shown that predictions about past fertility changes are in error. The results suggest caution in the use of cross-section relations to predict the course of fertility in developing countries.
Estimation of contraceptive continuation functions
Authors: Kelly William J. 
Published: March 2007

Abstract
Evidence from Puerto Rico supports the hypothesis that the continuation rate has a decay form rather than a reciprocal form. As indicated in the literature, there was evidence that the continuation rate tends to vary not only with time but also with the age of the patient at acceptance. It was found that the fit of the continuation function could be improved substantially by making the effective decay rate an exponential function of age. Theoretical reasoning was presented to justify these empirical results.
A stochastic approach to the estimation of the prevalence of IUD: Example of Taiwan, Republic of China
Authors: Liu P. T. , Chow L. P. 
Published: March 2007

Abstract
Assuming three patterns of changes in number of new IUD insertions, three stochastic models have been developed for the estimation of the “prevalence” of IUD in situ at a given point of time. The advantages of these models, compared with the conventional ways of estimating IUD prevalence, rest with their ease of use and simplicity of method for calculating variances of the estimates. The models are also useful for family planning administrators to set program targets. A correction factor to estimate the number of IUDs which, although “currently in situ,” are worn by women who have “passed over” the upper age limit of their reproductive spans has also been developed. This is particularly useful in estimating the “effective retention” of IUD.
Residence background, socioeconomic status, and fertility
Authors: Ritchey P. Neal , Stokes C. Shannon 
Published: March 2007

Abstract
Previous research has demonstrated that socioeconomic differentials in fertility are heavily influenced by couples with rural background. These studies show an inverse relationship between fertility and socioeconomic status for couples of rural background, but no relationship for urbanorigin couples. The effect of urban background on rural fertility differentials has not been examined. This study investigates the potential effect of urban-origin couples on socioeconomic differences in fertility in rural areas. Data from the 1967 Survey of Economic Opportunity are analyzed to show that rural socioeconomic fertility differences are not influenced by the presence of persons of urban background.
Education, health and family size as determinants of labor market activity for the poor and nonpoor
Authors: Hill C. Russell 
Published: March 2007

Abstract
The effect of head’s and wife’s educational attainment, health and the number of the head’s dependents under 18 on the amount of time spent in the labor force by white and black male heads of both poor and nonpoor families is investigated in this paper. The technique employed is multivariate regression analysis using disaggregated data from the 1967 Survey of Economic Opportunity. While educational attainment has a positive effect on the supply of labor of nonpoor heads, it has an insignificant effect on the black poor and a nonlinear effect on white poor heads. The health of head and wife has a very important effect on the ability of the poor to supply labor services while for the nonpoor the health effect is insignificant. For both the poor and nonpoor, there is a positive relationship between family size and the supply of labor. Evidence is also presented to indicate that the black husband’s and wife’s labor market activity are substitutes while they are complementary within white families.
Interpersonal communication and the diffusion of family planning in West Malaysia
Authors: Palmore James A. , Hirsch Paul M. , bin Marzuki Ariffin 
Published: March 2007

Abstract
Using data from a 1966–1967 probability sample of West Malaysian married women 15–44 years of age, this paper analyzes the characteristics of women who were active in diffusing information about family planning. The woman’s age and her parity, her educational attainment, her race, her present residence (urban-rural), and whether or not she wanted more children were significantly related to opinion leadership in bivariate tables. However, these relationships appeared to be substantial mainly because these social and demographic characteristics were highly related to whether the woman participated in discussions about family planning with other women. Among women who did participate in such discussions, the social and demographic variables were not substantially related to opinion leadership. In fact, the critical variables for opinion leadership appeared to be participation in the discussions, greater knowledge of family planning, and a higher level of family planning use. An attempt is also made to assess the effect of interpersonal communication on the adoption of family planning among women in the sample.
Tobacco smoking and the sex mortality differential
Authors: Retherford Robert D. 
Published: March 2007

Abstract
This paper examines the effects of tobacco smoking on the sex mortality differential in the United States. It is found that all forms of smoking combined account for about 47 percent of the female-male difference in 50e37 (life expectancy between ages 37 and 87) in 1962,and about 75 percent of the increase in the female-male difference in 50e37over the period 1910–62. When these percentage effects of smoking are decomposed each into a sum of contributions by age and immediate medical cause of death, the degenerative diseases acting at the older ages are found to be of primary importance. The above results appear in large part to explain why the degenerative diseases also account for most of the 1910–65 increase in the female-male difference in life expectancy at birth. The analysis assumes that spurious effects due to the correlation of tobacco consumption with other mortality-related factors are small compared to the causal effects of tobacco consumption itself.
Residence background, migration, and fertility
Authors: Ritchey P. Neal , Stokes C. Shannon 
Published: March 2007

