Abstract:The main purpose of this paper stems from the need for a systematic study of the multiple components that determine the factors that attract residents of urban centers to rural areas in Greece. Based on Multicriteria Analysis (Explanatory Factor Analysis and Hierarchical Analysis) of the last censuses data (2001–2011), the main types (spatial patterns) of Greek municipalities that have potential prospects for settlement are assessed. At the same time, age profiles of people who tend to enter specific types of municipalities are explored, highlighting both the attractiveness factors of the rural areas and what the internal migrant is looking for at the settlement destination. Distinct spatial patterns of counterurbanization can be identified in Greece based on age, physical amenities, employment structures, offer of services, degree of isolation, and the cost of living in the recipient location. Finally, the results identify that spatial, demographic, social and economic inequalities are decisive in the interpretation of internal migration flows.
摘要:本文的主要目的源于需要对决定希腊城市中心居民向农村地区吸引的因素的多个组成部分进行系统研究。基于上一次人口普查数据(2001-2011)的多标准分析(解释因素分析和层次分析),评估了具有潜在定居前景的希腊城市的主要类型(空间模式)。同时,研究了倾向于进入特定类型城市的人口的年龄特征,突出了农村地区的吸引力因素以及内部移民在定居目的地的寻找。在希腊,可以根据年龄、物质便利设施、就业结构、提供的服务、隔离程度和接收地的生活成本确定不同的反城市化空间模式。最后,研究结果表明,空间、人口、社会和经济不平等在解释国内移徙流动方面具有决定性作用。

Abstract:Birth interval is the period between two live births of a woman. In Indonesia, the National Family Planning Agency recommends a birth interval of between 36–60 months to reduce the risk of maternal and child mortality. The objective of this research is to analyze birth intervals and their relationship with infant mortality using survival analysis of data from the 2017 Indonesia Demographic and Health Survey. Infant mortality was calculated using person-years, and Kaplan-Meier curves were used to describe the relationship between infant mortality and preceding birth interval. The Cox proportional hazard model was used for multivariate analysis, revealing a negative relationship between birth interval and infant mortality. For each one-year increase in birth length, there is a reduction in infant mortality of 11.9 percent. This study also shows that the economic status of mother significantly affects infant mortality, with babies born to poor mothers 1.84 times more likely to die.
摘要:生育间隔是指女性两次活产之间的时间间隔。在印度尼西亚,国家计划生育机构建议生育间隔在36-60个月之间,以减少孕产妇和儿童死亡的风险。本研究的目的是利用2017年印度尼西亚人口与健康调查数据的生存分析来分析出生间隔及其与婴儿死亡率的关系。婴儿死亡率以人-年计算,Kaplan-Meier曲线用于描述婴儿死亡率与产前间隔之间的关系。采用Cox比例风险模型进行多变量分析,发现出生间隔与婴儿死亡率呈负相关。出生长度每增加一年,婴儿死亡率就会降低11.9%。这项研究还表明,母亲的经济地位显著影响婴儿死亡率,贫困母亲所生婴儿的死亡率是贫困母亲的1.84倍。

Analyzing the Trend of Life Expectancy Evolution in Algeria from 1962 to 2018: The S-logistic Segmentation with Jumps 阿尔及利亚1962 - 2018年预期寿命演变趋势分析:S-logistic跃变分割

Abstract:This paper analyzes the evolution of life expectancy in Algeria since Independence in 1962, using an epidemiological transition framework. The general transition trend was fitted with an S-logistic function, while a break-point analysis – including jumps – was performed to detect methodological changes and extreme event effects. Results show evidence of the epidemiological transition of the Algerian population. Apparent jumps in the time series of life expectancy evolution appear to be due to updates of the correction factors for death under registration, misestimation of the population structure during the intercensal periods, and impacts of the civil war during the 1990s.
摘要:本文利用流行病学过渡框架分析了阿尔及利亚自1962年独立以来预期寿命的演变。总体过渡趋势用S-logistic函数拟合,同时进行断点分析(包括跳跃)以检测方法学变化和极端事件效应。结果显示阿尔及利亚人口的流行病学转变的证据。预期寿命演变时间序列的明显跳跃似乎是由于更新了登记死亡的校正因子、两次人口普查期间对人口结构的错误估计以及1990年代内战的影响。

