The Quality of Urban Environments in the Brazilian Amazon

In the Brazilian Amazon during the 1980s,urban population growth outstripped rural growth, andby 1991, most of the region's population resided inurban areas. Much of this urban growth involvedestablishment of unplanned housing with inadequateinfrastructure, which resulted in rising pollution. This paper compares indicators of environmentalquality in urban populations of the Amazon in 1980 and1991, and among different kinds of urban populationsin 1991. The results show that environmental qualityin the region deteriorated during the 1980s as theproduction of and exposure to environmental hazardsrose while resources to ward off hazards eroded. Thefindings also show that environmental quality wasparticularly poor in more rapidly growing urbancenters. The urban Amazon may not afford an adequatestandard of living and this may generate out-migrationfrom the region.

21世纪世界人口面临的主要问题与挑战

人类跨入 2 1世纪 ,在迅速发展经济的同时 ,也面临着一些问题和挑战。世界人口数量急剧增长 ,人口倍增时间大为缩短。人口老化速度加快 ,在 2 1世纪的前 10年 ,世界各国都将出现人口老龄化趋势。随着现代化工业和市场经济的飞速发展 ,全球人口城市化速度日益加剧。同时贫困人口问题困扰发展中国家。人类为了满足自身发展的需要 ,导致自身资源日益减少 ,生态环境日益恶化 ,如不设法采取补救措施 ,将会面临一场生态灾难     

世界人口格局中的中国人口转变及其特点

20世纪 50年代以后的中国人口转变与西方传统人口转变有许多不同之处 ,具有自身的特点 ,即转变的迅速性、控制干预性、不彻底性、不稳定性、不平衡性。把握新时期稳定低生育水平的决定是将我国人口转变进行到底的重要措施和手段 ,是实现人口可持续发展的重要步骤

Assessing the devolution revolution: How accurate are state-level estimates from the current population survey

The devolution of many social policy responsibilities from the Federal government to states has prompted increased interest in state-level measures of need. One data source that could be used to provide more state-level information on a variety of topics is the Current Population Survey (CPS). During the past ten years the CPS has been used to produce state-level estimates on a variety of measures. However, there has been little systematic evaluation of these data. This paper provides measures of accuracy for several state-level estimates derived from the CPS. These include standard errors for single-year estimates, three-year averages, and five-year averages of the March CPS measures; standard errors for three-year averages of 12-month CPS files; and comparison of CPS-based estimates to data from the Decennial Census. The paper also examines the relative accuracy of CPS estimates based on states' size. The information in this study will help analysts better understand the tradeoffs between timeliness and accuracy to be considered when using state-level estimates derived from the CPS.     

青海省人口与可持续发展

本文通过对青海省人口条件, 以及由于人口增长的无限性和生态空间支持能力的有限性而引起的两个重大矛盾： 一个是人口再生产物质资料再生产之间不平衡不协调、一个是人口———资源———环境之间原有的生态平衡受到破坏的分析, 指出了青海省国民经济发展必须把各项经济指标与人口的有关指标相结合,形成一个有机整体, 只有这样本省经济才可能得到持续发展,并针对此提出若干措施     

Demographic Differentials and Demographic Integration of Turkish and Kurdish Populations in Turkey

The objectives of the study are threefold: (1) to provide estimates of the total populations and spatial distributions of different language groups in Turkey, (2) to test whether the commonly held belief that Turkish-speaking and Kurdish-speaking populations are “actors” of different demographic regimes is true, and (3) to assess whether a process of integration, in the form of intermarriage of Turks and Kurds is under way in Turkey. Data come mainly from the 2003 Turkish Demographic and Health Survey (TDHS-2003). Based on the assumption that the mother tongue composition of women is also representative of that of the whole population, the results of the TDHS-2003 imply that of the population of Turkey, 83% are Turkish-speaking, 14% are Kurdish-speaking, 2% are Arabic-speaking and the remaining 1% belong to other language groups. Results show that despite intensive internal migration movements in the last 50 years, strong demographic differentials exist between Turkish and Kurdish-speaking populations, and that the convergence of the two groups does not appear to be a process under way. Turks and Kurds do indeed appear to be actors of different demographic regimes, at different stages of demographic and health transition processes.