Abstract
This paper attempts to clarify confusion concerning residence background and migration, and to demonstrate that each of these factors exerts an independent effect on fertility. Basic premises underlying the direction of the effect of these variables on fertility are examined. Data from the 1967 Survey of Economic Opportunity indicate that migration and residence background do have independent effects. It is concluded that present generalizations as to the direction of their influence should be submitted to closer scrutiny with additional data in the future. In addition, an index of rural exposure is developed to test the proposition that fertility varies directly with degree of rural experience. The data only partially support this hypothesis. Moreover, rural-to-urban migrants are found to have only slightly higher fertility than the receiving urban-origin population.
Maximum likelihood estimates for the parameters of a continuous time model for first conception
Authors: Singh S. N. , Bhaduri T. 
Published: March 2007

Abstract
The duration of time between two successive births or between marriage and first birth is an indicator of the level of fertility of a couple. Potter and Parker (1964) and Singh (1961, 1967) have suggested the Type I Geometric as a distribution appropriate for representing the length of interval to first conception leading to a live birth. Potter and Parker estimated the parameters of this distribution with the help of the first two moments. Majumdar and Sheps (1970) pointed out the limitations of these moment estimates and gave a method to obtain maximum likelihood estimates, based on formulas which are too involved for solution without the help of a computer.
Singh proposed a continuous probability distribution based on another set of assumptions for the above situation. He outlined a method to obtain best asymptotically normal estimates of the parameters. These estimates are obtained after several iterations starting from any set of consistent estimates.
The objective of this paper is to show that it is relatively easier to obtain maximum likelihood estimates of the parameters of the continuous model, which describes the data on duration to first conception as well as does the discrete model. Simple expressions for the moment and maximum likelihood estimates with the corresponding covariance matrices are obtained. Application is made to three sets of data.
Determinants of male labor mobility
Authors: Pursell Donald E. 
Published: March 2007

Abstract
This study is concerned with male labor mobility in 84 urban labor markets. Mobility studies have frequently used employment variables to approximate differential labor demands and to explain mobility. It would seem that supply factors, as well as demand factors, could exert an influence on mobility. To assess the influence of supply factors, new labor force entrants and withdrawals, along with labor demand variables, were regressed against gross in- and out-migration rates.
The results confirmed the hypothesis that labor mobility is substantially influenced by the economic and demographic characteristics of the urban labor market. Higher rates of in-migration were found in regions with higher rates of new employment opportunities. Where the demographic characteristics of the labor market result in larger labor supplies, out-migration rates were found to be higher and in-migration rates lower. Labor seems quite sensitive to differential labor market conditions and would appear to flow toward markets where an economic advantage lies. One interesting interpretation of the negative association between in-migration and wages is that employment opportunities may expand more rapidly in low-wage sectors, perhaps in the nonmanufacturing sector, thereby providing job opportunities which attract labor into the region.
Impact of population changes on education cost
Authors: Arriaga Eduardo E. 
Published: March 2007

Abstract
This paper has two principal aims: (1) to analyze and measure how the demographic variables—mortality, fertility, and im migration—affect the cost of education; (2) to evaluate what possibilities developing countries, such as those of Latin America, have for a rapid educational improvement.
The paper relates demographic and educational variables of three different populations: Sweden, 1840–1965; the United States, 1850–1960; and Latin America, 1930–2000. Three educational variables are also considered: (a) school attendance rates by sex and age; (b) distribution of students of same age by grade; and (c) cost of student by grade.
Demographic changes in countries such as Sweden and the United States were favorable for the development of education. For the future, unless an increase of fertility occurs, mortality and fertility changes will not have a significant effect on the cost of education in these countries. In current less developed countries the demographic changes during the past were less favorable to educational development. A future reduction of fertility will significantly help them to achieve a higher educational level.
A systems model for the population renewal process
Authors: Bongaarts John P. , O'Neill William D. 
Published: March 2007

Abstract
A synthetic cohort of women is followed from birth through childbearing age. The transition from parity i to parity i + 1 is quantitatively described utilizing systems analysis theory. This description results in a parametrization of the renewal process in which the net maternity function is completely determined by five parameters: maturation time, 0th parity time constant, survival fraction to 0th parity, average child spacing time, and parity progression ratio. To detect trends in these parameters, estimates are made of them for the U. S. A. population from 1950 to 1965.
The interaction of migration, income, and employment in Sweden
Authors: Dahlberg Åke , Holmlund Bertil 
Published: March 2007

