Socio Economic Factors

SummaryThe age structure of the immigrant female population as shown by the 1961 Census was heavily biased towards the young adult age groups, where fertility rates are highest. The birth rate for such a population could be expected considerably to exceed the average for this country as a whole, due to differences in age structure alone. The Census also showed marked differences betwen the fertility rates of different groups of immigrants but suggested that for the most important groups —from the Irish Republic, the Indian sub-continent and the Caribbean—they then amounted to a completed family size of roughly ½ child above the England and Wales average. There were also marked differences in 1961 between the socio-economic structure of immigrant groups; such evidence as there is points to socio-economic factors as playing an important part in explaining the fertility of immigrants, and its possible change over time.

Level Of Understanding

This contribution examines the relationship between local population studies and the national picture by considering the example of the Victorian fertility transition in England and Wales. It begins by summarising the history of research into the fertility decline. It then describes a recent project, the Atlas of Fertility Decline, which has used the newly available machine-readable data on individuals from the censuses from 1851 to 1911 to estimate fertility at the level of the registration sub-district. The results from the project can be used to highlight geographical variations in fertility at the regional and local level. Explaining the patterns observed, though, will require detailed local studies. New resources that are being opened up for researchers interested in such issues in their local community, in their county, in their region or in the nation as a whole, make the pursuit and attainment of answers possible. New light can be thrown on local scenes that will each add a piece of the jigsaw which, when completed, will bring a whole new level of understanding of the complex puzzle that is the fertility transition in England and Wales.

Homosexual Transmission

This paper gives details of a model for forecasting aids, developed for actuarial purposes, but used also for population projections. The model is only appropriate for homosexual transmission, but it is age-specific, and it allows variation in the transition intensities by age, duration in certain states and calendar year. The differential equations controlling transitions between states are defined, the method of numerical solution is outlined, and the parameters used in five different Bases of projection are given in detail. Numerical results for the population of England and Wales are shown.

Future Population

In 1944 the Royal Commission on Population was set up in order to determine the probable consequences of population trends then current. In order to do this they prepared a range of sixteen separate population projections for Great Britain based on various combinations of assumptions as to mortality, fertility (and marriage), and migration. The method used, in which each component of population change i.e. birth, death and migration receives separate treatment, is generally known as the component method. This distinguishes it from cruder methods based on the assumption that the total numbers in a population follow some mathematical formula.Since the Royal Commission reported, this method has continued to be used in preparing what may perhaps be described as the ‘official’ projections of the population of England and Wales.

The subject of this paper is the influence of anthropogenic factors on the state of erosion in the rural part of the municipality of Vozdovac. The aim of the research is the analysis of the influence of the local population on land resources, based on the past and present state of erosion and sediment production, the usage of land resources, as well as natural and mechanical population movements. The municipality of Vozdovac is one of the 17 municipalities in Belgrade area, which covers an area of 15,000 ha. The municipal territory includes both urban and rural parts (9216 ha). When it comes to how land resources are used, it is a characteristic example of erosion processes in the mountainous Belgrade area. This paper presents an analysis of the degree of erosion threat to agricultural land in the municipality of Vozdovac, including three periods (1971; 1988; 2012), where the method used is the erosion potential method by professor Gavrilovic. However, the calculation of sediment yield was made by the method of S. Gavrilovic. The analysis of demographic factors pointed to the influence of anthropogenic factors on the state of erosion. Mathematical methods were used - geometric and exponential progression for population projections in 2020 and 2030. The results of this study showed that the intensity of erosion in that area significantly decreased and that it has a tendency of further decline.
