Design of household sample surveys to test death registration completeness

This paper studies the design effect of counting rules, for linking deaths to housing units where they are enumerated in the survey, on the sampling variance of dual system and single system estimators of death registration completeness. It investigates estimators based on conventional rules that uniquely link each death to a single housing unit as well as estimators based on multiplicity rules which permit deaths to be linked to more than one housing unit. Sampling variance formulas are derived containing parameters that reflect the efficiency of the counting rule. Estimates of these parameters for different counting rules are compared utilizing information that was collected in a mortality survey experiment. Finally, the design of a national death registration test is considered and the sample size implications of different counting rules arc compared.

     

Cultural constructions of the concept of household in sample surveys

We analyse the use of the concept of household in sample surveys, with evidence drawn from a review of survey definitions, a series of in-depth interviews with data producers and users, and a systematic study of recent literature. We consider the place of the concept within the discipline of demography, and demonstrate how its definition and use interact with cultural values and core concepts integral to the discipline. Focusing on Tanzania as a case study, we examine the diversity of factors that influence the construction of household-level data from cross-sectional household surveys. Throughout the survey process, contrasting interpretations of the meaning of household and different motivations for using specific definitions of the term interact. This generates data and outputs with potential for undercounting, bias, and misrepresentations, with adverse effects on the quality of data used for monitoring development indicators. Some ways of improving data collection on households are proposed.

Macro-effects of changes in household preferences for children

The basic ideas underlying the analysis in this paper are that family size can be viewed as an economic life cycle decision and that there are decision trade-offs among fertility, consumption, and leisure. A micromodel of life cycle choice is developed and embedded in an economic-demographic macromodel. The macromodel is then used in a series of computer experiments to assess the effects on the population and the economy of changes in household preferences for children. The experiments include factual and counterfactual simulations of Canadian historical demographic experience and simulations of alternative future scenarios. The analysis and conclusions have general relevance for countries that have been through a fertility boom-and-bust sequence.We are grateful for the support received from Health and Welfare Canada's Review of Demography and Its Implications for Social and Economic Policy and from the Social Sciences and Humanities Research Council of Canada. We are grateful also to Christine H. Feaver, who carried out the computer-related aspects of the work on which this paper is based.     

Historical changes in the household division of labor

A number of studies published in the 1970s asserted that the amount of time women spend doing housework shows no historical decline. This article draws on evidence from time-budget surveys—three from the United States (1965, 1975, and 1985) and three from the United Kingdom (1961, 1974, and 1984)—to investigate the evolution of housework time for men and women over the last three decades. Clearly much other than housework has changed over this period. More women have paid jobs, more men are unemployed, and families have gotten smaller on average. Even having controlled for such sociodemographic changes, we conclude that in the two countries, women in the 1980s do substantially less housework than those in equivalent circumstances in the 1960s, and that men do a little more than they did (although still much less than women). These changes correspond closely to developments in four other countries (Canada, Holland, Denmark, and Norway) for which historical time-budget evidence is available.     

The role of non-timber forest products in household coping strategies in South Africa: the influence of household wealth and gender

The prevalence and ranking of non-timber forest products (NTFPs) as safety-nets has been well discussed, but rarely quantified. We report on group discussions and household interviews in two South African villages to assess the frequency and nature of shocks and stresses over a 2-year period and the coping strategies employed, stratified by household wealth and gender of the de jure household head. Overall, kinship was the most widely adopted coping strategy, and NTFPs were the fifth most prevalent (employed by 70% of households). There were relatively few differences in the nature of shocks or responses between male- and female-headed households. Wealth influenced the experience of shocks or stresses as well as responses. Poorer households have fewer options with the increased use or sale of NTFPs being the second most commonly adopted strategy. Increased use and sale of NTFPs is a common manifestation of the safety-net function. To reconcile long-term economic development and biodiversity conservation, it is important to understand people??s use of natural resources and the factors that affect this use, including their responses to shocks and stresses.     

