The Location of Displaced New Orleans Residents in the Year After Hurricane Katrina

Using individual data from the restricted version of the American Community Survey, we examined the displacement locations of pre–Hurricane Katrina adult residents of New Orleans in the year after the hurricane. More than one-half (53 %) of adults had returned to—or remained in—the New Orleans metropolitan area, with just under one-third of the total returning to the dwelling in which they resided prior to Hurricane Katrina. Among the remainder, Texas was the leading location of displaced residents, with almost 40 % of those living away from the metropolitan area (18 % of the total), followed by other locations in Louisiana (12 %), the South region of the United States other than Louisiana and Texas (12 %), and elsewhere in the United States (5 %). Black adults were considerably more likely than nonblack adults to be living elsewhere in Louisiana, in Texas, and elsewhere in the South. The observed race disparity was not accounted for by any of the demographic or socioeconomic covariates in the multinomial logistic regression models. Consistent with hypothesized effects, we found that following Hurricane Katrina, young adults (aged 25–39) were more likely to move further away from New Orleans and that adults born outside Louisiana were substantially more likely to have relocated away from the state.     

Population recovery in New Orleans after Hurricane Katrina: exploring the potential role of stage migration in migration systems

In this research brief, we explore how places affected by natural disasters recover their populations through indirect, or “stage,” migration. Specifically, we consider the idea that post-disaster impediments (e.g., housing and property damage) in disaster-affected areas spawn migration flows toward and, over time, to disaster-affected areas through intermediary destinations. Taking as our case Orleans Parish over a 5-year period after Hurricane Katrina, we show that stage migration accounted for up to about one-fourth of population recovery. We close by discussing the implications, limitations, and potential extensions of our work.     

我国人口流动中的健康选择机制研究

利用2008年中国流动与健康调查数据,对农村留守人口、农村外出返乡人口、乡城流动人口以及城镇居民等不同流动特征群体之间的健康差异进行比较,并系统检验了我国人口流动过程中的两种健康选择机制——"健康移民"(healthy migrant)效应和"三文鱼偏误"(salmon bias)效应。模型分析结果表明,我国人口流动存在着较为明显的"健康移民"和"三文鱼偏误"选择效应。在控制被访者的年龄、性别、主要社会经济特征以及相关健康行为后,流动人口自评一般健康、慢性病状况、经常性身体不适和肺活量等健康指标显著优于农村留守人口,乡城流动人口患有慢性病和出现经常性身体不适的可能性也显著低于农村返乡人口。在控制相关变量后,乡城流动人口与城镇居民的健康状况(除慢性病和心率过高症状外)不存在显著差别。     

Disaster disparities and differential recovery in New Orleans

The historical disparities in the socio-demographic structure of New Orleans shaped the social vulnerability of local residents and their responses to Hurricane Katrina and its aftermath. These disparities, derived from race, class, gender, and age differences, have resulted in the uneven impact of the catastrophe on various communities in New Orleans, and importantly, their ability to recover. This article examines how the pre-existing social vulnerabilities within New Orleans interacted with the level of flood exposure to produce inequities in the socio-spatial patterns of recovery. Utilizing a combination of statistical and spatial approaches, we found a distinct geographic pattern to the recovery suggesting that the social burdens and impacts from Hurricane Katrina are uneven—the less flooded and less vulnerable areas are recovering faster than tracts with more vulnerable populations and higher levels of flooding. However, there is a more nuanced story, which suggests that it is neighborhoods in the mid-range of social vulnerability where recovery is lagging. While private resources and government programs help groups in the high and low categories of social vulnerability, the middle group shows the slowest rates of recovery. Further, it appears that the congressionally funded State of Louisiana Road Home Program (designed to provide compensation to Louisiana’s homeowners who suffered impacts by Hurricanes Katrina and Rita for the damage to their home) is not having a significant effect in stimulating recovery within the city.     

Trends in the relationship between socioeconomic status and infant mortality in metropolitan Ohio, 1960–1990

This paper presents the results of an ecological analysis of the relationship between infant mortality and economic status in metropolitan Ohio at four points in time centering on the censuses of 1960, 1970, 1980 and 1990. The basic unit of analysis is the census tract of mother's usual residence, with economic status being determined by the percentage of low income families living in each tract. For each period, the census tracts were aggregated into broad income groups and three-year average infant mortality rates were computed for each area, by age, sex, race and exogenous-endogenous causes of death. The most important conclusion to be drawn from the data is that in spite of some very remarkable declines in infant mortality for all socioeconomic groups since 1960, there continues to be a very clear and pronounced inverse association between income status and infant mortality. Indeed, there is some evidence to suggest that it is stronger in 1990 than it was three decades earlier. The general inverse association is observed for both sexes, for whites and nonwhites, and for all major causes of death. At the same time, the data reveal notable variations in the pattern of the relationship over time, as well as several differences between whites and nonwhites in the nature and magnitude of the relationship. Some macro-economic hypotheses are offered to explain these temporal and racial differences in the pattern of the relationship between economic status and infant mortality.This article is an expanded version of a paper presented at the annual meetings of the Southern Demographic Association in New Orleans, 21–23 October 1993.     

