Demographic targeting is a form of behavioral advertising in which advertisers target online advertisements at consumers based on demographic information. [1]They are able to achieve this by using existing information from sources such as browser history, previous searches as well as information provided by the users themselves to create demographic profiles of consumers.
As a consequence, it is an interdisciplinary concept, but maintains biological roots. The hierarchical organizations that are inherent to both biology (cell, organ, individual) and demography (individual cohort, population) form a chain in which the individual serves as the link between the lower mechanistic levels, and the higher functional ...
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 ...
Demographic engineering is deliberate effort to shift the ethnic balance of an area, especially when undertaken to create ethnically homogeneous populations. [1] Demographic engineering ranges from falsification of census results, redrawing borders, differential natalism to change birth rates of certain population groups, targeting disfavored groups with voluntary or coerced emigration, and ...
Whether migration increases population fitness will depend if the genes brought in are adapted to local conditions and if they decrease levels of inbreeding in the target population. An Introduced individuals can also positively or negatively affect genetic rescue through behaviors such as mate choice , dominance hierarchies, and infanticide.
A 1982 study by Templeton and Johnson showed that in a population of Drosophila mercatorum under K-selection the population actually produced a higher frequency of traits typically associated with r-selection. [37] Several other studies contradicting the predictions of r/K selection theory were also published between 1977 and 1994. [38] [39 ...
[16] For example, in a closed system where immigration and emigration does not take place, the rate of change in the number of individuals in a population can be described as: = = = =, where N is the total number of individuals in the specific experimental population being studied, B is the number of births and D is the number of deaths per ...
In population dynamics and community ecology, recruitment is the process by which individuals are added to a population. [1] Successful recruitment is contingent on an individual surviving and integrating within the population; in some studies, individuals are only considered to have been recruited into a population once they've reached a certain size or life stage.
