Family size and children’s education in Vietnam

Data from the nationally representative 1994 Inter-Censal Demographic Survey are used to examine the association between family size and children s schooling in Vietnam. The data provide information on several education measures for all children over age 10, including children no longer residing in the household. Although a clear inverse bivariate association between family size and children s school attendance and educational attainment is evident, multivariate analysis controlling for urban/rural residence, region, parents’ education, household wealth, and child’s age, reveals that much of this association, especially that predicting educational attainment, is attributable to these other influences. Moreover, much of the effect that remains after statistical adjustment for the other influences is seen mainly at the largest family sizes. We consider the implications of these findings for current population policy in Vietnam and the possible features of the Vietnamese context that might account for the modest association.     

中国分代家庭户的空间分布特征研究

家庭是社会的基本组成单位,家庭户结构的变化直接影响到社会生活的各个方面,家庭户代际结构的分布则能从直观上认识家庭户结构。本文基于2000年第五次全国人口普查的分代家庭户数据及相关资料,以空间自相关分析为基础,对五普数据中的分代家庭户比例分布进行了初步分析。发现其空间分布特征呈现明显的正相关性。为了进一步研究这种空间分布,采用GIS方法得到分代家庭户比分布图,分析发现：二代户仍然是中国家庭户的主要模式;不同地区分代家庭户的分布呈现明显的差异,北方地区的二代户比例最高;三代户与四代以上户分布特征相似,主要集中在西南地区;分代家雇户的分布与绎济发展水平、宗教信仰和民族风俗密切相关．     

Parameters of Household Composition as Demographic Measures

Cross-sectional data, such as Census statistics, enable the re-enactment of household lifecourse through the construction of the household composition matrix, a tabulation of persons in households by their age and bythe age of their corresponding household-heads. Household lifecourse is represented in the household composition matrix somewhat analogously to survivorship in a life-table in demography. A measure of household lifecourse is the average household size, specific to age of household-head. Associated with the age-specific household size is the age-interval 0–4, which yields average number of children present in households, also by age of head. Trajectories of re-enacted household lifecourses for Phoenix and for the State ofArizona are depicted here to track the gamma probability density function. Through this relationship also the association between household size, children per household, and fertility emerges. To the extent that housing conditions or tenure impact average household size, or other aspects of household composition, fertility in particular is discerned as a housing- related demographic attribute of households. Household size and headship ratio, both specific to age of head, are here shown to be analytically related to the household composition matrix, their product yielding the age-specific headship coefficient. As a measure incorporating parameters of households and dwellers, thus also characterizingoccupied dwellingunits, the headshipcoefficient emerges as a demographic indicator of housing in a community.     

The index of overall headship: A simple measure of household complexity standardized for age and sex

This paper develops and tests an age-sex standardized measure of household complexity, defined broadly as the tendency of adults (other than spouses) to head their own households or to share households. The aim is a measure of household complexity which can be computed with a minimum of demographic data, namely, data on number of households and on the population by age and sex. The procedure is similar to that of Coale for fertility measurement (Coale, 1969); it is a form of indirect standardization in which the actual number of households is related to the number that would exist if maximum age-sex-specific household headship rates were to apply. Various forms of this indirectly standardized measure show a correlation of better than 0.9 with directly standardized measures for a sample of 33 nations for which requisite data are available. The new measure promises to extend considerably the geographical and temporal range of comparable empirical measures of household complexity.     

Household dynamics and fuelwood consumption in developing countries: a cross-national analysis

Previous research has suggested a link between household dynamics (i.e., average household size and number of households) and environmental impacts at the national level. Building on this work, we empirically test the relationship between household dynamics and fuelwood consumption, which has been implicated in anthropogenic threats to biodiversity. We focus our analysis on developing countries (where fuelwood is an important energy source). Our results show that nations with smaller average households consume more fuelwood per capita. This finding indicates that the household economies of scale are, indeed, associated with the consumption of fuelwood. In addition, we found that number of households is a better predictor of total fuelwood consumption than average household size suggesting a greater relative contribution to consumption levels. Thus, insofar as declining average household sizes result in increased number of households and higher per capita consumption, this trend may be a signal of serious threats to biodiversity and resource conservation. We also found further support for the ??energy ladder?? hypothesis that economic development reduces demand for traditional fuels.     