Quality of Life and Perceptions of Crime in Saskatoon, Canada

This article investigates the relationship between crime and quality of life in Saskatoon, Canada. The city has one of the highest crime rates in the country and has been referred to as the ‘Crime Capital of Canada’, a label that comes as a surprise to many residents and causes considerable concern among others. The aim of this research is to penetrate beyond sensational news headlines and bald crime statistics. The paper evaluates how perceptions of crime and safety affect the quality of life of residents living in neighbourhoods of different socio-economic status and geographic location. Both quantitative and qualitative time series data is analyzed in a sample of neighbourhoods over the period 2001–2004–2007. The findings of the data analysis are interpreted with respect to issues relating to the fear of crime, avoidance behaviour, risk minimization, social cohesion and community building.     

Post-disaster fertility: Hurricane Katrina and the changing racial composition of New Orleans

Large-scale climate events can have enduring effects on population size and composition. Natural disasters affect population fertility through multiple mechanisms, including displacement, demand for children, and reproductive care access. Fertility effects, in turn, influence the size and composition of new birth cohorts, extending the reach of climate events across generations. We study these processes in New Orleans during the decade spanning Hurricane Katrina. We combine census data, ACS data, and vital statistics data to describe fertility in New Orleans and seven comparison cities. Following Katrina, displacement contributed to a 30% decline in birth cohort size. Black fertility fell, and remained 4% below expected values through 2010. By contrast, white fertility increased by 5%. The largest share of births now occurs to white women. These fertility differences—beyond migration-driven population change—generate additional pressure on the renewal of New Orleans as a city in which the black population is substantially smaller in the disaster’s wake.     

Social costs of displacement in Louisiana after Hurricanes Katrina and Rita

Hundreds of thousands of Louisiana citizens were displaced from their homes as a result of Hurricanes Katrina and Rita. Of those displaced within Louisiana some relocated to other parishes, some to other residences within the same parish, and others were able to return to their pre-storm residence. This article draws upon data gathered by the 2006 Louisiana Health and Population Survey to examine the social costs of displacement across 18 Louisiana parishes approximately 1 year after the hurricanes. Specifically, we examine how displacement affected housing, economic, and health outcomes for individuals and families. Further, we compare the implications of two types of displacement (1) internal displacement—within-parish relocation versus (2) external displacement—relocation across parish lines. We found that the displaced had lower odds of owning their homes, living in detached housing, and retaining access to primary health care facilities. The displaced were also more likely to be unemployed and exhibit symptoms consistent with severe mental illness. The externally displaced suffered income declines. These trends are critically important for understanding both the short- and long-term ramifications of displacement after disaster. Our findings have implications for theories, policy makers, and planners considering the larger social costs of disaster and large-scale displacement.     

Ecological correlates of psychiatric illness in the City of Calgary

Hospital admissions for psychiatric disorders in the City of Calgary were reviewed during a six-month period. Rates of hospitalization for the city's 77 census tract areas were calculated and correlated with data collected in the 1976 Canada Census. The study identified areas in the city with high rates of pathology requiring hospitalization. The correlational analysis reveals a significant association between differential admission rates and demographic and ecological attributes such as age, marital status, population stability, housing tenure, crowding, social disintegration and isolation and unemployment. Of these correlates, the proportion of persons aged 65 years and over and the number of families in each of the census tract areas were shown to be the most important factors influencing rates of psychiatric hospitalization.     

Socioeconomic Inequalities in Infant Mortality in Egypt: Analyzing Trends Between 1995 and 2014

This paper analyses the trend of the socioeconomic inequalities in infant mortality rates in Egypt over the period 1995–2014, using repeated cross-sectional data from the National Demographic and Health Survey. A multivariate logistic regression and concentration indices are used to examine the demographic and socioeconomic correlates of infant mortality, and how the degree of socioeconomic disparities in child mortality rates has evolved over time. We find a significant drop in infant mortality rates from 63 deaths per 1000 live births in 1995 to 22 deaths per 1000 live births in 2014. However, analyzing trends over the study period reveals no corresponding progress in narrowing the socioeconomic disparities in childhood mortality. Infant mortality rates remain higher in rural areas and among low-income families than the national average. Results show an inverse association between infant mortality rates and living standard measures, with the poor bearing the largest burden of early child mortality. Though the estimated concentration indices show a decline in the degree of socioeconomic inequality in child mortality rates over time, infant mortality rate among the poor remains twice the rate of the richest wealth quintile. Nonetheless, this decline in the degree of socioeconomic inequality in child mortality is not supported by the results of the multivariate logistic regression model. Results of the logistic model show higher odds of infant mortality among rural households, children who are twins, households with risky birth intervals. We find no statistically significant association between infant mortality and child’s sex, access to safe water, mothers’ work, and mothers’ nutritional status. Infant mortality is negatively associated with household wealth and regular health care during pregnancy. Concerted effort and targeting intervention measures are still needed to reduce the degree of socioeconomic and regional inequalities in child health, including infant mortality, in Egypt.     