Abstract:This article investigates interracial marriage as part of a social reproduction process, looking at to what extent parental endogamy influences the endogamy of a child and how parental race affects the race of a child’s spouse. Data from the Brazilian Social Survey (PESB) for the year 2002 and logit models are used. The characteristics of parental union may influence the choice of a child’s partner through different mechanisms: i) socialization, ii) structural aspects of the individual’s marriage market, and iii) direct parental influence regarding partner choice. The results show that, on average, children of racially endogamous couples are about 78.8% more likely to be in an endogamous union themselves than in a racially exogamous marriage. Parental education is also significant. This means that higher parental education leads to an increased probability of an endogamous union. The results by type of parental union show that parental race matters only for exogamous couples, and an individual’s own race is more relevant among children of endogamous parents. The results for the analysis of parental race and the race of a child’s spouse show that having nonwhite parents decreases the probability of a child marrying a white spouse. For this specific case, parental education is not statistically significant. These results reinforce the race hierarchy in the process of racial assortative mating, when considering an individual’s own race and the race of their parents. The aspect of the intergenerational transmission of racial endogamy, as it relates to partner choice, is also clarified.
摘要:本文将跨种族婚姻作为社会再生产过程的一部分进行研究,考察父母的内婚制在多大程度上影响子女的内婚制,以及父母的种族如何影响子女配偶的种族。数据来自2002年巴西社会调查(PESB)和logit模型。父母结合的特点可能通过不同的机制影响孩子对伴侣的选择:1)社会化;2)个人婚姻市场的结构方面;3)父母对伴侣选择的直接影响。结果显示,平均而言,种族内婚夫妇的孩子自己成为内婚伴侣的可能性比种族外婚夫妇的孩子高78.8%。父母的教育也很重要。这意味着父母的教育程度越高,内婚结合的可能性越大。父母结合类型的结果表明,父母种族只对外婚夫妇有影响,而一个人自己的种族与内婚父母的孩子更相关。对父母种族和孩子配偶种族的分析结果表明,拥有非白人父母会降低孩子与白人配偶结婚的可能性。在这个特殊的案例中,父母的教育在统计上并不显著。当考虑到一个人自己的种族和他们父母的种族时,这些结果加强了种族分类交配过程中的种族等级。还澄清了种族内婚制代际传播的方面,因为它与伴侣选择有关。

Does the Field of Study Affect Entry into Motherhood? Evidence from Italy 学习领域会影响成为母亲吗?来自意大利的证据

Abstract:Differences in the transition to first motherhood in Italy have usually been explained using women’s educational attainment, income, or employment instability. Our aim is to analyse whether, and how, entries into motherhood also vary by field of study. Drawing on the Indagine Longitudinale delle Famiglie Italiane (ILFI) up to 2005, we ran discrete-time hazard rate models. The results show that in Italy highly educated women trained in science and technology are not the least prone to enter into motherhood. Rather, three distinct groups of women emerge: a) those with a general upper secondary diploma and with a degree in medicine, who are the least likely to become first-time mothers; b) those with a degree in teaching and psychology, who are the most likely to become mothers; c) those trained in all other fields, who show no difference in timing to first birth. Thus, the woman’s level and type of education seem to matter much less than what has been found in other countries. In a context with still relatively traditional gender roles and family formation processes, and with relatively weak returns to education, education appears to matter most in the transition to first union.
摘要:在意大利,人们通常用女性的受教育程度、收入或就业不稳定性来解释向第一母亲过渡的差异。我们的目的是分析是否,以及如何,进入母性也因研究领域而异。利用意大利纵向家庭想象(ILFI)至2005年的数据,我们运行了离散时间风险率模型。结果表明,在意大利,受过高等教育的受过科学和技术训练的妇女并非最不容易成为母亲。相反,出现了三种不同的妇女群体:a)拥有普通高中文凭和医学学位的妇女,她们成为第一次母亲的可能性最小;B)拥有教学和心理学学位的人最有可能成为母亲;C)那些在所有其他领域受过训练的人,他们在第一次生育的时间上没有区别。因此,与其他国家相比,女性的教育水平和类型似乎不那么重要。在性别角色和家庭形成过程仍然相对传统,教育回报相对较弱的背景下,教育似乎在向第一次婚姻过渡的过程中最重要。

Abstract:Artificial neural network (ANN) models are rarely used to forecast population in spite of their growing prominence in other fields. We compare the forecasts generated by ANN long short-term memory models (LSTM) with population projections from the traditional cohort-component method (CCM) for counties in Alabama, USA. The evaluation includes projections for all 67 counties, which are diverse in population and socioeconomic characteristics. When comparing projected values with total population counts from the 2010 decennial census, the CCM used by the Center for Business and Economic Research at the University of Alabama in 2001 produced comparable or better results than a basic multi-county ANN LSTM model. Results from ANN models improve when we use single-county models or proxy for a forecaster’s experience and personal judgment with potential economic forecasts. The results indicate the significance of forecaster’s experience/judgment for CCM and the difficulty, but not impossibility, of substituting these insights with available data.
摘要:人工神经网络(ANN)模型虽然在其他领域越来越突出,但很少用于人口预测。我们将人工神经网络长短期记忆模型(LSTM)与传统队列成分法(CCM)的人口预测结果进行了比较。评估包括对所有67个县的预测,这些县的人口和社会经济特征各不相同。当将预测值与2010年十年一次人口普查的总人口进行比较时,2001年阿拉巴马大学商业和经济研究中心使用的CCM比基本的多县ANN LSTM模型产生了相当或更好的结果。当我们使用单一国家模型或代理预测者的经验和个人判断与潜在的经济预测时,人工神经网络模型的结果会得到改善。结果表明预报员的经验/判断对CCM的重要性,以及用现有数据替代这些见解的难度,但并非不可能。