贫困地区劳动力迁移、农户收入与贫困的缓解——基于新疆农户面板数据的实证分析

本文基于新疆30个贫困县、3000个农户、2008-2010年的微观面板数据,在控制了家庭规模、劳动力数量等家庭特征变量和粮食播种面积等村庄特征变量的前提下．运用固定效应法与工具变量法分别考察了劳动力迁移规模、迁移方式与迁移区位对家庭收入的影响．并进一步分析了劳动力迁移对贫困的缓解效应。回归结果表明：劳动力迁移规模虽然对农户农业收入有负向影响．但显著提高了农户人均收入与利他性收入：自发性迁移与政府组织性迁移方式均能显著提高农户收入,且自发性迁移的作用更强;省内县外迁移对农户收入的提高最为显著,其次为县内乡外迁移．省外迁移不影响农户收入：劳动力迁移规模提高了中等收入农户的收入水平。但对贫困户的贫困无缓解效应．也不影响富裕户的收入水平。     

U.S. Family Household Momentum and Dynamics: An Extension and Application of the ProFamy Method

The classic headship-rate method for demographic projections of households is not linked to demographic rates, projects a few household types without size, and does not deal with household members other than heads. By comparison, the ProFamy method uses demographic rates as input and projects more detailed household types, sizes, and living arrangements for all members of the population. Tests of projections from 1990 to 2000 using ProFamy and based on observed U.S. demographic rates before 1991 show that discrepancies between our projections and census observations in 2000 are reasonably small, validating the new method. Using data from national surveys and vital statistics, census microfiles, and the ProFamy method, we prepare projections of U.S. households from 2000 to 2050. Medium projections as well as projections based on smaller and larger family scenarios with corresponding combinations of assumptions of marriage/union formation and dissolution, fertility, mortality, and international migration are performed to analyze future trends of U.S. households and their possible higher and lower bounds, as well as enormous racial differentials. To our knowledge, the household projections reported in this article are the first to have found empirical evidence of family household momentum and to have provided informative low and high bounds of various indices of projected future households and living arrangements distributions based on possible changes in demographic parameters.     

Poverty Among Elderly in India

Using consumption expenditure data of the National Sample Survey 2004?C2005, this paper estimates the size of elderly poor and tests the hypotheses that elderly households are not economically better-off compared to non-elderly households in India. Poverty estimates are derived under three scenarios??by applying the official cut-off point of the poverty line to household consumption expenditure (unadjusted), consumption expenditure adjusted to household size and consumption expenditure adjusted to household composition. Results show that an estimated 18?million elderly in India are living below the poverty line. On adjusting the consumption expenditure to household size and composition, there are no significant differences in the incidence of poverty among elderly and non-elderly households in India. This is in contrast to the notion that elderly households are better off than non-elderly households in India. Based on the findings, we suggest that the age dimension should be integrated into social policies for evidence based planning.     

New household projections for the united states

This paper reviews the methods used to prepare the new household projections for the United States that were recently issued by the Bureau of the Census and examines the effect on the resulting number of households of the assumptions made about future marriages and future proportions of household heads in the population.One population projection series was used, since all series are identical for the adult population. Marriage assumptions were generated by assuming various outcomes of the marriage squeeze (defined as the excess of females relative to the number of males in the main ages at marriage in the next few years). Assumptions about proportions of household heads were generated by assuming, in varying degrees, continuation of recent trends in these proportions.Projected changes in marriage and in the proportions of household heads in the population account for one-fourth to one-third of the projected increase in the number of households; the remaining increase is attributable to projected changes in the size and structure of the adult population. Varying the assumed proportions of household heads produces greater differences in the projected total number of households than does varying the marriage assumptions used here. Nevertheless, the various possible outcomes of the marriage squeeze, as represented by the assumptions used, produce significantly different projections of increases in the number of young husband-wife households.The most striking finding is that by 1985, proportions of household heads among the population not "married, spouse present" may well rise to such a level that over the long term, the smaller the number of persons who marry, the larger will be the number of households.     

Household structure and housing needs

This paper is mainly derived from the material presented in the preceding article by S. P. Brown. Indeed, while the previous analysis is of considerable intrinsic interest, the hypothetical population was constructed and its family distribution was shown for the purpose of providing a basis for estimates of housing needs. For several reasons it appeared to be essential to have such a basis. First, any housing programme has to take the future, as well as the present, distribution of households by type and size into account. Secondly, such a programme has to be designed so as not to prevent household formation—there should be dwellings for all potential households, so that involuntary doubling-up need not occur. Thirdly, most residential areas should have dwellings for an eventually stable population, that is, for one which has variety of age groups and of household types, and also fair stability of housing demand. Estimates of the distribution of potential ‘households’ could be derived from the ‘family’ distribution of the hypothetical population which reflects current demographic trends. Thus although this population is a ‘hypothetical’ one, it provides a realistic premise for considering housing needs, and because it is a ‘stationary’ one, it provides an especially suitable premise. Moreover, since the demographic characteristics of its ‘families’ and therefore of its potential households were established in far greater detail than has ever been the case in sample surveys of existing households, it was possible to classify households in the terms which appear to be most appropriate for the first draft of a housing programme, irrespective of social and economic variations in demand.

