EPICENTRES OF MISSING DAUGHTERS

The spatial spread of the female child deficit in India has been explored in terms of hot spots (with high deficits) and cold spots (with more female-favourable child sex ratios). It has been argued, using the Census of India data from individual censuses, that there is a contagion effect for both hot spots and cold spots. This paper takes this discussion forward by asking whether such an effect can be seen across censuses. To do so, it develops the concept of an epicentre to see whether a hot or cold spot in one census spreads shock waves across a wider region in later censuses. The longitudinal analysis of child sex ratios over three censuses—1991, 2001 and 2011—shows that the hot spots are epicentres for the spread of female child deficits, while the cold spots display a reverse effect.     

Postcodes and the 1991 census of population: issues,problems and prospects

"The decade between the 1981 and 1991 UK Censuses of Population has seen an enormous increase in the use of the postcode system for locational referencing. To date, no direct means have existed for linking postcoded data to census geography at the most detailed level, but the production of a new ED/postcode directory promises to offer a range of new opportunities for postcode applications following the release of the 1991 Census data. This paper reviews the characteristics of the postcode system, describes the new directory, and examines the methods which will be available for linking the Census and postcodes post-1991."     

Quantifying Indonesia's Ethnic Diversity

Ethnicity used to be a political taboo in Indonesia, a country with more than 600 ethnic groups, but this has changed since the advent of the Reform era (1998). The government of Indonesia (through Statistics-Indonesia) included a question on ethnicity in its 2000 population census, and continued in the 2010 census. This paper produces the first estimates of ethnic diversity at the national, provincial, and district levels using tabulations provided by Statistics-Indonesia based on the full enumeration data set of the 2010 Indonesia Population Census. It analyzes three measurements of ethnic diversity: the percentage of the largest ethnic group, Ethnic Fractionalization Index (EFI), and Ethnic Polarization Index (EPOI). This paper provides a quantitative start for further studies to link ethnic diversity with many social, economic, and political variables, including studies on the dynamics of ethnic diversity. We conclude that Indonesia is relatively ethnically fractionalized, though not as polarized. Among provinces and districts, we have seen a continuum ranging from ethnically homogeneous to heterogeneous, from the least fractionalized to the most fractionalized, and from the least polarized to the most polarized province or district. Variation in ethnic diversity is also seen across islands although provinces and districts in the Island of Java are more likely to be homogeneous, less fractionalized and less polarized than provinces and districts outside Java Island.

On hunger and child mortality in India

Despite accelerated growth there is pervasive hunger, child undernutrition and mortality in India. Our analysis focuses on their determinants. Raising living standards alone will not reduce hunger and undernutrition. Reduction of rural/urban disparities, income inequality, consumer price stabilization, and mothers’ literacy all have roles of varying importance in different nutrition indicators. Somewhat surprisingly, public distribution system (PDS) do not have a significant effect on any of them. Generally, child undernutrition and mortality rise with poverty. Our analysis confirms that media exposure triggers public action, and helps avert child undernutrition and mortality. Drastic reduction of economic inequality is in fact key to averting child mortality, conditional upon a drastic reordering of social and economic arrangements.     

The Scale of Dissimilarity: Concepts, Measurement and an Application to Socio-Economic Variation Across England and Wales

The paper considers the scale – the measure, extent, and dimension – of uneven distributions in space for a wide range of census variables. While the traditional 'index of dissimilarity' is affected by random as well as social factors, a solution presented here allows the index to be calculated even for very small populations. Small areas across England and Wales tend to be fairly similar demographically but quite diverse on ethnic and socio-economic measures. Differences between areas become more noticeable as we move from districts, to wards, to enumeration districts, but the rate of differentiation depends heavily on the variables considered.     

