Calculate the growth rate of a population. (class notes)?
birth rate - death rate = growth rate
Population total land area birth rate death rate and population density of china?
The following data gives the population, total land area, birth rate, death ate and the population density of China; Population, total (2010) 1,338,299,512.0 Land area (sq. km) (2010) 9,327,480.0 Birth rate, crude (per 1,000 people) (2009) 12.1 Death rate, crude (per 1,000 people) (2009) 7.1 Population density (people per sq. km) (2010) 143.5
What is a density dependent factor?
The density dependent factor refers to the factors that affect the size or growth of a given population density. The factors also affect the mortality rate and the Birth Rate of a population. Some of the density dependent factors are disease, parasitism, availability of food and migration.
How do you calculate birth rate?
The birth rate is calculated by dividing the number of live births in a year by the total population, then multiplying by 1,000 to express it as a rate per 1,000 people. The formula is: (Number of live births in a year / Total population) x 1,000.
Examples of human-environmental interaction?
EX: Population density; factories; birth rate; death rate; timberline; etc.
Environmental factors that limit population density is?
Just a BASIC few would be; Death Rate, Birth Rate, Migration,
What are the four criteria for a population?
Population density, Immigration, Emigration Exponential Growth
What is population inversion?
Inverse population density is when the population density decreases, the population growth rate also decreases. This is opposite to density dependent because here the population growth rate decreaes as population density increases.
What are population characterists?
Birth rate, Death rate, Immigration, Emigration, geographic distribution, population density, and growth rate. It can also mean what is something that if you saw on a test you would think of population like a group of animals or a group of plants (is describing population).
Relationship between birth rate death rate and growth rate?
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.
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.
What are the four main determiners of population density?
The four main determiners of population density are birth rate, death rate, immigration rate, and emigration rate. These factors influence how quickly a population grows or shrinks within a specific area, impacting the overall population density.