Abstract:This study addresses how perception of risk of child mortality, land ownership and household type influence fertility preferences. The study focuses on four distinct villages: two vulnerable to cyclones and floods and two not usually subject to the impacts of extreme weather events (EWEs). The study uses a mixed-methods approach in collecting relevant information from 759 randomly selected ever-married women at reproductive age who had at least one child and were living with their husband during the field survey. The descriptive findings demonstrate that fertility preferences vary regarding perceived risk of child death, land ownership and household type, and that the influences of these factors vary for areas vulnerable to EWEs and not vulnerable to EWEs. Binary logistic regression analysis reveals that perceived risk of child death from EWEs and land ownership are the significant covariates in areas vulnerable to EWEs. In contrast, experience with child death, land ownership and household type are the most influential covariates explaining variation in fertility preferences in the areas not vulnerable to EWEs. The findings of the study can inform policy recommendations in terms of effective disaster management programs and family planning initiatives during climate-related events.
摘要:本研究探讨了儿童死亡风险感知、土地所有权和家庭类型对生育偏好的影响。这项研究的重点是四个不同的村庄:两个容易受到飓风和洪水的影响,两个通常不受极端天气事件(ewe)的影响。该研究采用混合方法收集了759名随机选择的育龄已婚妇女的相关信息,这些妇女至少有一个孩子,在实地调查期间与丈夫住在一起。描述性研究结果表明,生育偏好因感知到的儿童死亡风险、土地所有权和家庭类型而异,这些因素的影响在易受生态环境影响的地区和不易受生态环境影响的地区有所不同。二元logistic回归分析显示,在环境污染严重的地区,儿童死亡的感知风险和土地所有权是显著的协变量。相反,儿童死亡经验、土地所有权和家庭类型是最具影响力的协变量,可以解释在不容易受到环境影响的地区生育率偏好的变化。研究结果可以为气候相关事件期间有效的灾害管理方案和计划生育举措提供政策建议。

Parental Mortality and Outcomes among Minor and Adult Children 未成年和成年子女的父母死亡率和结果
IF 0.7 Q4 DEMOGRAPHY Pub Date : 2019-08-27 DOI: 10.1353/prv.2019.0006

Abstract:In this paper, I take advantage of newly available data in the Survey of Income and Program Participation (SIPP) to document outcomes among individuals with deceased parents. I focus first on minors and find that about 2 million children in the United States have a biological mother or father who is deceased. This is the first direct estimate of the size of the orphan population in the United States. Relative to children with both parents living, these maternal and paternal orphans have less favorable educational and health outcomes but similar levels of economic well-being. I find the Social Security program provides extensive (but not universal) support to the child survivor population, with participation in the program potentially affected by the earnings of deceased parents prior to death and by awareness of benefit eligibility by adult members in the child’s household. Similar to outcomes for child survivors, I find adult respondents who have deceased parents at the time of the SIPP have less favorable educational and health outcomes. In contrast to child survivors, adults with deceased parents – across a wide range of age groups – are more likely to have low levels of economic well-being. I also find, by examining a past legislative change in Social Security student benefits that would have affected several cohorts in the SIPP, that financial resources available to young adult survivors have effects on educational attainment and effects on income much later in life.
摘要:在本文中,我利用收入和计划参与调查(SIPP)的新数据来记录父母去世的个人的结果。我首先关注未成年人,发现美国大约有200万儿童的生母或生父已经去世。这是对美国孤儿人口规模的首次直接估计。与父母都健在的儿童相比,这些双亲孤儿的教育和健康状况较差,但经济福利水平相似。我发现社会保障计划为幸存的儿童提供了广泛(但不是普遍)的支持,参与该计划可能会受到已故父母在去世前的收入以及儿童家庭中成年成员对福利资格的认识的影响。与儿童幸存者的结果类似,我发现在SIPP期间父母去世的成年受访者的教育和健康结果不太有利。与幸存的儿童相比,父母去世的成年人——在各个年龄段——更有可能处于较低的经济福利水平。我还发现,通过研究过去社会保障学生福利的立法变化,年轻的成年幸存者可以获得的经济资源对他们的教育程度和以后的收入都有影响。

