Well for example, in the USA, for when one person dies 4 are born and statistically at least 4 migrant families a day come in! So the population becomes more dense, as for England when one dies 2 are born and with an average of 1.75 migrants entering the UK on a dailybasis.
A census is a count of a population in a specific region at a particular time. It typically happens every 10 years in many countries to gather information on the demographic, social, and economic characteristics of the population.
When the death rate is higher than the birthrate, the population begins to decline. This can lead to an aging population, reduced workforce, and potential strain on social services and healthcare systems. It may also impact economic growth and development in the long term.
In a colonizing population, genetic diversity tends to decrease as individuals interbreed with one another. This can lead to the loss of some genetic variation present in the original population. Over time, adaptations to the new environment may arise through natural selection, leading to the population becoming more suited to its new habitat.
A change in the prey population effects the predator population because if there are alot of preys, then the predators would eat the preys and the population of predators would increase. But on the other hand, if there are not enough preys, the predators would starve and die which would decrease the population of predators.
The US Census happens once every ten years. The next one will happen in 2010.

When a population overshoots carrying capacity, there is usually a decline in resources leading to increased competition, which can result in high mortality rates, decreased birth rates, and emigration. As the population recovers and stabilizes, there is typically a period of slow growth as individuals compete for resources, which eventually leads to a balance between available resources and population size.
Usually yes, but you do have to take migration, immigration into account.
the density increases
why do density currents hapen?
the density decreases
The density goes down.
In the world of wildlife biology, density dependence is a term to describe something where the the size of the population (or density) is what impacts environmental/habitat/ecological factors. Essentially, it's nature's way of making sure that a population doesn't just keep growing and growing indefinitely. Some of the most obvious density dependent factors are food supply, parasites, living area, competition (for mates, for example), predation, and disease.An easy way to think of it is just think how much something happens to a population because of the density and size of the population - they are related. Whereas, with density independent factors (like a flood), the size of the population doesn't matter because - big herd or little - they are all impacted geographically.
What happens is that you can see that the density of a nail is more than the density of water and that the density of a cork is less than that of water.
according to science and the land use of iberia appariently the density and distribution are ...please wait the following web page hasn't yet loaded ok the page is back the answer happens to be 46745-563249
The density decreases.
The density increase.