Trends in the residential mobility of seniors in Canada, 1961–2006

This article examines residential mobility for seniors 65 years of age and older in Canada using census data from 1961–2006. We addressed three questions. First, have seniors been increasingly likely to change their residential location within Canada or alternatively become increasingly likely to age‐in‐place? Second, has the in‐migration of seniors to Canada from other countries become more pronounced over the years? Third, does the residential mobility of seniors vary by age and sex? We used census data to calculate the percentages of seniors who changed their residence in the five‐year periods prior to each of the 1961–2006 censuses and the percentages of seniors who moved in the previous year for the 1991–2006 censuses. We calculated the percentages of seniors making local moves, longer distance moves within the same province, moves from one province to another, and moves to Canada from another country. We found that rates of residential mobility for seniors tended to increase in the 1961–1981 period but have been lower and relatively consistent from 1986–2006. We found no evidence to suggest a pattern of sustained increase in residential mobility of seniors. We conclude that Canadian seniors tend to age‐in‐place and that when seniors do change residence, the likelihood of residential mobility decreases with the distance of the move and decreases with age. Nevertheless, the likelihood of changing residence may increase for seniors 75+ years of age who need assistance and are at risk of institutionalization. We found that senior women were more likely to change residence locally than senior men. Finally, we found that from 1961 to 2006 between 0.8 percent and 1.4 percent of seniors had migrated to Canada in the five years prior to each census from other countries and that this pattern has fluctuated over the past half century with no clear trend.     

MEASURES OF INCOME INEQUALITY AND SOCIAL POLARIZATION IN CANADIAN METROPOLITAN AREAS

Rising inequality and polarization of employment earnings have been clearly documented in Canada and most other developed economies in the 1990s. Following a critical discussion of the use of the Cini coefficient as a measure of inequality in geography, the level of inequality and social polarization of household incomes at the census tract level is assessed for Canada's 22 largest Census Metropolitan Areas. The distribution of household income among metropolitan census tracts is generally becoming more unequal. In addition, the proportion of households in middle-income census tracts is declining in most metropolitan centres, lending further support to arguments that Canada's middle class is in decline .
L'augmentation des intégalité et la polarisation des revenus d'emploi a été clairement documentee au Canada et dans la plupart des autres pays industrialises durant les annees 90. Á la suite d'une discussion critique sur l'utilisation du coefficient Gini comme mesure d'inégalite en geographie, on evalue le niveau d'inegalitéet la polarisation sociale des revenus menagers au niveau du secteur de recensement pour les 22 plus grandes regions metropolitaines de recensement au Canada. La distribution du revenu des menages parmi les secteurs de recensement metropolitains devient en général plus idgale. De plus, le fait que la proportion des menages parmi les secteurs de recensement d revenus moyens est d la baisse dans la plupart des regions métropolitaines soutient l'idee que la classe moyenne est en diminution.     

Adult Male Mortality in India

This paper presents levels and trends of adult male mortality in India and its major states during the post-independence period applying the widowhood method on census data. It also estimates adult male mortality for all the districts from major states of India. We adjusted widowhood estimates for possible bias due to remarriages and examined the sensitivity of adjusted estimates to different scenarios of remarriage rates. Comparison of widowhood estimates with direct estimates from official sources supports the credibility of widowhood estimates. Information obtained from widows aged 40–44 and 45–49 provided the most convincing patterns of adult mortality. Trends in adult mortality suggest that maximum gain in ₄₅q₁₅ for India and its states occurred during 1949–1960. Adult male mortality varied substantially across the states of India. Although adult life expectancy has been rising in India, the rate of mortality reduction has been decreasing over the last few decades.     

Dimensions and dynamics of residential segregation by income in urban Canada, 1991–1996

This paper examines the trends in residential segregation by income (post-transfer, pretax income) in the thirty-nine largest Canadian urban areas between 1991 and 1996. The study is motivated by the relative lack of attention paid to residential segregation by income in the Canadian context and by conceptual arguments linking compromised life chances and increased social tensions for the populations of highly segregated cities. We investigated several dimensions of segregation using five different measures (we focus on three of these here given the correlation structure of the measures) to examine changes in segregation between 1991 and 1996, a period characterised by economic recession, cutbacks in social programs and a widening of inequality in market incomes at the national scale. Overall, income segregation increased in most urban areas across all dimensions of segregation during the time period, with particularly high degrees of segregation observed in prairie cities (Winnipeg, Saskatoon and Regina). Of the three largest metropolitan areas (Vancouver, Toronto and Montréal), Montréal was the most consistently segregated. We also find that increases in spatial separation and spatial concentration by income occurred despite the fact that at the national scale, the tax and transfer system appeared to be adequately redressing a rise in inequality in labour and market incomes (as demonstrated by the lack of change in post-transfer national income inequality measures during a period when inequality in market and labour incomes rose sharply). This implies that the lived experience of changes in income distribution are unlikely fully captured by aspatial, national-scale measures and that intra-urban measures with a spatial dimension are an important indicators of inequality in Canadian society.     

