Zero Population Growth means that as many people are born as will die in a given year. This is difficult to achieve, because every improvement in health care and medical processes will both extend life span of the elderly who were about to die AND will increase the health of mothers and newborn babies, both of which will disturb the ZPG balance. So it's a probability process, and since none of this stuff is really under anyone's control, it's hard to manage.
It means the population is not growing or declining.
Zero population means that there is no growth in the number of people or animals or plants in an area. The number of deaths equal the number of births.
On a graph of population growth the size of the population when the growth rate decreases to zero represents an area's carrying capacity.
In a country with zero population growth, you would expect to find a stable population size where the number of births equals the number of deaths. This would mean the population is not increasing or decreasing over time.
Zero population growth is a sign of a low birthrate. Other factors that affect population growth include a stagnant Death Rate and a low mortality age.
A positive growth ratio (or rate) indicates that the population is increasing, while a negative growth ratio indicates the population is decreasing. A growth ratio of zero indicates that there were the same number of people at the two times
Is Zero Young Population Growth , because the cost of their lifes increase a lot
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.
well when you think about it you can stop cheating and look at a book for once....
France. It's not increasing but it's not decreasing.
Population growth in which the growth rate decreases with increasing number of individuals until it becomes zero when the population reaches a maximum.
