A Gompertz fit that fits: Applications to canadian fertility patterns
Authors: Murphy Edmund M. , Nagnur Dhruva N. 
Published: March 2007

Abstract
In this paper an attempt is made to refine the method of fitting the Gompertz function to the cumulative fertility rates by using iterative techniques. The method is tested with the historical data series for the Canadian population. The demographic implication of the parameters of the Gompertz function as fitted to the fertility distribution is examined, and the usefulness of the method in projecting future fertility trends is studied. The Makeham function is also fitted to the fertility distribution by the same iterative technique, and the relative efficiency of this function is compared with that of the Gompertz.
Evaluation of family planning program performance: A critical review
Authors: Reynolds Jack 
Published: March 2007

Abstract
Family Planning Program Evaluation is not a well-developed art, much less an exact science. The evaluation of the performance of such programs has received a good deal of attention but the methodologies are still controversial and the results inconclusive. This is due to a wide variety of constraints, not all of which are technical, and most of which are not unique to family planning. The prospects for improvement of FPPE depend, to a great extent, on overcoming these constraints.
Factorial ecology: A critique and some suggestions
Authors: Hunter Alfred A. 
Published: March 2007

Abstract
Studies in factorial ecology have typically used the principal factor procedure coupled with varimax rotation. Since it can be shown that the results one obtains vary according to the factor and rotation models he employs, and since there is no one “best” way of obtaining initial and derived factor solutions, it is proposed that future research in the area adopt an approach involving the simultaneous use of several different computing algorithms for obtaining initial solutions and both orthogonal and oblique rotation procedures to avoid the possibility that the results one obtains are not method-dependent. Ideally, the factor models employed should differ maximally with respect to the principles upon which they are based. If one finds a given factor regardless of the method he uses, only then can he assert with any confidencethat it is not an artifact of his method. Factorial ecologists are often interested in computing “factor scores”, but “true” factor scores are not uniquely computable; they can only be estimated. Since the proposed research strategy involves using either a component or an image model, in which the corresponding scores are exact and uniquely computable, the factor score problem is, in a sense, solved. Next it is suggested that, by using orthogonal solutions, factorial ecologists may be overlooking a very important piece of information—the correlation between the factors. There is some reason to believe that this varies from city to city, and may account for the fact that some factors which emerge in studies of Western cities are sometimes not found in cities elsewhere. Some comments are also made on the value of using census tract data, and on the availability of computer programs for different initial and derived factor solutions.
Demographic correlates of group achievement: contrasting patterns of Mexican-Americans and Japanese-Americans
Authors: Uhlenberg Peter 
Published: March 2007

Abstract
Patterns of family size, family stability, and timing of family formation characteristic of Mexican-Americans are contrasted with those of Japanese-Americans, and consequences of their demographic differences for group achievement are explored. Mexican-Americans are found to have a demographic system marked by young ages at marriage, young ages at beginning of childbearing, high rates of reproduction, and high rates of marital instability. Japanese-Americans display just the opposite pattern of behavior on each of these variables. Using existing research on determinants of individual achievement, reasons are then suggested why the demographic environment encountered by Japanese-American youth is more conducive to educational and economic achievement than is that encountered by Mexican-American youth.
Factors associated with religious and civil marriages
Authors: Rosenwaike Ira 
Published: March 2007

Abstract
Religious preference and educational level appear to be the major characteristics accounting for variation by age at marriage among Americans. Differences in age at marriage by educational attainment have been definitively documented in census reports, while those by religion have been based largely on analyses of the experience in the two states where religion is a separate item on the marriage certificate. This current study of category of ceremony data, as reported on marriage certificates, indicates that this item can, for some purposes, fairly adequately serve as a substitute source of data for specific religious information. Data for Maryland residents, showing that persons involved in Jewish and Catholic weddings marry later than those in Protestant ceremonies, are in close agreement with findings obtained in a national probability sample which ascertained religious preference and age at marriage.
Fertility, life cycle stage and female labor Force participation in Rhode Island: A retrospective overview
Authors: Mott Frank L. 
Published: March 2007

Abstract
Considerable historical evidence indicates a long term increase in female labor force participation in the United States during the twentieth century. However, there are only limited data available for analyzing this secular trend in any depth. Comprehensive retrospective data for a representative sample of 1,578 once-married Rhode Island women are utilized to examine the changing historical relationships between female work participation in selected life cycle intervals and educatonal attainment. The data indicate that there has been a recent convergence of labor force rates between better and less educated women, in some instances reversing the traditional pattern of higher labor force rates for less educated women. This convergence reflects primarily an extraordinary in-crease in labor force participation for women with at least twelve years of school at all stages of the childbearing period. Also highlighted is the close relationship between labor force participation in one life cycle interval and probability of participation in subsequent intervals. It is found that working or not working in one life cycle is a useful predictor of subsequent work participation. Also, a greater tendency for more recent cohorts of women to re-enter the labor force after childbearing is noted.
Effect on Unwanted Fertility of Extending Physician-Administered Birth Control in the United States
Authors: Udry J. Richard , Bauman Karl E. 
Published: March 2007

