The rate at which population size grows or declines depends on the rate of what?
births, death, immigration and emigration
What does it mean if a population is in equilibrium?
The birth rate and the Death rate are equal, providing there is no immigration/emigration of the population.
How do birth rate and death rate affect a country's population?
If the birth rate is higher than the death rate, the population increases. If the death rate is higher than the birth rate, the population decreases.
When the death rate is higher than the birthrate?
The population decreases when the death rate is higher than the birthrate.
Why can't a vertical line be used to represent rate of change?
the rate of change is related to the slope; the higher the slope, the higher the rate. If the line is vertical, that is infinite slope or infinite rate of change which is not possible
Which is higher Spain's rate immigration or emigration?
immigration
Formula for net migration?
immigration rate + emigration rate.
What were the causes for the expansion of the population of Bombay?
A higher birthrate than death rate. More immigration than emigration.
How can populations change in size?
Populations can change in size due to factors such as birth rates, death rates, immigration, and emigration. If the birth rate is higher than the death rate and there is more immigration than emigration, the population will increase. Conversely, if the death rate is higher than the birth rate and there is more emigration than immigration, the population will decrease.
What are the four criteria for a population?
Population density, Immigration, Emigration Exponential Growth
How does Immigration and emigration and natality rate and mortality rate affect population?
Immigration and higher natality rates increase population, while emigration and higher mortality rates decrease it. Immigration brings in new individuals, boosting population, while emigration removes individuals, decreasing population. Higher natality rates lead to more births, contributing to population growth, whereas higher mortality rates result in more deaths, reducing the population size over time.
What are four main characteristics of a population?
Birth Rate, Death Rate, Immigration, Emigration
What are four factors that affect the size of population?
1) Death 2) Birth 3) Emigration 4) Immigration
The rate at which population size grows or declines depends on the rate of what?
births, death, immigration and emigration
How do you calculate emigration rate?
You can calculate a country's immigration rate in a manner similar to the calculation of birth and death rates. The immigration rate for Canada is 7/1000 (0.7%)
What are four factors that affect mortality rate?
Immigration, emigration, birth rate, death rate
What situation in which the birth rate plus immigration equals the death rate plus emigration is called?
zero population growth
