Population statistics and population registration in Norway. Part 3. Population censuses

In this history of Norwegian vital statistics, the author describes enumerations of population that have taken place in Norway, comments on the methods by which the results have been obtained and describes the material that has been collected.     

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.     

Development of birth registration and birth statistics in the United States

The registration of vital events in the United States has always been under the authority of State and local areas. The preparation of national birth statistics has been made possible through a co-operative working arrangement between the Federal Government and the States. This paper traces the development of registration systems in the United States from colonial days to the present period. The absence of adequate registration systems throughout the country, during the nineteenth century, led to the use of data collected in the decennial population censuses of 1850–1900 for estimating birth rates. This procedure was abandoned because of the unreliability of the results. Steps leading to the formation of the national birth-registration area in 1915, when it included ten States and the District of Columbia, and. activities resulting in its completion in 1933 are discussed.

A major portion of the paper outlines the nation-wide test of birth-registration completeness conducted in 1940 in conjunction with the decennial census of population. Important results of the test are presented, and the methodology is explained. A similar test is being carried out in 1950. Data derived will be used to focus attention on local areas requiring registration promotion. Correction factors for statistical series based on registered events will also be obtained. The final section of the paper indicates the steps States are taking to improve quality of reporting on the birth record. Changes in the content of the standard certificate of live birth since 1915 are summarized and the statistics tabulated from birth certificates detailed.     

Gender differences in the marriage and cohabitation income premium*

Using data from the 1979 National Longitudinal Survey of Youth, I identify causal effects of marriage and cohabitation on total family income. My goals are to compare men's and women's changes in financial status upon entering unions and to assess the relative contributions of adjustments in own income, income pooling, and changes in family size. Changes in own income that are due to intrahousehold specialization prove to be minor for both men and women relative to the effects of adding another adult's income to the family total. Women gain roughly 55% in needs-adjusted, total family income, regardless of whether they cohabit or marry, whereas men's needs-adjusted income levels remain unchanged when men make these same transitions.     

Maternal mortality in South Africa: lessons from a case study in the use of deaths reported by households in censuses and surveys

South Africa is unique in being a developing country which has asked questions on pregnancy-related deaths in both its 2001 census and 2007 household survey, and monitors maternal and pregnancy-related mortality through vital registration and a confidential enquiry into maternal deaths. These sources of data provide a wide range of estimates of maternal mortality for the country. This paper examines these estimates to assess to what extent the differences between them are due to data deficiencies, methodological deficiencies or definitional differences. The results show that since maternal deaths are relatively rare it is fairly difficult to establish the maternal mortality rate with a great degree of accuracy in a setting where data are less than perfect. They also show that to some extent the differences are due to differences and errors in processing of data but that pregnancy-related mortality should not be treated as synonymous with maternal mortality. However, after adjustment, pregnancy-related mortality from vital registration was comparable with the level that may be expected using several alternative approaches, while the rate reported by households in census and surveys was about double that from vital registration. Nonetheless, all the data indicate an upward trend in maternal mortality that is in keeping with the impact of the HIV/AIDS epidemic, which is likely to have contributed to the discrepancies.     

An analysis of the change of marriage pattern of Beijing women]

Changes in marriage patterns occur primarily in changes in the age at marriage. During a study of fertility among Beijing, China, women in 1981, another study was undertaken of the marriage situation of 8299 women who were born in 1914, 1920, 1930, 1940, and 1946. Data show that the rate of unmarried women was close to zero, which is one reason for the high birth rate in the past. A majority of the urban and rural women born in 1914, 1920, and 1930 married before the age of 15 years, indicating that the economic, social, and marriage customs for those decades changed very little. The 1940 cohort, however, showed no urban marriages prior to the age of 15 years and less than 1% in the villages, the reason being that these women were of marriageable age in the mid-to-late 1950s when China underwent major social and economic changes that raised the status of women and permitted them to join the work force or go to school. Very few urban women in the 1946 cohort married before 20 years of age, and the number of rural women who married before they were 18 years old declined noticeably. Findings also show that for both urban and rural women, the average age at marriage was 1-3 years later than the modal age at marriage. Beginning with the 1940 cohort the age at marriage was older by 2 1/2 years, signaling major changes. Except for the 1914 cohort, the median age at marriage for all others gradually became higher. 70% of the 1946 cohort voluntarily married after turning 23 years old, reflecting the effectiveness of the late marriage, late birth policy. Although close to 59% of rural women born in 1946 married before 23 years of age, nearly double the rate for urban women, it is nevertheless a major change from the 1930 cohort where 95% of the women married before turning 23 years old.     