The first stage in following up Mr Brown's analysis was the conversion of ‘families’ into ‘households’. Two examples of the possible household distribution of the hypothetical population are presented. Example A, which gives a realistic, but not extreme, picture of the conversion of families into households, is used for the subsequent detailed analysis, while broader figures for distribution B are also included.

In the second stage the various types of household had to be distinguished. For estimating housing needs, two interrelated criteria of household classification are relevant—first, the stage in the life of a household, especially appropriate in considering space requirements; secondly, the age composition of households, which largely determines the type of dwelling needed.

The detailed distribution of households by size and type, based on this classification, is further translated into a distribution of dwellings by type and size. For this purpose, additional assumptions about the number of rooms and the type of dwelling needed by households of various types are introduced and applied to the hypothetical population, both to household distributions A and B. These assumptions are not based on accepted standards, nor do they suggest standards. They are merely used for the purpose of illustrating a possible method of estimating housing needs on the basis of a detailed picture of household structure. They are further designed to represent one possible compromise between economy in dwelling distribution, on the one hand, and flexibility of space for individual households, on the other.

In the final sections of the paper, the implications of the dwelling distributions here presented are discussed in relation to household mobility, and also with reference to the necessity for reconciling short-term and long-term housing needs in any housing programme.     

State and local fiscal impacts of US immigrants: Evidence from New Jersey

This paper uses a household-level estimation strategy to develop new evidence on the state and local fiscal impacts of US immigration. The methodology is applied to 1980 census microdata for New Jersey, a state that now ranks fifth in the nation in the size of its foreign-born population. All New Jersey households combined in 1980 imposed a net fiscal burden on state government of more than US$2.1 billion, and a net burden on the aggregate of all local governments totaling nearly $ 690 million. Both native- and immigrant-headed households received government benefits worth more than they paid in taxes. The typical immigrant-headed household imposed an average fiscal burden of $ 350 on local governments throughout New Jersey, versus roughly $ 225 for each native-headed household. At the state level, however, net fiscal impacts of immigrants and natives were similar: an average annual deficit of $ 841 for immigrants compared with $ 846 for native households. There are larger disparities among the foreign-born population than between native-headed and immigrant-headed households. Latin American households have the most unfavorable fiscal implications of any immigrant subgroup. Taken together, our findings illustrate the overriding importance of household income and number of school-age children as determinants of taxes paid, benefits received and, ultimately, of net fiscal impacts.     

The Effect of Women’s Empowerment in Agriculture on Household Nutrition and Food Poverty in Northern Ghana

The study examines the effect of women’s empowerment in agriculture on household nutrition—i.e. the availability of carbohydrates, protein, and fat—and household food poverty measured by monetary food shortfall. The analysis is done by applying instrumental variable estimation to a sample of 2642 households from a 2012 population-based survey conducted in northern Ghana. Overall, the results indicate that women’s empowerment positively influences nutrient availability and negatively influences monetary food shortfall. By decomposing women’s empowerment into its component domains, this study identified that the domains of Income, Production, and Leadership are areas for intervention to influence households’ nutrient availability and monetary food shortfall outcomes. The effect of the Time and Resources domains reveal that some intra-household trade-offs may exist. Thus, policies aimed at empowering women to ultimately improve household nutrition and food poverty need to be based on the understanding of these specific interactions.     

The rise of one-person households and their recent characteristics in Korea

"This paper explores the rise in the proportion of one-person households [in South Korea] which since 1960 was attributable largely to rural-to-urban migration of young people. The heavy migration of young people from rural to urban cities actually brought about the rural household division which contributed to the fall in household size, and contributed to the increase in one-person households of urban young singles, on the one hand, and the increase in one-person households of rural elderly widows, on the other. The rise in the aggregate propensity to live alone was also evident.... Although the rise in one-person households was evident and by 1990 about one out of every ten households was a one-person household, the findings on the recent characteristics of one-person households do not indicate any big change in the traditional family norms."     

Remittances in the Republic of Georgia: Correlates, Economic Impact, and Social Capital Formation

The economic impact of remittances on migrant-sending countries has been a subject of debate in the scholarly literature on migration. We consider the topic using a household-level approach. We use a new survey, “Georgia on the Move,” to examine migrant-level, household-level, and contextual variables associated with the probability that a household in the Republic of Georgia receives remittances. We then apply propensity score matching to estimate how remittances affect particular types of household expenditures, savings, labor supply, health, and other measures of well-being. Separate analysis of the subsample of households with a migrant currently abroad distinguishes the effects of remittances from the effects of migration as such. In Georgia, remittances improve household economic well-being without, for the most part, producing the negative consequences often suggested in the literature. We find evidence for an important aspect that has not been widely discussed in prior studies: remittances foster the formation of social capital by increasing the amount of money that households give as gifts to other households.     

