Population Clock. Population Distribution Population distribution means the pattern of where people live. World population distribution is uneven.

Population density in agriculture : standing stock or plant density is a measurement of population per unit area, or exceptionally unit volume; it is a quantity of type number density. It is frequently applied to living organisms , most of the time to humans.

As in other parts of Africa, the population of Senegal has been increasing rapidly over the past several decades. This chapter traces the growth and distribution of the population of Senegal over the last 30 years and discusses briefly both interregional and international migration. From administrative counts, which probably underestimate the true size of the population, it is estimated that Senegal's population increased from about 1.

What factors affect population density and distribution?

Current population growth is being accompanied by a significant change in human habitat. As an increasing number and fraction of the global population live in urban areas, the physical environment inhabited by humans is rapidly changing. This change is likely to influence both human populations and the ecosystems where the populations are concentrated. The global population growth rate is currently decreasing, but demographic momentum implies that population growth will continue, according to most forecasts, until at least the year O'Neill and Balk, At the same time, widespread urbanization has the effect of concentrating the growing population into dense settlements at unprecedented rates Meyer and Turner, This represents a relatively recent change of physical habitat for humans as well as a change in the nature of human impact on specific ecosystems.

Population density methods provide promising time-saving alternatives to direct Monte Carlo simulations of neuronal network activity, in which one tracks the state of thousands of individual neurons and synapses. A population density method has been found to be roughly a hundred times faster than direct simulation for various test networks of integrate-and-fire model neurons with instantaneous excitatory and inhibitory post-synaptic conductances. In this method, neurons are grouped into large populations of similar neurons. For each population, one calculates the evolution of a probability density function PDF which describes the distribution of neurons over state space. The population firing rate is then given by the total flux of probability across the threshold voltage for firing an action potential.

Population distribution is a term used to describe how humans are spread across the Earth. Population distribution across the Earth is uneven. Some areas are densely populated, whereas others are sparsely populated. Areas with extreme climates such as hot and cold deserts make it difficult to grow crops and access water. Regions with dense vegetation cover, such as rainforests, provide challenges in terms of access and the lack of services make human inhabitation very difficult. Locations that regularly experience natural hazards can discourage people from settling in the area.

Global Population Distribution and Urban Land Use in Geophysical Parameter Space

Character of population distribution is one of the focuses studied by urban geography. Using the fifth national census data as basic data and using areal interpolation method, this paper analyzes character of urban population distribution of Shenyang City, Northeast China, in terms of three aspects of statistical character, spatial auto-correlation and spatial structure. Furthermore, this research analyzes the factors affecting the population distribution of the city. The main conclusions include: 1 There is an obvious structure character of population distribution in the grid with a grain of m, which is appropriate scale when researching population distribution in Shenyang City. Spatial heterogeneity of population density is low. Population density distribution has multi-cores character.

Сколько я уже тут кручусь. Однако считать ему не хотелось. По профессиональной привычке поправив съехавший набок узел галстука, он повернулся к писсуару. Он подумал, дома ли Сьюзан. Куда она могла уйти. Неужели уехала без меня в Стоун-Мэнор.

 Так вы гражданин Канады. - Разумеется. Как глупо с моей стороны. Прошу меня извинить. К человеку в моем положении часто приходят с… ну, вы понимаете.

 - Надо думать. Есть различие, которое мы все время упускаем. Что-то очень простое. - Ой, дорогие мои… - сказала вдруг Соши.

 Агент Смит, - произнес он медленно и четко, - мне нужен предмет. Лицо у Смита было растерянным. - Сэр, мы до сих пор не имеем понятия, что это за предмет.

Беккер вышел из телефонной будки на перекрестке калле Саладо и авениды Асунсьон. Несмотря на интенсивное движение, воздух был наполнен сладким ароматом севильских апельсиновых деревьев. Спустились сумерки - самое романтическое время суток. Он подумал о Сьюзан. Но тут же в голову пришли слова Стратмора: Найдите кольцо. Беккер в отчаянии плюхнулся на скамейку и задумался о том, что делать .

У нас тут творятся довольно странные вещи. Я хотел спросить… - Черт тебя дери, Джабба! - воскликнула Мидж.  - Именно это я и пыталась тебе втолковать. - Возможно, ничего страшного, - уклончиво сказал он, - но… - Да хватит. Ничего страшного - это глупая болтовня. То, что там происходит, серьезно, очень серьезно.

У тебя ужасный вид. Сьюзан подавила поднимающуюся волну страха. В нескольких метрах от нее ярко светился экран Хейла. - Со мной… все в порядке, - выдавила. Сердце ее готово было выскочить из груди.

 Здравствуйте, Это Сьюзан Флетчер. Извините, меня нет дома, но если вы оставите свое сообщение… Беккер выслушал все до конца. Где же. Наверняка Сьюзан уже начала волноваться.

Когда Мидж проходила мимо, Бринкерхофф по выражению ее глаз понял, что она и не думает сдаваться: чутье не позволит ей бездействовать. Бринкерхофф смотрел на массивную фигуру директора, возвышающуюся над письменным столом.

 Хорошо. Давайте попробуем.  - Он потянулся к клавиатуре.  - Мистер Беккер, пожалуйста, продиктуйте надпись. Медленно и отчетливо.

Вниз. Скорее. Еще одна спираль.

Apart from physical factors several social, demographic, economic, political and historical factors affect population distribution. In the case of Cambodia, civil unrest.