Economic opportunities,marriage squeezes and the propensity to marry: An economic analysis of period marriage rates in England and Wales

An economic model of the decision to marry has been developed by Gary Becker and is now part of the ‘new home economics’. From it one can deduce that the propensity to marry is a function of the relative earning capacities of men and women, the relative scarcity of unmarried persons of the opposite sex and real income. The effects of changes in these variables on the annual first marriage rates of men aged 16–19, 20–24 and 25–29 and women aged 16–19 and 20–24 respectively are estimated over the post-war period. It is found that women's earning capacity relative to men's has a particularly strong negative effect on marriage rates, and that the decline in first marriage rates during the 1970s was primarily attributable to the growing economic opportunities for women. As demographic studies have suggested, the relative numbers of bachelors and spinsters of particular ages (‘marriage squeezes’) also have a significant impact, and there is evidence of substitution in the ages of marriage partners in response to such ‘squeezes’. The income elasticity of marriage is only found to be significant among men below age 25 and women below age 20, and it increases as we move down the age distribution. This suggests the ‘liquidity constraints’ influence the timing of marriage among young people. In sum, this economic model is able to account for over 90 per cent of the post-war variation in young persons' marriage rates.     

The relationship between childbearing and transitions from marriage and cohabitation in Britain

In this article, we describe a general framework for the analysis of correlated event histories, with an application to a study of partnership transitions and fertility among a cohort of British women. Using a multilevel, multistate competing-risks model, we examine the relationship between prior fertility outcomes (the presence and characteristics of children and current pregnancy) and the dissolution of marital and cohabiting unions and movements from cohabitation to marriage. Using a simultaneous-equations model, we model these partnership transitions jointly with fertility, allowing for correlation between the unobserved woman-level characteristics that affect each process. The analysis is based on the partnership and birth histories that were collected for the 1958 birth cohort (National Child Development Study) aged 16-42. The findings indicate that preschool children have a stabilizing effect on their parents 'partnership, whether married or cohabiting, but the effect is weaker for older children. There is also evidence that although pregnancy precipitates marriage among cohabitors, the odds of marriage decline to prepregnancy levels following a birth.     

A note on racial differences in the effecty of female economic opportunity on marriage rates

The previously observed aggregate relationship between marriage rates and female work opportunities is not found among black Americans. Alternative definitions of family formation which take illegitimacy into consideration are explored and also found to be unrelated to black females’ economic opportunities. Although some of the difference may be attributed to measurement error, the significant disparity between the two populations probably reflects substantive differences.     

Sweden's marriage revival: an analysis of the new-millennium switch from long-term decline to increasing popularity

Usually seen as a forerunner in the development of new trends in family-demographic behaviour, Sweden has recently experienced a reversal in marriage trends, from a steady decline in marriage rate between the 1960s and 1990s, to a steady increase beginning in 1998. An event-history analysis of women's first marriages in the period 1991-2007, using register data, shows that compositional changes in labour-market activity and childbearing can only partly explain the reversal, and that apparently no part of it is explained by compositional changes in age, country of birth, educational level, and type of settlement. The evidence suggests that the popularity of marriage in Sweden is increasing, in contrast to what might be expected from the way demographic trends in Sweden and other Western countries are often portrayed in the literature.     

Race and Relationship advice: Effects of marriage market differences on cultural expectations of behavior

To see if and how marriage market differences between black and white women in the US are reflected in relationship advice, relationship articles in two popular women's magazines, one targeting black women and one targeting white women, are systematically coded and analyzed. The results of this content analysis of 213 relationship articles indicate that marriage market differences are reflected in such advice. Magazine articles aimed at black women focus on men's financial problems, infidelity, and prior relationships significantly more frequently than articles targeting white women, mirroring the issues that black women face in their particular marriage market. Furthermore, the results demonstrate a greater focus on the male perspective in advice targeting black women.     

Estimates of population size and growth from the 1952-54 and 1961 censuses of the Kingdom of Nepal

Abstract The Census of Nepal conducted in 1961 conforms to the generally accepted requirements for a national census. Some doubt could be raised about the previous census as part of the country was enumerated in 1952 and part in 1954. More serious doubts still could be entertained about earlier censuses, including their very existence, though there are persistent rumours that they were carried out every ten years or so since about the middle of the previous century. We have only been able to lay our hands on some data in respect of four earlier censuses: those of 1911, 1920, 1930 and 1941. Little more is available than population totals for some of the component areas from these four censuses, and even then the boundaries and coverage of the component parts are uncertain.     

Breaking the racial barriers: Variations in interracial marriage between 1980 and 1990

Using PUMS data from the 1980 and the 1990 U.S. Census, I apply log-linear models to examine interracial marriage among whites, African Americans, Hispanics, and Asian Americans. Rarely, but increasingly between 1980 and 1990, interracial marriage of whites occurs most frequently with Asian Americans, followed by Hispanics, and then by African Americans. Interracial marriage tends to be educationally homogamous and the odds of interracial marriage increase with couples ’ educational attainment. Among interracially married couples with different educational attainments, both men and women from lower status racial groups but with high education levels tend to marry spouses from a higher status racial group with low education levels     

Age estimation from the number of teeth erupted in young children: An aid to demographic surveys

The reporting of children's ages by parents is surprisingly inaccurate in many innumerate societies, but accurate knowledge of age is important for estimating recent changes in demographic rates. The timing of the eruption of children's teeth is largely independent of environmental influences and can provide a relatively accurate and unbiased estimate of a child's age. We have collected published data from 42 studies of children's dentition and have transformed them into estimates of age for children with particular numbers of teeth. We present estimates for different populations, but the lack of significant differences between these estimates justifies the use of a standard set.