Abstract
A goal of publicly subsidized family planning programs in the United States is to prevent unwanted births, and the primary means being used to achieve this goal is to increase coverage with physician-administered contraception, with priority being given to persons from low-income families. We analyzed data from families living in low-income neighborhoods to determine whether that means would contribute to that goal, and if so, how much unwanted fertility might be decreased through increased coverage with physician-administered methods.
The results indicate that increased coverage with those methods would decrease unwanted fertility by 80 percent (79 percent among blacks, 83 percent among whites). Increasing the ratio of sterilization to pill and IUD makes the effect of the increased coverage even more dramatic.
The Bogue-Palmore Technique for Estimating Direct Fertility Measures From Indirect Indicators as applied to Tennessee Counties, 1960 and 1970
Authors: Tuchfeld Barry S. , Guess Leverett L. , Hastings Donald W. 
Published: March 2007

Abstract
Bogue and Palmore’s technique for estimating direct fertility measures from indirect indicators IS applied to the 95 counties of Tennessee 1960 and 1970. Findings based on these data tentatively suggest that this technique may be better suited for cross-national research than for analysis of small population units. It is recommended that the “own child” method is more appropriate for estimating fertility when utilizing data on counties.
Pregnancy Termination Intervals in a Rural Area of Bangladesh
Authors: Stoeckel John , Choudhury A. K. M. Alauddin 
Published: March 2007

Abstract
Pregnancy termination intervals, i.e., live birth to live birth (LB-LB), live birth to fetal loss (LB-FL), and fetal loss to live birth (FL-LB), are analyzed prospectively between 1966 and 1970 in a rural population (117,000) of Bangladesh. Results indicate that the mean LB-LB interval was almost 30 months, the LB-FL interval 27 months, and the FL-LB interval 18 months. In addition, postpartum amenorrhea was estimated to be about 13-14 months, and the time added by a fetal loss toa LB-LB interval about 15 months. No relationship was found between LB-LB intervals and the number of living or dead children.
White-Nonwhite Differentials in Occupational Mobility among Men in the United States, 1962–1972
Authors: Hauser Robert M. , Featherman David L. 
Published: March 2007

Abstract
Intercohort shifts between 1962 and 1972 in the occupation distributions of white and nonwhite men are analyzed and compared at ages 35–44, 45–54, and 55–64. Both white and nonwhite occupation distributions were upgraded over the decade, but among nonwhites the shifts away from the lowest-status occupations were expressed partly in increasing rates of absence from the labor force. There are indications of especially rapid shifts in the occupation distributions of nonwhite men at ages 35–44. Among whites and nonwhites intercohort shifts in the occupation distribution can be attributed primarily to changing patterns of movement from first full-time civilian jobs to current occupations, rather than to changing occupational origin distributions or patterns of movement to first jobs. The white and nonwhite occupation distributions did not show a clear pattern of convergence over the decade. They became less similar at ages 35–44 and more similar at older ages. White and nonwhite distributions were most likely to converge in those occupation groups where the share of whites was stable or declining, rather than in groups whose share of the occupation distribution was increasing. Later cohorts of nonwhites would have a much more favorable occupational distribution if they had enjoyed the mobility patterns of whites in earlier cohorts. In 1972, as in 1962, the inferior occupational chances of nonwhites are due primarily to their disadvantageous patterns of occupational mobility, rather than to impoverished social origins.
The Marriage Squeeze
Authors: Muhsam H. V. 
Published: March 2007

Abstract
If the sex-age structure of the population is equilibrated, observed marriage patterns are assumed to reflect preferred mate selections. With regard to age, these preferences can be expressed in terms of the probabilities of unmarried persons of given ages marrying persons of various ages. To study the situation of unequilibrated sexes, these probabilities can be used to compute, for each combination of ages of groom and bride, the expected number of grooms and the expected number of brides. If either of these numbers exceeds the other, the corresponding sex is in a “marriage squeeze.” The comparison among the expected number of grooms, that of brides, and the observed number of marriages supplies information on the effects of the squeeze.
In Australia, marriage statistics of 1949 were considered to reflect preferred selections. In 1958, men of most ages were in a squeeze. As a consequence, some relatively younger and older men did not get married, and some relatively younger and older women improved their chances of marriage in the year under consideration. 291–299
New Estimates of the Vital Rates of the United States Black Population During the Nineteenth Century
Authors: Eblen Jack Ericson 
Published: March 2007

