A note on occupation statistics in British censuses

The census occupation statistics are the most complete source of information on the employment of the population during the past century. The Official Guide to the Census Reports¹ traces the development of the occupation inquiries and gives details of the major classification changes (pp. 27-43). These changes are considered in relation to each census year, but little attempt has been made to examine their effect on the comparability of the data. In addition, certain points which are of interest to research workers in this field have been omitted from the Guide.     

A note on nineteenth-century Irish emigration statistics

Summary On the basis of a re-examination of the different statistical series of post-Famine Irish emigration, this paper finds (1) that the total outflow was larger than the figures for total emigration allow, and (2) that permanent movement to Great Britain was substantially more important, both relatively and absolutely, than is commonly realized.     

African urban life: Components of satisfaction in Sierra Leone

This comparative study finds relatively high satisfaction with the quality of life in three Sierra Leonean towns, but there are notable differences between men and women and between the towns in which domains support this satisfaction. The standard of living achieved, and the job and income which make it possible, are the most important factors in satisfaction with the quality of urban life, but the limits on women's mobility are indicated by the greater emphasis they place on housing and neighborhood. Dissatisfaction among the relatively advantaged, with their own position and with the country's progress in development, reflects the political disaffection of some members of this group.     

Population statistics and population registration in Norway. Part 1. The vital statistics of Norway: An historical review

From olden times in Norway, as also in Sweden and Denmark, the church official in each parish has kept the official registers of marriages, births and deaths, and has produced the records which form the basis of Norwegian vital statistics.

The demographic viewpoint in the vital and health statistics monographs of The American Public Health Association

The plan calls for monographs on 16 specific topics and a review volume. The specific topics include a monograph on fertility, another on marriage and divorce, and one on social and economic factors in mortality, all of which are of obvious demographic interest. The core of the development of the monographs dealing with the disease topics, and accidents, homicide, and suicide, is a tabulation program involving specific and age-adjusted death rates based upon the deaths in the United States for the three year period 1959-61 and the 1960 census of population. The program called for a set of standard tabulations common to each monograph and also a set of special tabulations tailored to meet the particular needs for each topic as specified by its authors. This wealth of demographic detail regarding mortality in the United States during 1959-61 fills only one aspect of its health picture. To fill out the health picture, use is being made of the great volume of morbidity data out of the National Health Interview and Examination Surveys and a wide variety of other specialized surveys. In all of these, the findings are invariably described in terms of the demographic characteristics of age and sex, and frequently in terms of such social-economic variables as education, income, work status, and occupational class.A large part of the content of the monograph on social and economic factors in mortality will come out of available results of the 1960 census-death certificate matching study at the University of Chicago. One important feature of this monograph, not contained in the Chicago study, is a regression and correlation analysis of total mortality in 202 Standard Metropolitan Statistical Areas in relation to a large number of social, economic, and climatic factors. Among the features in the monograph on fertility are chapters on the medical and biological characteristics of births, fecundity and family planning, and an analysis of cohort fertility trends. The monograph on marriage and divorce will make use of the detailed tabulations from the 1960 census on marital status in relation to education, race, parentage, earnings and other classifications of individuals and of husband and wife in married couples. It will also contain a matching study of divorce records in certain states for a short period before the census of 1960 with the returns in the census. The project is supported by a grant from the United States Public Health Service (CH 00075; formerly RG 08262). Publication will be by the Harvard University Press.     

A note on mortality in Jamaica

This article analyses briefly various aspects of mortality in Jamaica. After an appraisal of available vital statistics, the mortality trend, as revealed in several measures, is traced and brief comparison with other West Indian colonies made. A discussion of the marked differential between legitimate and illegitimate infant mortality leads to the conclusion that the higher rate of the latter is associated with lower socio-economic status of the parents. Mortality from a few causes of death is also analysed and the possibility of improvement stressed. The probable consequences of declining mortality are illustrated by examining the probable growth of the population to 1951 in three broad age groups.     

Some features of a peasant population in the Middle East

In the region popularly known as the Middle East data about the populations are very scanty, and it is suggested that the Cyprus census of 1946, including as it does fairly full information about a peasant people with distinct Christian (Greek) and Moslem (Turkish) communities, may provide a useful source of comparison for larger countries in the neighbourhood. The paper discusses the rapid growth of population in the last seventy years, and the features of nuptiality, fertility and mortality which have given rise to this growth. It deals also with the changes in the sex-ratio of each community and with the trend of movement from rural areas into towns.     

Differential fertility in peasant communities: A study of Six Iranian Villages

Summary This paper attempts to study the relation between socio-economic status and fertility in a sample of six villages in Iran. An index of socio-economic status was constructed. The data reveal positive association between socio-economic status and fertility behaviour of rural couples. When duration of marriage, age of woman at marriage and contraceptive use were introduced into the socio-economic status-fertility relationships, they failed to alter the original findings. Because socio-economic status is related to a number of variables which directly or indirectly influence fertility, additional variables such as miscarriage, stillbirth and lactation must be incorporated into rural surveys on fertility differentials.     

