This demographic balance could occur when the birth rate and death rate are equal. … Therefore, a country that has reached zero population growth has a
population where births plus immigration is equal to deaths plus emigration over the course of a year
.
What does it mean when there is zero population growth?
Definition: Zero population growth (ZPG) is
the absence of population growth in which equal birth and death rates create a stable human population
.
Why do you think some countries such as Italy have reached zero population growth?
Many European counties, such as Italy, have reached zero or negative population growth because
their birth and death rates are about the same, or death rates are higher
. … Death rates are relatively low in many of the countries with high birth rates because the majority of the population is young.
Where is a country’s zero population growth likely to be?
economically developed
. A country with zero population growth is likely to be economically developed.
What countries have zero or negative population growth?
Examples of countries experiencing negative population growth include the
Ukraine, Russia, Belarus, Hungary, Japan, Italy, and Greece

pyramidal structure
, but with many fewer young and reproductive-aged individuals and a greater proportion of older individuals. Other developed countries, such as Italy, have zero population growth.
What does it mean for a population to be in exponential population growth?
In exponential growth,
a population’s per capita (per individual) growth rate stays the same regardless of population size
, making the population grow faster and faster as it gets larger. In nature, populations may grow exponentially for some period, but they will ultimately be limited by resource availability.
When a population reaches its carrying capacity?
If a population exceeds carrying capacity,
the ecosystem may become unsuitable for the species
to survive. If the population exceeds the carrying capacity for a long period of time, resources may be completely depleted. Populations may die off if all of the resources are exhausted.
