The WorldPopulation Foundation WPF was founded in 1987 in the Netherlands by Diana and Roy W Brown . Their purpose was to create an organisation to draw attention to the effects of high birth rate s and rapid population growth on maternal mortality maternal and infant mortality , communities and the environment, and to raise funds for population projects and programmes, with the ultimate aim of reducing world poverty and improving the quality of life of the world s poorest people. From 1987 until 1994, WPF was a small organisation mainly supported by donations from the founders and by consultancy assignments. In 1994, the WPF played an important role in the Dutch delegation of the International Conference on Population and Development in Cairo, Egypt . At this conference, the Cairo Programme of Action was adopted which still serves as a foundation for WPF s work. WPF works to reduce maternal and infant mortality, and improve sexual health and reproductive rights . It acknowledges that attention for these themes and to the improvement of services will contribute to the struggle against poverty worldwide. Therefore WPF advocates the implementation of these themes in the UN s Millennium Development Goals . 2006 2009, the WorldPopulation Foundation s board members include Nafis Sadik , former Executive Director of UNFPA .

It is the study of the ways in which spatial variations in the distribution, composition, migration, and growth of populations are related to the nature of places. Population geography involves demography in a geographical perspective. It focuses on the characteristics of population distributions that change in a spatial context. Examples can be shown through population density maps. A few types of maps that show the spatial layout of population are choropleth , isoline , and dot maps. Population geography studies Demographic phenomena natality, mortality, growth rates, etc through both space and time Increase or decrease in population numbers The movements and mobility of populations Occupational Structure The way in which places in turn react to population phenomena e.g. immigration Research topics of other geographic sub disciplines, such as settlement geography , have also a population geographic dimension Grouping of people in settlements The way from the geographical character of places e.g. settlement patterns All of the above are looked at over space and time.
