Abstract Functional Urban Areas (FUAs) leads to a better knowledge of urban spatial organisation, which may play a significant role in regional policy making and may be helpful in understanding the connection between urbanisation and demographic development. An explanation of population change in urban regions can be associated the second demographic transition comprising fertility decline below replacement level and postponement of births. The aim of this paper is to focus on establishing similarity patterns and anomalous values of selected demographic variables in the cores and peripheral areas of Functional Urban Areas. At the background of this study lies an assumption that population development of FUA's is shaped by different factors connected with second demographic transition and migrations. To achieve the aims the following demographic characteristics were used: population growth rate, dependency ratio, rate of natural increase, the net migration rate, and the dynamic economic ageing index, Spatial methods play an increasingly important role in contemporary socio-demographic research. In order to identify spatial systems Global Moran Statistics and the Local Indicators of Spatial Association (LISA) including Local Moran statistics as well as Getis-Ord Gi* statistics were used. The research showed global and local autocorrelation of demographic processes in Functional Urban Areas in Poland, namely population growth, natural increase, net migration and population ageing. The use of local Moran's I statistic and the Getis-Ord Gi* method has led to identification of spatial clusters and dispersions representing different demographic variables. Spatial autocorrelation methods can be useful in an analysis of demographic variables including changes in time. The main contribution of this study to the research on demographic processes in urban areas was an application of spatial groupings techniques not only to find out similarity and dissimilarity patterns of demographic indicators but also to apply this findings for the needs of spatial planning.

Abstract The evolution of population distributions in the Krakow Metropolitan Area (KMA) in Poland is subject to analysis in this contribution. Changes and recent reversals in the relationships between the main components of total population growth (natural increase and net migration) are examined in order to determine the level of development of suburbanisation processes in zones of the KMA, with the use of the Webb typology. Research was carried out in four time points: 1988, 1995, 2002 and 2012, covering the year just before the collapse of the socialist regime, the first decade of political and socio-economic transition, and the period before and after accession to the EU. The analysis of differentials in natural increase and net migration is conducted within the context of residential suburbanisation in the KMA, using as a background context recent population developments in Poland and Polish cities. Implications for urban policy arising from changes in the spatial concentration of the population in the metropolitan area are discussed.

This study investigates the demographic and health behavior of the Xavante Indians of Mato Grosso State, Central Brazil. Data covering the period 1999 to 2004 was collected using information from household censuses and vital statistics. In addition to standard demographic analyses, survival analysis was carried out. Results show a young age structure, derived from a combination of high fertility rates (7.7 live births per woman) and declining mortality. Mortality rates, especially infant mortality (97 per thousand), remain very high, surpassing regional and national rates. Natural increase is the main contributing factor to population growth. The annual population growth rate is 4.4%. Results suggest that recent declines in mortality and fertility may be related to transformations in the implementation of basic health care services and internal diversity, the latter of which seems to be associated with local history and sociocultural determinants.

Whereas throughout most of the world the results of the 1953 censusregistration of Communist China, reporting a population of 582·6 million, evoked anxiety and even alarm, the Communists expressed only pride and overwhelming confidence. As a people “liberated from the oppressive chains of capitalism,” Communist leaders felt that their horizons were unlimited and that feeding and caring for a population of this size presented no problems under a system in which people are “the most precious of all categories of capital.” The simultaneous release of vital rates which indicated a birth rate of 37 per thousand population and a death rate of 17 per thousand, further stressed the “great vitality of the people of new China.” The 2 per cent, natural increase (excess of births over deaths), resulting in an annual population growth of some 12 million, was declared, in line with Marxist doctrine, to be an asset in a country with vast new lands and unexploited natural resources, where additional people create additional wealth.