Residential property disparities in city districts in Prague,Czech Republic

City districts are often classified as ‘rich’ or ‘poor,’ a phenomenon that occurs within cities all over the world. While income inequality, wealth inequality, and other kinds of social inequality are frequently tracked, there is a surprising lack of research concentrating on how social inequality manifests as differences between parts of cities, especially outside of the U.S. That is mostly due to insufficient available data. In this paper, we propose a methodology for measuring the relative inequality between city districts by using the average prices of residential properties in various parts of the city, and assessing their relative difference. This approach has several advantages, as property listings are often readily available even in cities where income data is not. This methodology has potential for measuring developments in inequality in a much wider range of cities. As a proof of concept, we apply this methodology to property prices in Prague during the period 2003–2012 to identify a trend of either growing or decreasing inequality among individual parts of the city. We have found that during this period the disparity has grown only 5.97%, which means the overall growth of disparity between the city districts was negligible.     

INEQUALITY IN CITIES*

ABSTRACT Much of the inequality literature has focused on national inequality, but local inequality is also important. Crime rates are higher in more unequal cities; people in unequal cities are more likely to say that they are unhappy. There is a negative association between local inequality and the growth of city‐level income and population, once we control for the initial distribution of skills. High levels of mobility across cities mean that city‐level inequality should not be studied with the same analytical tools used to understand national inequality, and policy approaches need to reflect the urban context. Urban inequality reflects the choices of more and less skilled people to live together in particular areas. City‐level skill inequality can explain about one‐third of the variation in city‐level income inequality, while skill inequality is itself explained by historical schooling patterns and immigration. Local income also reflects the substantial differences in the returns to skill across, which are related to local industrial patterns.

Ghettos in Canada's cities? Racial segregation,ethnic enclaves and poverty concentration in Canadian urban areas

Recent literature suggests a growing relationship between the clustering of certain visible minority groups in urban neighbourhoods and the spatial concentration of poverty in Canadian cities, raising the spectre of ghettoization. This paper examines whether urban ghettos along the U.S. model are forming in Canadian cities, using census data for 1991 and 2001 and borrowing a neighbourhood classification system specifically designed for comparing neighbourhoods in other countries to the U.S. situation. Ecological analysis is then performed in order to compare the importance of minority concentration, neighbourhood classification and housing stock attributes in improving our understanding of the spatial patterning of low-income populations in Canadian cities in 2001. The findings suggest that ghettoization along U.S. lines is not a factor in Canadian cities and that a high degree of racial concentration is not necessarily associated with greater neighbourhood poverty. On the other hand, the concentration of apartment housing, of visible minorities in general, and of a high level of racial diversity in particular, do help in accounting for the neighbourhood patterning of low income. We suggest that these findings result as much from growing income inequality within as between each visible minority group. This increases the odds of poor visible minorities of each group ending up in the lowest-cost, least-desirable neighbourhoods from which they cannot afford to escape (including social housing in the inner suburbs). By contrast, wealthier members of minority groups are more mobile and able to self-select into higher-status 'ethnic communities'. This research thus reinforces pleas for a more nuanced interpretation of segregation, ghettoization and neighbourhood dynamics.     

The Geography of Economic Development and Racial Discrimination in Brazil

This study investigates the relationship between unequal resource and population distribution and racial wage inequality in Brazil. Using sample data from the 1980 Brazilian census, monthly wages were estimated for white and Afro-Brazilian men working in nine metropolitan areas. Estimates showed that racial disparities in wages existed across all regional labour markets. Regression-based decomposition analysis found that a substantial portion of the racial wage gap was due to discrimination (unequal pay), while estimates of the magnitude of labour market discrimination indicated considerable variation by geographical area. Discrimination was higher in the predominantly white and highly developed areas of the South than in the former slave and underdeveloped regions of the Northeast.     

