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.

Unreferenced date March 2008 In applied probability , a population process is a Markov chain in which the state of the chain is analogous to the number of individuals in a population 0, 1, 2, etc. , and changes to the state are analogous to the addition or removal of individuals from the population. Although named by analogy to biology biological populations, population processes find application in a much wider range of fields than just ecology and other biological sciences. These other applications include telecommunication s and queueing theory , chemical kinetics and financial mathematics , and hence the population could be of packet switching packet s in a computer network , of molecule s in a chemical reaction , or even of units in a stock market index financial index . Population processes are typically characterized by processes of birth and immigration, and of death, emigration and catastrophe, which correspond to the basic demography demographic processes and broad natural environment environment al effects to which a population is subject. However, population processes are also often equivalent to other processes that may typically be characterised under other paradigm s in the literal sense of patterns . queueing theory Queues , for example, are often characterised by an arrivals process, a service process, and the number of servers. In appropriate circumstances, however, arrivals at a queue are functionally equivalent to births or immigration and the service of waiting customers is equivalent to death or emigration. Typical population processes include birth death process es and birth, death and catastrophe process es.

A disjunctive population , in ecology , is a colony of plants or animals, whose geographical locus is severed from the continuous range of the bulk of the species distribution. Although a disjunctive population may sometimes occur on an island, ref A.W.D. Larkum, Robert Joseph Orth and Carlos M. Duarte. 2006 ref which creates physical separation via water, a large percentage of disjunctive populations are separated from their main range simply by landmass. In some cases a disjunctive population represents a relatively small outlier population from the main range, but in other cases, such as for the Painted Hunting Dog , Lycaon pictus , the entire population is scattered throughout much of Africa and is intrinsically disjunctive.

refimprove date December 2010 Population mobility , geographic mobility or more simply mobility is a statistic that measures migration within a population. It is most commonly used in demography and human geography , it may also be used to describe the movement of animals between populations. Mobility estimates in the Current Population Survey CPS , produced by the United States Census Bureau , define mobility status on the basis of a comparison between the place of residence of each individual to the time of the March survey and the place of residence 1 year earlier. Non movers are all people who were living in the same house at the end of the migration period and the beginning of the migration period. Movers are all people who were living in a different house at the end of the period rather than at the beginning. Movers are further classified as to whether they were living in the same or different county, state, region, or were movers from abroad. Movers are also categorized by whether they moved within or between central cities, suburbs, and non metropolitan areas of the United States. ref CPS The CPS also includes information on reasons for a move. These include work related factors, such as a job transfer, job loss or looking for work, and wanting to be closer to work. Housing factors include wanting to own a home, rather than rent, seeking a better home or better neighborhood ... status, retirement, or health related moves.

Population biology is a study of populations of organisms, especially the regulation of population size, life history traits such as clutch size, and extinction. The term population biology is often used interchangeably with population ecology , although population biology is more frequently used when studying diseases , viruses , and microbes , and population ecology is used more frequently when studying plant s and animal s. Although Reverend Malthus s book, An Essay on the Principle of Population , dealt only with the economy of human population fluctuations, which he theorized as being related to finite food resources, abundance and decadence, it gave inspiration to Charles Darwin for the theoretical basis of his seminal work, The Origin of Species . cquote In October 1838, that is, fifteen months after I had begun my systematic inquiry, I happened to read for amusement Malthus on Population , and being well prepared to appreciate the struggle for existence which everywhere goes on from long continued observation of the habits of animals and plants, it at once struck me that under these circumstances favourable variations would tend to be preserved, and unfavourable ones to be destroyed. The results of this would be the formation of a new species. Here, then I had at last got a theory by which to work but I was so anxious to avoid prejudice, that I determined not for some time to write even the briefest sketch of it. In June 1842 I first allowed myself the satisfaction of writing a very brief abstract of my theory in pencil in 35 pages and this was enlarged during the summer of 1844 into one of 230 pages, which I had fairly copied out and still possess.
