If the population growth rate becomes zero the population size becomes static. It stays where it was when it became zero until the rate changes. If the rate becomes negative the population would begin to shrink.
Population growth in which the growth rate decreases with increasing number of individuals until it becomes zero when the population reaches a maximum.
Population growth is negative when birthrate is less than death rate.
If immigration and emigration numbers remain equal, the most important contributing factor to a slowed growth rate would likely be a decrease in the birth rate of the population. With births being the primary driver of population growth in this scenario, a decline in the birth rate would result in a slower overall growth rate.
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.
Its maintained by its birthrate and mortality rate. As long as the 2 are equal the population will be equal and if one is greater than the other the scale is tipped.
the population growth rate in russia is 0.5%
The population of Zambia is 12,309,466 The population growth rate is at 3.03%.
As of 2011, the population growth rate of Ghana is 1.787%.
The population growth rate of Europe is currently at about -2%.
Mexican population growth rate is 1.21% (2014 est.)
the UK's population is 62,698,362 million and the growth rate is 0.557%
When the death rate and the birth rate are equal. This basically means that the amount of people that are dying are being replaced by babies being born. But no extra babies are being born so there is no population growth.
