How do birth, death, fertility, and migration rates affect population size? What factors can affect these rates?

- 2can some explain to me how birth, death and migration rates affect the population
can some explain to me how birth, death and migration rates affect the population? I have read but really do not understand it? the factors that can affect these rates i am assuming is urbanization cost of raising and educating children educational and employment opportunities for women infant mortality rate average age at marriage pensions abortions birth control religious beliefs some of the affects for death is labor shortages and increased health care burdens any help not to good on all these science terms so i quess this why i am having a hard time understanding how they affect the population?

How do birth affect population size? The more births a society has, the more people it has. For further reading: http://en.wikipedia.org/wiki/Population_growth

- 4Then the mortality rate, birth rate, and migration rate are calculated for a certain town, it is found that the population increases at 8% per annum
Then the mortality rate, birth rate, and migration rate are calculated for a certain town, it is found that the population increases at 8% per annum. If the population is 60,000 today, calculate the population five years ago.

in 1990 the birth rates for whites were 75.6%
in 2000 it was 71.6%
in 2025 it exce

- 8Starting with a hypothetical population of 14,000 people and an even age distribution (1,000 in each age group from 1-5 to 66-70 years), assume that the population initially has a total fertility rate of 2.0 and an average life span of 70 years
Exercise 2. Starting with a hypothetical population of 14,000 people and an even age distribution (1,000 in each age group from 1-5 to 66-70 years), assume that the population initially has a total fertility rate of 2.0 and an average life span of 70 years. Using the spreadsheet for exercises 1-3, estimate how the population will change from this generation to the next under each of the following conditions. a. Total fertility rate and life expectancy remain constant. b. Total fertility rate changes to 4.0; life expectancy remains constant. c. Total fertility rate changes to 1.0; life expectancy remains constant. d. Total fertility rate remains at 2.0; life expectancy increases to 100. e. Total fertility rate remains at 2.0; life expectancy decreases to 50. F. Total fertility rate changes to 4.0; life expectancy increases to 100. Most developed countries have infant mortality rates of around 5 deaths per thousand live births, and some developing countries have infant mortality rates exceeding 100 deaths per 1,000 live births. How would either of these rates affect our final populations? Use a speadsheet.

- 11birth and death model
Each individual in a biological population is assumed to givebirth at an expoenetial rate λ and to die at an exponentialrate μ. In addition, there is anexponential rate of increaseθ due to immigration. However, immigration is not allowed whenthe population size is N or larger.(a) Set this up as a birth and death model(b) If N=3, 1=θ=λ, μ=2, determine theproportion of time that immigration is restricted.