A note on differential fertility in Sri Lanka

In this paper an attempt has been made to study differential fertility by urban-rural and regional classifications, using data obtained from complete tabulations of the 1963 Census of Population, the four rounds of the Socio-Economic Survey conducted from November 1969 to October 1970, and the Registrar General's Department. The analysis of current fertility indicates that the traditional pattern of lower urban fertility relative to rural held true in both 1963 and 1970 and also shows a narrowing of the differentials. The country was divided into four zones on an agro-climatic basis for regional analysis. A consistent ranking of the zones in relation to current fertility emerges in both 1963 and 1970. Changing patterns of age-specific fertility and age-specific marital fertility are discussed. Data on average size of family by urban-rural and regional classifications are also analyzed. An attempt has also been made to identify some of the possible causes for the differentials observed.     

A note on nursing practices in an American isolate with a high birth rate

Abstract An unusually short interval between successive births in a non-contracepting and breast-feeding population has been reported by Dr. Mindel C. Sheps (Pop. Studies, 19, 1). Nursing practices that might affect the interval between birth and pregnancy are reported here from systematic observations made in the field. Probable factors are: (1) a maternal diet high in calories and in protein; (2) although infants are nursed for many months, each nursing period is short in a busy and highly patterned community schedule; and (3) supplementary feeding is introduced at an early age.     

A note on suicide in Russia, 1965–1993

Recently, theCentre for Demography and Human Ecology in Moscow in collaboration with theInstitut National d’études Démographiques in Paris undertook a reconstruction of registered deaths in individual republics of the former Soviet Union. The first set of such data, tabulated by sex, age and cause of death, covers the deaths registered in Russia between 1965 and 1993. The present article extracts from the data set information on registered suicide mortality and reviews its trends and age and sex patterns. The link between alcoholism and suicide is strongly suggested.     

A note on the use ofregression methods in population estimates

Evidence which has emerged in the past few years indicates that the relative accuracy of population estimates derived from the ratio-correlation method and the difference-correlation method varies from state to state. In assessing the possible reasons why neither technique is uniformly more accurate, attention is focused on the temporal instability of the statistical relationships between symptomatic indicators and population change. The author concludes that further improvement in population estimates based on regression techniques is likely to be limited until demographers derive means of measuring and adjusting for these temporal changes.     

A comparison of different survey techniques for obtaining vital data in A developing country

This article presents estimates of the sources and the extent of observation errors in different questionnaires and methods used to collect birth and death data in the 1961-63 multi-purpose sample survey of Morocco.The questionnaires used in the analysis of the three survey rounds were a list of household members (Rounds1 and 2) and a roll-call (Round3); retrospective death (Rounds1, 2, and 3) and birth (Round 3) queries; a date-of-birth tabulation (Round 2); and a household check-sheet to explain differences between Rounds 1 and 2. All available questionnaires for a given household were brought together and collated to provide several sources of information on births and deaths and a basis for assessing errors.From this analysis, the survey attempted to define the nature and to estimate the frequency of the errors which would have occurred if more restricted types of survey design had been used. Results, based on the period between Rounds 1 and 2, led to three major conclusions.First, if vital data had been collected with a single-round retrospective procedure, gross error (over enumeration plus underenumeration) would have been 17 percent for births and 36 percent for deaths. There is a net error of overenumeration of 3 percent for births (1.4 per1,000population) and 9 percent for deaths (2.3 per1,000population).Second, if two rounds were available to permit a combination of household composition follow-up and a retrospective mortality questionnaire, overenumeration would be almost entirely eliminated and underenumeration would be noticeably reduced. Third, most of the remaining errors of underestimation may be attributed to (1) an estimated number of infants born and deceased between two rounds and missed by all questionnaires, (2) matching failures caused by the absence of adults at Round 1, and (3) matching errors.     

A note on the analysis of parity progression ratios

Contingency table modeling procedures are proposed to examine the effects of independent variables on parity progression ratios. The methodology is outlined and an incremental-factorial linear model is developed.     

A note on the population of seventeenth century London

A least-squares analysis of the various estimates of the population of London during the seventeenth century discloses the probable degree of error in the work of William Petty and other early demographers. A new “average” population is calculated and the regression equation given which best satisfies the contemporary estimates.     

A further note on the estimation of a fitness function from two samples taken from a popolation

Summary A modification is proposed for the moments method for estimating a fitness function that was discussed in an earlier paper (Manly, 1976b). This modification ensures that fitness estimates are always positive. The theory has been worked out for a fitness function of any number of variables and a computer program has been written to carry out the iterative calculations needed for estimation.     

A note on the rate of intergenerational convergence of earnings

We show that “convergence” to mean earnings in intergenerational earnings mobility models will be a function not only of the single-generation correlation of earnings, but also of the properties of the unobserved stochastic distribution of shocks to earnings.

A note on the under-registration of births in Britain in the nineteenth century

In this note an attempt has been made to estimate the incompleteness of birth registration in Great Britain in the first decades of civil registration. For Scotland, registration appears to have been reasonably complete after 1861. For England and Wales, however, there seems to have been a considerable initial deficiency, with a consistent improvement over time and no sudden change following the 1874 amending Act. The estimates given in this note suggest that, to allow for under-registration in England and Wales, registered births should be multiplied by a factor of about 1.094 for the period 1841-5, the factor falling steadily to 1.o by 1880. It should be emphasized that the methods of estimation used in this note are indirect and the results very approximate. In the view of the writer, the estimates tend in general to be somewhat too low, especially for the earlier part of the period covered.