Housing and wealth inequality: Racial-ethnic differences in home equity in the United States

In our study, we took a first step toward broadening our understanding of the sources of both housing and wealth inequality by studying differences in housing equity among blacks, Hispanics, Asians, and non-Hispanic whites in the United States. Using data from the American Housing Survey, we found substantial and significant gaps in housing equity for blacks and Hispanics (but not for Asians) compared with whites, even after we controlled for a wide range of locational, life-cycle, socioeconomic, family, immigrant, and mortgage characteristics. Furthermore, the payoffs to many factors are notably weaker for minority than for white households. This finding is especially consistent across groups for the effects of age, socioeconomic status, and housing-market value. Blacks and Hispanics also uniformly receive less benefit from mortgage and housing characteristics than do whites. These findings lend credence to the burgeoning stratification perspective on wealth and housing inequality that acknowledges the importance of broader social and institutional processes of racial-ethnic stratification that advantage some groups, whites in this case, over others.     

城市外来人口居住条件对其健康影响之考察——以上海为例

本文利用上海2008年的抽样调查数据,考察了一个特别重要但是长期被忽视的群体——城市外来人口居住条件和健康的问题。通过与本地居民的对比,发现外来人口的身心健康好于本地居民,但在居住条件、尤其是住房条件各方面均表现出对本地居民的明显劣势。回归分析结果说明,控制人口和社会经济变量,居住条件的确是影响城市外来人口健康的重要社会因素之一,但对于不同的健康指标,不同居住条件变量作用的大小和方向有所不同。此外,对居住条件与户籍身份的交互作用分析显示,居住条件对城市外来人口健康的影响总体上弱于对本地居民健康的影响,不同的居住条件变量对城市外来人口与本地居民健康的影响关系有所不同。这一结论将有助于政府部门制定更加适合外来人口的改善居住条件与健康状况的相关政策。     

Going home after Hurricane Katrina: Determinants of return migration and changes in affected areas

This article examines the decision of Hurricane Katrina evacuees to return to their pre-Katrina areas and documents how the composition of the Katrina-affected region changed over time. Using data from the Current Population Survey, we show that an evacuee’s age, family income, and the severity of damage in an evacuee’s county of origin are important determinants of whether an evacuee returned during the first year after the storm. Blacks were less likely to return than whites, but this difference is primarily related to the geographical pattern of storm damage rather than to race per se. The difference between the composition of evacuees who returned and the composition of evacuees who did not return is the primary force behind changes in the composition of the affected areas in the first two years after the storm. Katrina is associated with substantial shifts in the racial composition of the affected areas (namely, a decrease in the percentage of residents who are black) and an increasing presence of Hispanics. Katrina is also associated with an increase in the percentage of older residents, a decrease in the percentage of residents with low income/education, and an increase in the percentage of residents with high income/education.     

The making of a ghetto: Spatially concentrated poverty in New York City in the 1980s

In recent years a debate has arisen over which of two mechanisms — class selective household mobility or spatially focused increases in poverty — has been the driving force in concentrating poverty in certain inner-city neighborhoods. This paper utilizes a multivariate analysis to identify the processes underlying areal income-class transition in New York City during 1978–1987, and the areal characteristics that predict a consistent path of change. By anchoring the analysis at the level of the individual housing unit, this study disentangles the competing mechanisms of poverty concentration and demonstrates that both selective mobility and shifts in income class contribute to areal income-class transition, but that the latter mechanism accounts for a greater amount of change. Further, after controlling for the proportion of minority residents and public housing units in the area, the results show that location in poor areas is associated with poor in-movement, nonpoor out-movement, and downward shifts in the income class among long-term residents. These mutually reinforcing processes lead to continued decline in extreme- and high-poverty areas, while processes in the opposite direction sustain the economic vitality of low-poverty areas.An earlier version of this paper was presented at the 1992 meetings of the Population Association of America in Denver, Colorado.     