Abstract
The difficulties of obtaining credible estimates of vital rates for the black population throughout the entire nineteenth century are overcome in this study. The methodology employed the notion of deviating networks of mortality rates for each general mortality level, which was taken from the United Nations studyThe Concept of a Stable Population. Period life tables and vital rates for intercensal periods were generated from the new estimates of the black population at each census date. The results of this study are highly compatible both with the life tables for the death-registration states in the twentieth century and the recent Coale and Rives reconstruction for the period from 1880 to 1970 and with several estimates of vital rates previously made for the mid-nineteenth century. This study places the mean life expectancy at birth for the black population during the nineteenth century at about 33.7 years for both sexes. The infant death rate (1000m0) is shown to have varied between 222 and 237 for females and between 266 and 278 for males. The intrinsic crude death rate centered on 30.4 per thousand during the century, while the birth rate declined from 53.2 early in the century to about 43.8 at the end.
Residential preferences and migration
Authors: De Jong Gordon F. 
Published: March 2007

Abstract
For some time now, public opinion polls have revealed Americans’ strong preference to live in comparatively small cities, towns, and rural areas rather than in large cities. However, as Fuguitt and Zuiches (1975) have reported, the majority of people also want these places to be within commuting distance of a large metropolitan city. This research tests the hypothesis that size-of-place and urban proximity preferences are factors in the dispersal of population through migration. A one-year panel survey of Pennsylvania households indicates that only about one household in ten that moved actually attained its preference for a smaller-sized place or a location more distant from a large city. Preferences for smaller-sized places and proximity to a city were not correlated with where people actually moved when the size and proximity of the previous residence were taken into consideration.
Relative income and fertility
Authors: Choudhury Rafiqul Hudo 
Published: March 2007

Abstract
The present study examines the relationship between relative income (i.e., actual income in relation to the expected income of one’s socioeconomic group) and fertility, using data collected by the 1967-1968Canadian Family Growth Study (Balakrishnan et al., 1975). We broaden the tests of relative income beyond cumulative fertility to spacing behavior and then examine some of the assumptions included in the relative income model of fertility. Results of the tests, in brief, are as follows: (a) Relative income is found to be more closely related to spacing than to cumulative fertility; and (b) the relationship between relative income and fertility is strongest among those couples who plan their life ahead and have a high level of education and occupation, and when temporal alignment is brought between the measures of relative income and fertility. For the relative income model to receive confirmation, it was specified that the following hypotheses must be confirmed: (a) that fertility behavior would vary positively with relative income but the fertility norm would show no relationship with relative income; and (b) that consumption norms and behavior would show no relationship with relative income. The outcome of these tests are in the expected direction, giving support to the relative income model. In addition, there is some evidence of predictive capability of the relative income model for correlative behavior.
Mother’s home time and the production of child quality
Authors: Fleisher Belton M. 
Published: March 2007

Abstract
This paper deals with the effect of mother’s time spent out of the labor force, and presumably in the home, on the “production” of child quality, where child quality is measured by intelligence (IQ), level of schooling attained, and market earning power. The results indicate that mother’s home time is most effective in producing (male) child quality for mothers who have attained relatively high levels of schooling. The results suggest that education programs which devote equal school resources to all (male) children do not necessarily provide equal educational opportunity and that the influence of family background on economic success is indirect, operating through home investments in children.
Family planning program activity and patient enrollment rates in the United States, 1969 and 1971
Authors: Hout Michael 
Published: March 2007

Abstract
The effects of demographic characteristics, socioeconomic conditions, health care, and family planning program activity on patient enrollment rates are estimated for 1969 and 1971. Two program activity variables (agencies and clinic locations) have significant, positive net effects in both years. The effect of agencies changed little between 1969and 1971, and it is the strongest effect in both years. The effect of clinic locations more than doubled between 1969 and 1971, partly due to increased demand. The direct effects of the demographic, socioeconomic, and health care variables are not large, but many of the demographic and socioeconomic variables have substantial indirect effects via health care and program activity.
A vital statistics-based procedure for estimating conception rates
Authors: Pullum Thomas W. , Williams Stephen J. 
Published: March 2007