Differences in mortality by marital status in Finland from 1976 to 2000: analyses of changes in marital-status distributions, socio-demographic and household composition, and cause of death

Being currently not married is more common today than 25 years ago. Over this period relative differences in mortality by marital status have increased in several countries, mainly as a result of a sharp decline in mortality among the married. Using Finnish census data linked with death certificates, we show that these increases are not explained by the non-married population becoming more marginalized in socio-economic status or household composition. However, the increases in marital-status differences in mortality from accidental, violent, and alcohol-related causes of death in the 30-64 age group indicate that changes in the health-related behaviour of the non-married population may play a role. The public-health burden associated with not being married has also grown. At the end of the 1990s about 15 per cent of all deaths above the age of 30 would not have occurred if the non-married population had had the same age-specific mortality rates as the married population.     

Correlations,causes and heuristics in surveys of life satisfaction

Satisfaction with life domains is more highly correlated with interpersonal than with intrapersonal comparisons (Emmons and Diener, 1985). The hypothesis of the present studies is that the high correlations reflect inferences of social comparison from global satisfaction. Paradoxically, such inferences are most likely in private domains (love life, friends), where social information is scarce and relatively unimportant as a determinant of satisfaction. Study I replicates the Emmons-Diener findings, but also finds that subjects judge recent changes more important than social standing as a determinant of life satisfaction, especially in private domains. Study II examines an order effect in judgments of satisfaction. As hypothesized the correlation between social comparison and global satisfaction is higher (in private domains only) when global satisfaction is judged first than when the order of judgment is reversed.     

Sources of error in reported childlessness in a continuous British household survey

A recent investigation of the British General Household Survey (GHS) found substantial over-reporting of childlessness in recent years, particularly at older ages. We examine the phenomenon in further detail and find that the principal cause was change in survey procedures. To some extent the bias can be corrected for by using information on own children in the household. Revised fertility histories give period estimates of total fertility that are in close agreement with national vital registration statistics, unlike those based on original fertility histories of recent years. Misreporting in fertility histories dates primarily from administrative changes in the GHS in the years 1998-2000, and particularly from 2003, when the option of laptop self-completion (CASI) was introduced for reporting demographic histories.     

Influences of household structure and composition on breast-feeding

Researchers applied longitudinal data on 2884 women who were at least 6 months pregnant between May 1983-April 1984 and living in the Cebu metropolitan area, the Philippines to examine assumptions which may explain the association between lower breast feeding levels and dwindling social support for mothers who breast feed in urban areas. Extended family households were much more common in urban areas than rural areas (46.3% vs. 27.5%). This finding did not support the 3rd assumption of falling extended family patterns with urbanization. Further as the levels of complexity and extension of the household rose so did infant care support regardless of location. For example, the number of hours of help with infant care for mothers in nuclear families in urban areas was 1.23 which climbed from 2.53 for horizontal extended families to 2.9 for vertical extended families and to 3.09 for horizontal and vertical extended families. This result supported the 2nd assumption of much more social support in extended families than nuclear families. Yet social support did not translate into promotion of breast feeding--the 1st assumption. Mothers in horizontally extended families had a lower likelihood of breast feeding than those in nuclear families. Further only adult female relatives of the same generation as the mother has a negative influence on breast feeding in urban mothers, but not rural mothers. In fact, female children of at least 7 years old, female servants, and yayas all negatively affect breast feeding in urban mothers, but not rural mothers. In rural households, young female relatives (at least 7 years old) significantly increased the probability of breast feeding whereas young male relatives decreased the probability.     

Household division of labor and cross-country differences in household formation rates

This paper considers the extent to which the gender division of labor affects the likelihood of household formation. Using repeated cross sectional data covering highly-developed nations, we consider the differential effects of aggregate social norms regarding the division of household labor. Controlling for other factors that affect the marriage market, our findings indicate that more egalitarian norms are associated with an increase in the probability of forming a household. When additionally controlling for individual attitudes, we find that, ceteris paribus, more egalitarian women are less likely to form a household, while more egalitarian men are more likely to do so. This pattern of results is consistent with economic models of the marriage market where partners contract over the future household division of labor. Moreover, given the salience of household formation as a proximate determinant of fertility, our results potentially shed light onto the process of below replacement fertility and the economic challenges associated with it.