I also find, by examining a past legislative change in Social Security student benefits that would have affected several cohorts in the SIPP, that financial resources available to young adult survivors have effects on educational attainment and effects on income much later in life.","PeriodicalId":43131,"journal":{"name":"Population Review","volume":"53 1","pages":"-"},"PeriodicalIF":0.7,"publicationDate":"2019-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85188201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract:Infant mortality is an important population health statistic that is often used to make health policy decisions. For a small population, an infant mortality rate is subject to high levels of uncertainty and may not indicate the “underlying” mortality regime affecting the population. This situation leads some agencies to either not report infant mortality for these populations or report infant mortality aggregated over space, time or both. A method is presented for estimating “underlying” infant mortality rates that reflect the intrinsic mortality regimes of small populations. The method is described and illustrated in a case study by estimating IMRs for the 15 counties in California where zero infant deaths are reported at the county level for the period 2009–2011. We know that among these 15 counties there are 50 infant deaths reported at the state level but not for the counties in which they occurred. The method’s validity is tested using a synthetic population in the form of a simulated data set generated from a model life table infant mortality rate, representing Level 23 of the West Family Model Life Table for both sexes. The test indicates that the method is capable of producing estimates that represent underlying rates. In this regard, the method described here may assist in the generation of information about the health status of small populations.
摘要:婴儿死亡率是一项重要的人口卫生统计数据,经常用于卫生政策的制定。对于少数人口来说,婴儿死亡率具有高度的不确定性,可能无法表明影响人口的"基本"死亡率制度。这种情况导致一些机构要么不报告这些人口的婴儿死亡率,要么报告按空间、时间或两者合计的婴儿死亡率。提出了一种估算反映小群体内在死亡率制度的“潜在”婴儿死亡率的方法。在一项案例研究中,对2009-2011年期间县一级无婴儿死亡报告的15个县的综合死亡率进行了估计,对该方法进行了描述和说明。我们知道,在这15个县中,州一级报告了50例婴儿死亡,但没有报告发生婴儿死亡的县。该方法的有效性是用一个模拟数据集形式的合成人口来测试的,该数据集是由一个模型生命表生成的,代表了West家庭模型生命表的第23级,包括男女。测试表明该方法能够产生表示潜在比率的估计。在这方面,这里描述的方法可能有助于产生关于少数人口健康状况的信息。

Abstract:Following distinctive trends toward urbanization and suburbanization, spatially heterogeneous demographic dynamics are increasingly reflective of different development trajectories at both urban and metropolitan scales. A comprehensive investigation of population trends along homogeneous cycles of urban expansion–with identification of the most relevant factors of growth and change–is still lacking for several European cities. On this point, the present study investigates spatio-temporal patterns of urban expansion in 174 metropolitan regions of Europe, comparing population trends in inner cities and suburbs during a relatively long-time interval (1950-2000). A mixed (parametric/ non-parametric) statistical approach was developed with the aim to profile the specific socioeconomic context underlying population growth (or decline). A comparative analysis of population trends in inner cities and suburbs allows identification of similarities and differences in urbanization patterns and processes across Europe and contributes to define metropolitan clusters associated with a specific background context. The empirical results of this analysis give a more complete representation of contextual factors of population growth and decline in European cities, outlining the increased demographic polarization in inner cores and suburbs during the earlier phases of urbanization. Evidence for higher heterogeneity and fragmentation of long-term population trends during the late phases of urbanization brings further insights in the debate over the future development of contemporary cities.
摘要:随着城市化和郊区化的发展趋势,空间异质性的人口动态越来越多地反映出城市和大都市尺度上的不同发展轨迹。对城市扩张同质周期的人口趋势的全面调查,以及对增长和变化的最相关因素的识别,在几个欧洲城市仍然缺乏。在这一点上,本研究调查了欧洲174个大都市区城市扩张的时空格局,比较了1950-2000年较长时间间隔内城市内城和郊区的人口趋势。开发了一种混合(参数/非参数)统计方法,目的是描述人口增长(或下降)背后的特定社会经济背景。对内城和郊区人口趋势的比较分析可以确定整个欧洲城市化模式和进程的异同,并有助于确定与特定背景有关的大都市集群。该分析的实证结果更完整地反映了欧洲城市人口增长和下降的背景因素,概述了城市化早期阶段内核和郊区人口两极分化的加剧。在城市化的后期阶段,长期人口趋势的异质性和碎片化程度较高,这一证据为有关当代城市未来发展的辩论提供了进一步的见解。