Abstract
A method for estimating conception rates, using vital statistics data, is developed and applied to data on five-year age groups of California women for 1971. The approach is deterministic and allocates total exposure time to the known pregnancy outcomes of live birth, spontaneous abortion, and induced abortion. The population at risk is defined to exclude women who are known to be sterile or sexually inactive. Early fetal loss, premarital conception, and contraceptive use are taken into account. Estimates are made of the fecundability which would obtain ifno contraception were used.
The impact of breast feeding patterns on the biometric analysis of infant mortality
Authors: Knodel John , Kintner Hallie 
Published: March 2007

Abstract
A major assumption of the biometric analysis of infant mortality as developed by Bourgeois-Pichat is that the age structure of infant deaths after the first month of life is virtually constant across time and cultures. Reanalysis of results from studies which compare the mortality of infants according to the type of feeding indicated that the relationship between mortality and age within the first year of life followed different patterns for breast fed and artificially fed infants. Historical data for populations with different breast feeding customs reveal similar differences in the age pattern of infant mortality. In populations where breast feeding was uncommon or of very short duration, infant mortality rises particularly steeply during the early months of the first year of life. The age structure of infant mortality in less developed countries where breast feeding is decreasing rapidly may be similarly affected. When substantial deviations from the linear relationship are evident, particular caution is required in applying the biometric technique, since in such situations the estimated endogenous mortality is very much affected by the particular set of data points within the first year of life which are chosen for the basis of the estimates.
What difference would it make if cancer were eradicated? An examination of the taeuber paradox
Authors: Keyfitz Nathan 
Published: March 2007

Abstract
The immediate effect of discovering a way to cure cancer would be a reduction in the number of deaths in the United States by the number of people now dying from that cause. Within a short time, however, deaths from other causes would increase, and the net long-term effect would be relatively small. A parameter is derived that measures how much the expectation of life is increased by a marginal reduction in any cause of death. That parameter is additive in the several causes and has other advantages, though it does not avoid the assumption of independence.
Measuring the Effects of Race Differentials in Mortality Upon Surviving Family Members
Authors: Sutton Gordon F. 
Published: March 2007

Abstract
A model is developed to use marital history data from the U.S. Current Population Survey and mortality statistics from the federal registration system to estimate color differences in (a) the risk of widowhood among women in the working ages and (b) the cumulative duration of widowhood. Color differentials in mortality among married males are thereby translated into person-years of dependent survivorship among women, in anticipation of our later estimating average and cumulative lifetime income losses for the survivors. Initial results of this model, dealing with the demographic aspects of survivorship, are presented.
The Predictive Validity of Reproductive Intentions
Authors: Westoff Charles F. , Ryder Norman B. 
Published: March 2007

Abstract
On the basis of data collected in the 1975 National Fertility Study (NFS) in which continuously married white women interviewed in the 1970 NFS were reinterviewed five years later, the aggregate and individual validity of reported fertility intentions is evaluated. The main finding about aggregate prediction is that 1970 intentions overestimated 1971–1975 fertility to the same extent as the conventional 1970 total fertility rate. The conclusion is that intentions suffer all of the same vulnerabilities as other period measures. At the individual level, the validity of intentions is considerable in comparison with most other indicators.
Sampling variability of own-children fertility estimates
Authors: Retherford Robert D. , Bennett Neil G. 
Published: March 2007

Abstract
This paper develops methodology for estimating standard errors and confidence intervals for own-children estimates of age-specific birth rates and total fertility rates. The methodology applies to systematic samples of households, which are treated as simple random samples of women. The assumption of simple random selection, together with the treatment of sample subgroup size and reverse-survival ratios as constants instead of random variables, imply that sampling variability is slightly underestimated. The methodology is applied illustratively to fertility estimates based on the 1970 census of the Philippines.
Measuring the impact of child mortality on fertility: A methodological note
Authors: Williams Anne D. 
Published: March 2007

Abstract
Recent studies of the impact of child mortality on children ever born have used the “replacement factor” to measure mortality. When microlevel data are used, however, use of the replacement factor (or other variables which are nonlinear in the family’s experienced child mortality rate) yields biased coefficients. An alternative model suggests a sequential, rather than a static, decision-making process to relate the decision to have an additional child to the reproductive experience to date. In this case, unbiased coefficients are obtained if the functional form is correctly specified. In the absence of a priori knowledge of the functional form, it is difficult to untangle true effects from spurious ones.
Estimation of interregional migration streams from place-of-birth-by-residence data
Authors: Rogers Andrel , von Rabenau Burkhard 
Published: March 2007

Abstract
Place-of-birth-by-residence data, tabulated by age and sex for the same areal units in two successive censuses, have been used to estimate intercensal net migration flows. However, a fuller use of the same data permits the estimation of place-to-place flows. This paper describes a method for estimating intercensal migration streams from place-of-birth-by-residence data and illustrates its application with data on the white female native population of the United States.