Family household and nuptiality changes: a search for some explanations from the recent past

Using the demographic transition framework as a basis for analysis, the author examines the levels, trends, and differentials in household size and structure in the Philippines. Time-series data on average household size from the censuses show that the changes observed over time are closely associated with or have run parallel to the shifts in mortality and fertility. Data from the 1968, 1973, and 1983 National Demographic Surveys revealed small increases in 1-person households, modest increases in small-sized and moderate-sized households, and substantial decreases in large-sized households. The data also disclosed structural shifts among various types of family households. Between 1968 and 1983, family households experienced increasing nuclearization. While expectation for support in old age has somewhat diminished recently, parents' preference to join their daughters will have the effect of increasing the opportunity of females to head households. More highly educated persons exhibited a greater tendency to head the bigger-sized, extended family household, although this has diminished somewhat lately. Increases in the age at 1st marriage of both males and females affect the life span of family households, especially nuclear households. A multivariate analysis using macrolevel data as inputs demonstrated the very strong influences of the factors of desirability of marriage, availability of mate, and urbanization on the marriage pattern. Enhancing employment opportunities and creating appropriate mechanisms through which present incomes may be increased in the hinterlands under various rural development programs may help to diminish the values attached to children. The provision of more and better facilities for higher education especially in the disadvantaged provinces will enable young people, especially females, to gain access to higher learning, thus providing alternatives to early marriage and childbearing.     

Changes in household formation and composition in China since the mid-twentieth century

China has experienced great changes in household formation and composition since the mid-twentieth century, and its mean size of households has fallen from 54 persons in 1947 to 3.1 in 2005. Many of these changes, especially those taking place in the early years of the People’s Republic, have not been systematically investigated. This paper examines the impact of China’s major political, social, demographic and economic changes on household formation and composition. The study shows that changes in Chinese households have not followed a simple linear trajectory, but shown, considerable fluctuations. A drastic increase in the number of households and a sharp reduction in the mean size of households were recorded after the land reform in the early 1950s. In the next twenty years, high fertility was promoted by a generally pronatalist environment, and the mean size of households increased. Since the early 1970s, the nationwide family planning campaign has led to a rapid fertility decline and great chanes in kinship structure. The recent rise in rural-urban migration has also resulted in many unprecedented changes, and they have become major forces affecting household formation and family life in contemporary China.     

Household demographic factors as life cycle determinants of land use in the Amazon

This paper seeks to broaden the application of demographyto environmental studies by complementing existing macro-level approaches, which feature aggregate populations, with a micro-level approach that highlights household life cycles. I take up the case of small farm households in the Brazilian Amazon to present a theoretical framework that identifies demographic characteristics which dispose families to engage in different forms of land use as household age structures change. Empirical models show that net of theeffects of farmer background, neighborhood context, institutional context, and off-farm incomes, demographic variables indicative of the household life cycle exert significant effects on the prominence of land uses with distinct environmental ramifications. The findings not only reveal micro-level demographic factors which affect Amazon land cover, they yield implications forfuture changes in rainforest landscapes in northern Brazil, and suggest household life cycle models as an avenue for further demographic research on environmental change in Latin America and other contexts.     

Climate change and internal migration intentions in the forest-savannah transition zone of Ghana

Migration is at the centre of demographic research on the population–environment nexus. Increasing concerns about the impacts of environmental events on human population are fuelling interest on the relationship between migration and environmental change. Using data from the Climate Change Collective Learning and Observatory Network Ghana project, we employ binary logistic regression to examine migration intentions of households in response to major community stressors including climate-related ones. The results indicate that the type of community stressor that affects households most does not differentiate migration intentions in Ghana’s forest-savannah transition zone: Even though the majority of the respondents mentioned climate-related events as the stressor that affects them the most, such events do not appear to directly explain migration intentions. However, socio-demographic factors such as age, household size and current migration status are significant predictors of migration intentions, with younger household heads, heads of migrant households and heads of smaller households being relatively more likely to have migration intentions than other household heads. We conclude that migration drivers are multifaceted and deserve further research because even in areas with perceived environmental stress, climate-related events may not be the primary motivation for migration intentions.     

Direct Valuation of Personal Care by Households

This paper valued the quantity of child, sick, and elderly care provided by households using a new, direct measure. Such measures add to the literature that estimates the size of the contribution of non-market work by household members, particularly women, and to literature about valuation of childcare. This production remains unvalued in standard national income accounts. Traditional attempts to quantify this care multiplied care-giver hours by a wage rate, a method that suffers from several drawbacks, including omitting the contributions of anything but labor, the inability to handle joint production, and the use of an arbitrary wage rate. This study avoided these problems by valuing the amount of care with its market price based on data from a small urban area. The mean value was $3,547 annually (97 percent of it childcare) for all sample households and $9,610 for those providing care. The results afforded evidence of scale economies in parental childcare and quantified care furnished by different kinds of providers.
