The Demography of the World Population from 1950 to 2100. Data source: United Nations — World Population Prospects 2017. Demography (from Ancient Greek δῆμος (dêmos) 'people, society' and -γραφία (-graphía) 'writing, drawing, description') [1] is the statistical study of human populations: their size, composition (e.g., ethnic group, age), and how they change through the ...
This association had been noted by a number of historians, but had not yet been systematically explored in the context of global demography and the history of revolutions and civil war. The structural-demographic theory emerged from his attempts to apply the insights of political demography to the study of revolutions in world history. [9]
An example of this is the "Evolutionary Demography Society", formed in 2012/2013 to increase opportunities for inter and multidisciplinary approaches to understanding how life history and ageing are related and lead to different population demographics.
The use of different algorithms leads to different results, but there is no single best approach for selecting the best algorithm, just as no algorithm offers any theoretical proof of its certainty. [1] One of the most frequently used techniques in geodemographic segmentation is the widely known k-means clustering algorithm. In fact most of the ...
Demographic statistics are measures of the characteristics of, or changes to, a population. Records of births, deaths, marriages, immigration and emigration and a regular census of population provide information that is key to making sound decisions about national policy. [1] [2] A useful summary of such data is the population pyramid. It ...
the simple description of the location of population numbers and characteristics; the explanation of the spatial configuration of these numbers and characteristics; the geographic analysis of population phenomena (the inter-relations among real differences in population with those in all or certain other elements within the geographic study area).
Historical demography is the quantitative study of human population in the past. It is concerned with population size, with the three basic components of population change (fertility, mortality, and migration), and with population characteristics related to those components, such as marriage, socioeconomic status, and the configuration of families.
In demography, demographic transition is a phenomenon and theory in the social sciences referring to the historical shift from high birth rates and high death rates to low birth rates and low death rates as societies attain more technology, education (especially of women), and economic development.