Size and structure of the household in England over three centuries

Abstract Data giving sizes and structures of households have been rare for any country before the institution of the official census, and have to be gleaned from surviving documents containing listings of inhabitants. This article, the first of two, describes the collection of listings of inhabitants of English communities which is being assembled by the Cambridge Group for the History of Population and Social Structure and the methods by which the hundred most informative of them have been submitted to analysis. When ranged alongside the information on mean household size derived from the official British census since its inception in 1801, the results of this analysis suggest the following. 1. Mean household size in England and Wales as a whole was relatively constant at 4·75 or a little below for the whole period from the sixteenth century until 19II, and has only fallen since that date. The reduction of about one-third starting in 1921 may therefore be the first of considerable magnitude ever to occur: it seems to have been particularly rapid between 1911 and 1931. 2. Mean household size in England and Wales has been surprisingly resistant to demographic fluctuation on the one hand and to the structural influences of industrialization on the other, until the last fifty or sixty years. 3. The traditional household in England has never been extended on any definition, at least since the sixteenth century. Mean household size varied with social status, and a majority lived in households of six or more members. But this distribution was due to the very large numbers of servants living in and not to the presence of resident kin, who seem to have been rare. 4. The relationship between fertility, mortality and mean household size is different from what has been supposed. This article ends by registering the paradox that proportion of children in a pre-industrial English community apparently seems to be negatively, not positively, related to its mean household size, and this theme will be taken up in the second article. These four points are illustrated by a series of tables drawn from the analysis of the one hundred communities.     

The impacts of climate variability on household welfare in rural Mexico

In light of the expected increase in weather variability from climate change, we examine the impact of weather shocks, defined as rainfall or growing degree days more than a standard deviation from their respective long-run means, on household consumption per capita. The analyses suggest that both rainfall and temperature shocks affect both food and non-food consumption. Furthermore, the results show that a household’s ability to protect its consumption from weather shocks depends on the climate region and when in the agricultural year the shock occurs. Especially, households in arid climates are not fully protected from weather shocks occurring during the beginning of the wet season (April, May, June). The results highlight the necessity to account for the underlying climatic variation as well as to carefully define the shocks.     

Differentiation of voivodeships in terms of the number of children in the household

The author attempts to answer the question, "Are the numbers of households [in Poland] with specific numbers of supported children (structures) in the total number of households similar or dissimilar in all voivodeships, and where [are these] identical (similar) or dramatically different?" Results indicate that "the most differentiated voivodeships, in terms of the number of children below 24 years of age supported by households, were voivodeships of north-eastern and south-eastern Poland. In the case of male heads of households the number of voivodeships making up areas of the highest differentiation regarding the number of children below 24 years is definitely bigger than for the female heads of households."     

Rationale and procedures for nesting semi-structured interviews in surveys or censuses

Demographers who use survey data and census data from health and demographic surveillance areas can gain substantially from expanding their repertoire of methods to make use of qualitative methods. Similarly, those who conduct and analyse data primarily from semi-structured interviews or focus groups can benefit from information provided by survey research. This paper presents a systematic mixed-methods model-data-linked nested studies-for sampling respondents for semi-structured interviews from survey or census lists. The paper outlines how to conduct these types of study, and their technical and analytical advantages. It highlights the benefits of building on a strong foundation, the ability to compare samples, and the expansion of the range of evidence for, or against, the validity of the substantive findings. Case studies from two data-linked nested projects-in Malawi and South Africa-are used to describe in detail the nested-study approach.     

A longitudinal analysis of household and nonhousehold living arrangements in later life

Most explanatory models of living arrangements in later life link the decision process surrounding choice of living arrangement to personal resources such as income and health. Applications of these models, however, are based for the most part on cross-sectional rather than longitudinal data. In this paper we examine living arrangements in later life among the nonmarried population aged 55 and over, using data from the Survey of Income and Program Participation. We observe individuals as they change living arrangements, die, or become institutionalized. Our results suggest that economic resources dominate the decision-making process in transitions across different household arrangements, whereas health is most important in explaining institutionalization.