Population Size Change

The aim of this study is to discuss changes in thepopulation and indicate the main reasons of these changes inrural areas of West Pomeranian voivodeship. The study wasconducted on the local level and based on Central StatisticalOffice data from the years 2010 to 2014. In the first part ofthe research, main demographic information is discussed. Itincludes population density, natural increase per 1000 populationand net migration per 1000 population in rural areasof West Pomeranian voivodeship. In the next part of the research,the average population growth rate was counted in theyears 2011–2014. Based on these changes, researched unitswere divided into four groups – two groups with positivechanges and two groups with negative changes. Subsequently,the main reasons of the changes in population size were analyzedin particular groups including natural increase, migration,population structure by age, level of unemployment andentrepreneurship. All indicators were designated as averagesfrom 2011 to 2014. According to the results in most of the researchunits, the net migration determined the population size.The net migration was characterized by higher absolute valuesthan natural increase. The population size changes are relatedto density. The lowest density areas are more depopulated.Moreover, the population size changes are positive related tothe level of entrepreneurship and negative related to the levelof unemployment.

The City

We examine New York’s components of population change—net migration and natural increase—by race and space to explain increases in integrated and minority neighborhoods, in this era of greater ethnoracial diversity. The city has net outflows of Whites, Blacks, and Hispanics, and net Asian inflows, a new dynamic that has reordered its neighborhoods. Asians, often joined by Hispanics, moved into White neighborhoods without triggering White flight, resulting in integrated neighborhoods without Blacks. These neighborhoods constitute a plurality, furthering Black exclusion. Minority neighborhoods saw net outflows, an overlooked phenomenon, but expanded thanks to natural increase, which maintains the existing racial structure. White inflows have helped transition some minority neighborhoods to integrated areas, though integrated neighborhoods with Blacks declined overall. As Asians and Hispanics occupy historically White spaces, this warrants a reconceptualization of race and the emerging racial hierarchy, and a focus on the gatekeeper role of Asians and Hispanics.

Abstract Global amphibian decline is a subject of great conservation concern, yet often basic demographic information is absent, which prevents the understanding of population trends and the planning of effective conservation management. We analysed capture-mark-recapture data from six populations of the endangered Bombina pachypus in order to understand the relative contribution of survival and recruitment to population growth, and to assess if any differences exist among populations in terms of their population dynamics. We found that survival was rather high and generally constant among sites, and recruitment was low, with the exception of two single years at one site. Population growth depended on survival on all sites, except the years following high recruitment at one site. Annual population size was generally lower than 30 individuals, but in one site it was estimated to be larger than 50. Our findings suggest that juvenile survival is more important for population dynamics than recruitment from the larval to the juvenile stage. We also suggest that the low recruitment rates we recorded was a result of juvenile dispersal, and that when populations exhibited high recruitment it was due to occasional successful migration or local recruitment. This pattern could represent a way to counterbalance the risk of inbreeding in populations composed of few individuals, a common characteristic of populations of B. pachypus. Finally, we suggest that conservation measures for B. pachypus should be planned at the landscape scale, and should not be limited solely to the breeding site and its close surroundings.

Urban Population Growth

The central focus of this chapter is to analyse the urban population growth–urban management nexus in Zimbabwean cities. These cities are registering rapid population growth rates, due mainly to massive rural to urban migration and natural increase. Ideally, rapid urban population growth rates should be proportionate to urban infrastructure, facilities and services. This is not in the case in Zimbabwean cities, where the development of informal settlements, rising urban poverty, dilapidated urban infrastructure and other urban developmental challenges are rampant. Drawing from Malthusian theory, the current conditions in Zimbabwean cities represents that stage where the positive and negative checks are expected. In putting together this chapter, we used archival sources such as newspapers, government reports and other secondary sources. We conclude that planning initiatives and population control measures need to be used in Zimbabwean cities to address inefficiency and urban management challenges, which may be compromising urban sustainability. This study provides evidence-based information that urban local authorities may use to formulate policies to manage urban problems.

AbstractThis paper addresses itself to the study of population growth of the small towns in Libya. The Libyan small towns have grown rapidly and it is expected that the majority will continue to grow in the future. Their growth can be attributed to natural increase, internal migration, the influx of foreigners, all of which have been stimulated by the State.