Job Displacement and First Birth Over the Business Cycle

In this article, we investigate the impact of job displacement on women’s first-birth rates as well as the variation in this effect over the business cycle. We use mass layoffs to estimate the causal effects of involuntary job loss on fertility in the short and medium term, up to five years after displacement. Our analysis is based on rich administrative data from Germany, with an observation period spanning more than 20 years. We apply inverse probability weighting (IPW) to flexibly control for the observed differences between women who were and were not displaced. To account for the differences in the composition of the women who were displaced in a downturn and the women who were displaced in an upswing, we use a double weighting estimator. Results show that the extent to which job displacement has adverse effects on fertility depends on the business cycle. The first-birth rates were much lower for women who were displaced in an economic downturn than for those who lost a job in an economic upturn. This result cannot be explained by changes in the observed characteristics of the displaced women over the business cycle.     

Population Trends as a Counterweight to Central City Decline, 1950–2000

The share of metropolitan residents living in central cities declined dramatically from 1950 to 2000. We argue that cities would have lost even further ground if not for demographic trends such as renewed immigration, delayed childbearing, and a decline in the share of households headed by veterans. We provide causal estimates of the effect of children on residential location using the birth of twins. The effect of veteran status is identified from a discontinuity in the probability of military service during and after the mass mobilization for World War II. Our results suggest that these changes in demographic composition were strong enough to bolster city population but not to fully counteract socioeconomic factors favoring suburban growth.     

The relationship between apartment living and fertility for blacks,Mexican Americans,and other Americans in Racine,Wisconsin

Recently published data from a sample of Bogotá, Colombia public housing residents show that apartment dwellers, but not house dwellers, reduced their fertility in a tight housing market. We propose that the utilitycost theory of fertility accounts for this finding, and, using this theory, we predict that (a) apartment residents will not decrease their fertility in an open housing market and (b) higher fertility will be associated with larger dwellings. Longitudinal data from a sample of Midwest urban blacks, Mexican Americans, and other Americans support both predictions. The substantive implications are discussed.     

中国超大城市常住外来和常住户籍人口居住－就业的空间错位--基于北京、上海和广州的实证

以北京、上海、广州作为中国超大城市的代表,探讨中国超大城市常住外来和常住户籍人口居住－就业空间错位的差异及其影响因素。总体而言,常住外来人口的居住－就业空间错位要高于常住户籍人口,且不同户籍属性人口的错位形态存在差异。分行业来看,公共管理和社会组织等公共服务业常住外来人口居住－就业空间错位程度相对较高,而制造业、居民服务和其他服务业常住户籍人口居住－就业空间错位程度相对较高。由计量分析发现,住房价格水平、就业集聚规模、高端产业比重和地区地方财政支出对不同户籍属性人口就业－居住空间分布差异均产生相似的影响;而租赁户数比重和低端产业比重对不同户籍属性人口的就业－居住空间分布则产生差异性的影响。     

Human Empowerment and Trust in Strangers: The Multilevel Evidence

This study aimed to develop a social cohesion index for understanding the social relation between residents in high-rise group housing complexes through a self-reported questionnaire. As a background of the study, literature on social cohesion and related literature on residents’ social relation in high-rise housing were reviewed. Later, we selected different high-rise group housings of Kolkata, a city in the eastern region of India. We conducted few focus group surveys involving the residents of those high-rises and also conducted expert opinion surveys to identify a context-specific list of statements for evaluating residential social cohesion. Finally, based on the responses of interviews from 652 residents of the identified high-rise housings from the same city, followed by confirmatory factor analyses, three factors of residential social cohesion were identified with adequate reliability and validity. This index holds huge potential to explore residential social relation in high-rise housing and carry out empirical studies, across various disciplines, in other cities in the country and outside the country of similar socio-economic and cultural context.     

(Un)natural disaster: vulnerability,long-distance displacement,and the extended geography of neighborhood distress and attainment after Katrina

After Hurricane Katrina, socioeconomically vulnerable populations were slow to return to their poor and segregated pre-disaster neighborhoods. Yet, very little is known about the quality of their post-disaster neighborhoods. While vulnerable groups rarely escape neighborhood poverty, some Katrina evacuees showed signs of neighborhood improvement. The current study investigates this puzzle and the significance of long-distance moves for neighborhood change among participants in the Resilience in the Survivors of Katrina Project. Seven hundred low-income, mostly minority mothers in community college in New Orleans before Katrina were tracked across the country a year and a half later. The findings show that respondents’ immediate and extended neighborhoods and metropolitan areas after Katrina were less disadvantaged, less organizationally isolated, and more racially and ethnically diverse compared to their pre-hurricane environments, and to the environments of those staying or returning home. Counterfactual analyses showed that more than within-neighborhood changes over time, between-neighborhood mobility and long-distance migration decreased respondents’ exposures to distress in their neighborhood, extended geographic area, and metropolitan area.