Female Demographic Disadvantage in India 1981–1991: Sex Selective Abortions and Female Infanticide

Using evidence from a number of sources (including the 1981 and 1991 censuses of India, prior research, and NGO reports), this article examines whether bias against girl children persists during periods of development and fertility decline, whether prenatal sex selection has spread in India as elsewhere in Asia, and whether female vs. male child mortality risks have changed. The authors present estimated period sex ratios at birth (SRBs) calculated by reverse survival methods along with reported sex ratios among infants aged 0 and 1, as well as sex ratios of child mortality probabilities (q5), from the two censuses. The findings show an increase in ‘masculine’ SRBs and persistent (or even worsening) female mortality disadvantage, despite overall mortality decline, due to selective neglect and the spread of female infanticide practices in some areas. Research and reports indicate the increasing use of prenatal sex selection in some regions. In India, preference for sons appears to be undiminished by socio-economic development, which interacts with cultural sources of male bias. The increased masculinity of period SRBs in some areas, together with persistent excess female child mortality and female infanticide, creates a ‘double jeopardy’ for girl children. Legislation curbing prenatal sex determination and policy measures addressing societal female devaluation have had little impact, suggesting that female demographic disadvantage is unlikely to improve in the near future.     

Sex inequality in the Māori population in the prehistoric,proto-historic and early historic Eras in a Trans-Polynesian context

This study considers evidence of Māori sex inequality in life chances during the prehistoric, proto-historic and early historic eras in terms of sex differences in bone size and structure, historic reports of sex dimorphism in height, and early census data of ratios of numbers of males to females. The triangulated evidence suggests significant inequality by sex. This evidence is then placed into a contact era Polynesian context. The broader evidence, also triangulated, suggests that sex inequality amongst Māori was not unique in Polynesia. Nor, however, was inequality universal across Polynesia. There are wide differences in sex inequality in different contact-era Polynesian societies. Sex inequality appears to have been less in Tonga, Samoa and Hawai’i than in New Zealand, Tahiti, the Marquesas, Easter Island and the Cook Islands. Sex inequality mostly collapsed by the first third of the 20th century, rendering the cross-island comparisons much more homogeneous.     

One Country Two Peoples?

This article weighs the demographic evidence for either assimilation or separation among Hong Kong residents who were born in British Colonial Hong Kong or Mainland China. Using successive waves of Hong Kong census data from 1991 to 2011, we show the effects of nativity on four indicators of social distance and differentiation: residential segregation, linguistic assimilation, wage inequality and educational opportunity. On the one hand, there is some evidence of assimilation in terms of residential location and home language. On the other hand, in terms of wage inequality and access to postsecondary education, our findings suggest that Hong Kong's population could become more divided depending upon birthplace.     

基于不同区划系统的中国区域经济差异分解研究

基于不同区划系统,采用锡尔系数分解方法来定量测度中国区域经济差异。首先,基于省级空间单元,通过一阶段锡尔系数分析1978年以来中国区域差异的格局及其动态演变;然后,分别基于三大地带--省(直辖市、自治区)--地(市、区、自治州)或者县(市辖区、县级市、县)这两类三级结构的地域行政单元,运用二阶段嵌套锡尔系数分解方法,将差异进一步分解至省内差异水平上,由此揭示出不同于省际分析的区域经济差异特征:省内差异是全国总体差异的重要组分,对于总体差异的影响较地带间差异和省间差异显著得多。     

Income inequality across Canadian provinces in an era of globalization: explaining recent trends

In this article, I use panel data methods to investigate possible factors influencing recent trends in income inequality across Canadian provinces. The ratio of the income share of the highest-to-lowest quintiles and the Gini coefficient of total income are used as measures of inequality. Both point to rising levels of inequality from 1981 to 1999, especially during the 1990s, and the estimation results suggest that several factors have had significant effects on such an increase. In particular, an increase in international trade, technological change, educational heterogeneity, and the unemployment rate are found to contribute to greater inequality. Deindustrialization and declining government transfer payments to persons are also factors explaining the rise in inequality. In contrast, an increase in the female labour force participation rate appears to have dampened inequality. There is also some evidence of a negative association between de-unionization and inequality while no significant association is found between inequality and other demographic shifts, such as immigration and the share of the population over the age of 65.