Abstract
A common approach in migration studies is to explain interregional migration by single-equation models. Such models are likely to suffer from simultaneous-equation bias when used in studies attempting to analyze migration over a long period of time. In this study, a simultaneous-equation approach is applied, which takes account of the interdependence between migration and income and employment changes. The four-equation model is estimated for 70 labor market areas in Sweden.
Fertility and land availability in rural Brazil
Authors: Merrick Thomas W. 
Published: March 2007

Abstract
Differences between the marital fertility of the agricultural frontier and that of the more settled rural areas of southern Brazil are analyzed in this paper. Fertility rates derived from 1970 census data appear to decrease as the degree of settlement increases, suggesting an experience parallel to the decline in U.S. rural fertility in the late nineteenth century, which Easterlin and others have attributed to increased scarcity of land for starting new farm households. Multivariate analysis of the Brazilian data shows parallels between the two situations but also reveals that the importance of literacy, child survival, and access to land is relatively greater than that of the availability of land for explaining fertility differentials in Brazil.
Contextual and ideological dimensions of attitudes toward discretionary abortion
Authors: Singh B. Krishna , Leahy Peter J. 
Published: March 2007

Abstract
This study examines the contextual and ideological dimensions of attitudes toward discretionary abortion using two national surveys. The abortion attitudes are dichotomized in terms of consistent opposition versus consistent support. Discriminant analysis, partial correlations, and stepwise regression procedures are used in the analysis. Findings indicate that education and attendance at religious services are the two most significant contextual dimensions and sexual permissiveness and fertility ideology are the two most significant ideological dimensions for explaining attitudes toward discretionary abortion. Implications of these findings are discussed.
An estimate of a rare population group: The U.S. Jewish population
Authors: Lazerwitz Bernard 
Published: March 2007

Abstract
High, middle, and low estimates for a rare population group, the Jewish population of the United States, are presented together with their root mean square errors. These estimates are based upon a national sample whose essential survey design features are outlined. The features indicate that difficult-to-find populations can be sampled in adequate numbers if some sort of a list can be developed with a fair proportion of the population. To this list must be added an integrated area sampl
Contraceptive sterilization in the U. S.: 1965 and 1970
Authors: Bumpass Larry L. , Presser Harriet B. 
Published: March 2007

Abstract
There was an impressive increase between 1965 and 1970 in the prevalence of contraceptive sterilization, an increase that accelerated in the later years of the period and was shared in by virtually all subgroups considered. Among couples in 1970 for whom sterilization had been an option (recognizing that it is a terminal method), about one of every five had chosen this method of contraception. About half of all sterilizations were vasectomies, though vasectomies have outnumbered tubal ligations in recent years. Differentials in prevalence and in increases during 1965–1970 are reported for a number of life-cycle and social variables. In addition, a profile of the contraceptive sterile is presented for recent sterilizations. Significant proportions are relatively young and of low parity at the time of sterilization. In the context of the continued diffusion of the pill and IUD and increases in legal abortion, the net demographic effect of increasing sterilization is regarded as low, though sterilization is an important component of an effective fertility control regime.
Asymptotic implications of fluctuating nuptiality and fertility considering both sexes together
Authors: Lee Che-Fu 
Published: March 2007

Abstract
In this paper we have suggested a procedure of measuring population change which takes into account fluctuating sequences of nuptiality and fertility schedules as they reflect a population’s response pattern to its changing socioeconomic conditions. Through numerical experiments, the two-sex population model of cyclical change, which considers the interaction between sexes through marriage, is seen to converge to an asymptotic stability. The advantage of such a convergence is to enable comparative investigations, in terms of a set of asymptotic parameters, of rather complex series of nuptiality and fertility changes and their implications for short-run oscillation in population structure as well as for long-run population growth.
The fallacy of the five million women: A re-estimate
Authors: Blake Judith , Das Gupta Prithwis 
Published: March 2007

Abstract
Explicit policy to control fertility in the United States to date has focussed on the “unmet need” for contraceptive services in 1966 among an estimated five million poor and near-poor women. This paper reestimates the number of women in need of contraceptive services by disaggregating (on the basis of tabulations from the Current Population Surveys for 1966 and 1967, and the 1965 National Fertility Study) all poor and near-poor women into 54 subgroups differentiated by age, marital status, religion, and color. Data from the 1965 National Fertility Study, and from other studies, are then used to estimate for each subgroup deductions for sterility, pregnancy, waiting time for conception, and negative attitudes toward and current use of contraception. The residual number of women who both want and require contraceptive services, but do not have them, is estimated to be 1.2 million, rather than 4.6 million. The fact that the re-estimate takes into account both existing contraceptive practice and negative attitudes toward family limitation accounts for much of the difference between it and the original figure.
