simple thing.. no of death is equal to 4 times larger than the no of birth....
There is a change in population.
When the death toll and birth rate of people are equal around the world.
It doesn't change.
In a photostationary state, a balance is achieved between photochemical reactions, where the rate of formation and loss of species involved in the reaction are equal. This state is reached under the influence of light. In contrast, an equilibrium state is reached when the forward and reverse reaction rates are equal, irrespective of the presence of light.
The model of population growth that states the growth rate remains constant because birth and death rates are equal is called zero population growth or ZPG. In this scenario, the population size does not increase or decrease over time due to the balance between births and deaths.
Belgium is more an medc, because it is well economically developed and the birth and death rate are equal
The birth rate is 42.99 births /1,000 people The death rate is 11.04 deaths / 1,000 people (Figures according to 2011 estimates by CIA World Factbook)
Expansive population pyramid: wide base and narrow top, indicating high birth and death rates. Constrictive population pyramid: narrow base and wider top, showing low birth and death rates. Stationary population pyramid: nearly equal widths at all age groups, suggesting stable birth and death rates.
In demographics stationary population is when the death rate and birth rate are equal therefore the population is neither decreasing or increasing but it is stationary.
In free fall, when the air resistance is equal to the weight of the falling object, we say that the object has reached ________ velocity.
