An analysis of population and social change in London wards in the 1980s   总被引:1,自引:0,他引:1  
"This paper discusses the estimation and projection of small area populations in London, [England] and considers trends in intercensal social and demographic indices which can be calculated using these estimates. Information available annually on vital statistics and electorates is combined with detailed data from the Census Small Area Statistics to derive demographic component based population estimates for London's electoral wards over five year periods. The availability of age disaggregated population estimates permits derivation of small area social indicators for intercensal years, for example, of unemployment and mortality. Trends in spatial inequality of such indicators during the 1980s are analysed and point to continuing wide differentials. A typology of population and social indicators gives an indication of the small area distribution of the recent population turnaround in inner London, and of its association with other social processes such as gentrification and ethnic concentration."  相似文献

Factors affecting regional differences in population growth in the United States are explored. "In this study, we estimated the contributions of births, deaths, and migration to changes in population size between 1950 and 1980 for the 48 contiguous states in the United States. We found that population momentum (i.e., the growth that would occur in a closed population if fertility and mortality rates remained constant) had the largest effect on population growth in most states, but that differences in net migration were the major cause of state-to-state differences in growth rates. We also found that net migration has been gaining in importance compared to natural increase as a component of population growth. We expect this trend to continue in coming decades." This is a revised version of a paper originally presented at the 1988 Annual Meeting of the Population Association of America (see Population Index, Vol. 54, No. 3, Fall 1988, p. 429).  相似文献

Considerations of the compactness and aesthetics of electoral districts have loomed large in the litigation surrounding the last round of US redistricting. For a variety of reasons, we expect that there will be increasing pressure on Canadian electoral cartographers to provide opportunities for protected minorities to be represented in the country's federal legislature. As a result, we expect that future electoral maps may well embody a tradeoff between compactness and other representational and cartographic desiderata. We look for evidence of this in an exploratory analysis of the last two federal electoral maps (adopted in 1987 and 1996) and in so doing we offer the first country-wide assessment of the compactness of Canadian federal electoral districts (FEDs). The results demonstrate the importance of natural boundaries in the achievement of district compactness. Strong evidence of a decline in the compactness of FEDs between the two maps is not forthcoming, however. Thus there is relatively little sign that Canadian electoral districts will be open to the kind of aesthetically-based legal challenges that American Congressional Districts faced in the 1990s. However, the analyses we report establish an important baseline against which the next electoral map, to be produced following the 2001 census, can be compared.  相似文献

The Reagan/Bush Administrations cut back federal support for state and local governments during the 1980s, causing total real resources available to finance local roads and bridges to increase very slowly between 1977 and 1989. The effect of federal aid on spending for infrastructure has been subject to debate for many years. Some studies have indicated that federal aid is stimulative, while others report that federal aid substitutes for local resources. This article examines the effect of state and federal aid on county highway spending. The analysis demonstrates that, in 1987, federal aid was stimulative but state aid was not. In light of changes brought about by the Surface Transportation Efficiency Act of 1991 (ISTEA), we can expect federal aid to have a stronger relationship with local highway spending.  相似文献

Although it is widely recognized that demographic transition is not an uninterrupted process, demographers and population economists have treated short‐term swings in fertility with a measure of curiosity. Iran's experience of population growth after the Revolution in 1979 points to a double paradox of a steep and unprecedented surge in population growth in the 1980s followed by a swift restoration of fertility decline in the 1990s. Both periods have been characterized by extensive socio‐economic and institutional changes combined with radical and far‐reaching sways in Iran's post‐revolutionary population policy. This article applies standardized decomposition analysis to separate out and quantify the proximate components of change in the crude birth rate during these two fertility ‘boom’ and ‘bust’ phases. The aim is to ascertain to what extent structural/demographic or behavioural factors can explain the dynamics of change in fertility and population growth in Iran since the late 1970s. Our findings point to a hitherto neglected role of population momentum in initiating the ‘Islamic baby boom’ as well as a more limited role for population policy in explaining the genesis(rather than the momentum) of both boom and bust phases.  相似文献

After long periods of activism and policy debate, Ontario and Quebec were the first two provinces to integrate midwifery into their health-care services. Despite its success and growing popularity in the post-legislative era, midwifery was a highly contentious policy issue, with debates emerging at every level of policy development. In this essay, the authors explore how these debates played out in media. Specifically, the authors suggest that the frames produced by newspapers during this period served to align midwifery with broader provincial socio-political discourses, which in turn legitimized state intervention in the area of reproductive health. At the same time, however, the authors demonstrate that where Ontario media representations muted differences between midwives and physicians, representations in Quebec emphasized them. Thus, the authors show that in very different ways, media representations of midwifery in Ontario and Quebec both established a discursive context in which the state had to "act on" midwifery and midwives, and also challenged the potential of midwifery to transform women's birth experiences.  相似文献

In the author's view the contemporary detente and the spirit of Helsinki may spread historical optimism like that established after the end of World War I. The likeness of mentality leads to a retreat in fashion everywhere, and archaeology will hardly be an exception. Like some others the author also predicts an archaeological structuralism and considers its possible realization with respect to the ‘damned question’ of archaeology ‐ the change of cultures. There has here been sounded an unexpected call to dig less, and one more expected ‐ to theorize more.  相似文献

论20世纪七八十年代日本的石油危机对策   总被引:3,自引:0,他引:3  
李凡 《世界历史》2003,5(1):40-48
面对突如其来的石油危机 ,日本首先在对外政策上采取稳住石油供应对策 ,放弃对阿以冲突的“中立”政策 ,采取支持阿拉伯国家的“亲阿拉伯”政策 ,加强同中东产油国关系。随着石油危机的缓解 ,日本又积极开展国际合作 ,与西方石油消费大国共同合作避免石油危机再度袭来。与此同时 ,日本在对内政策上大力开展调整主要产业结构对策 ,放弃以重化学工业为主的产业结构 ,发展低能耗、高科技产业 ,力争从根本上摆脱石油危机的困扰。  相似文献

The 2008 financial and economic crisis has led to widespread destruction of employment in Spain. Using municipality data, I examine employment growth differences between urban cores, urban hinterlands, and rural areas during the pre‐crisis period and the recession period. The data show that patterns of growth and decline have been very uneven across different types of areas. While in the boom years, hinterlands and rural areas experienced higher growth, urban core areas have done better during the recession years. I then test three strands of explanations for local growth differences: (i) the role of the local sectoral composition, (ii) the role of human capital, and (iii) the role of access to urban core areas. Estimations for employment growth in the two periods show that the crisis has altered some of the drivers of local employment growth and that human capital has been a key determinant of local resilience during the Great Recession.  相似文献
