the Birth Rate is the rate of birth in a population, the death rate is the number of deaths in a population and the growth rate is the growing numbers of the population.
Population growth its that simple
A negative population growth exists
Demograhy only composes of Birth and death ,whereas Vital Statistics studies Marriage and migration along with death and birth for any population
Crude birth rate is how many live children are born. Crude death rate is how many people die. Crude death minus crude birth is the net gain (or loss) and is called the birth rate. It represents whether or not deceased people are "replaced".
The population growth will decline since more people are dying then being born subject to condition that migration factor remains constant
The period between birth and death is: lifetime.
the fitest survive
dead
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.
forever.......till death
Population growth is influenced by the balance of birth rates, death rates, immigration, and emigration. A high birth rate increases the population, while a high death rate reduces it; when birth rates exceed death rates, population growth occurs. Immigration adds to the population, while emigration decreases it. The overall effect on population growth depends on the interplay of these factors; for instance, a country with high birth rates and net immigration will likely experience significant population growth.
There are more people who are born then die.
death rate is subtracted from birth rate.
birth death migration/emigration
Zero growth
The stages that organisms typically go through from birth to death are: birth, growth, reproduction, and death. These stages are part of the life cycle of an organism.
birth rate - death rate = growth rate
