Introduction:
The birth rate is the number of live births in a particular time and the death rate is the number of the people deceased in a particular time. In humans, it is observed a decrease in the rate of death has been followed by a drop in the rate of birth. The speed of this adjustment contributes to determining future population growth.
Explanation of Solution
The changes in the population are termed as the demographic transition. The growth rate of the population is determined by subtracting the death rate from the birth rate.
In the given graph, in the beginning, the death and birth rates are high and the population growth is constant. Then in the demographic transition, the birth rates remain the same but the death rate falls. Then in the graph, the birth rate drops and the death rate remains constant.

- Visit the website of the Population Reference Bureau, www.prb.org (Links to an external site.). Find the most recent “World Population Data Sheet” under the Data section. Choose two nations to compare with respect to: birth rate, death rate, infant mortality rate, rate of population growth, and/or other data indicators of interest to you. What do these data tell you about the health of the populations of these countries?arrow_forwardA country’s total population divided by country’s total land area of a country = _______arrow_forwardVisit the Gapminder.org website (the same one you used for your Health Systems assignment). Compare the growth rate/ population size to factors that have to do with climate change, such as CO2 emissions, for two different countries. In your post, discuss which factors you chose to review and the results for the two countries (name them!) for comparison. What are the public health implications of this data?

Add the link sources please and thank.arrow_forwardThe following equation is used to calculate the population growth rate, Ro, per generation from a life table. Iy is survival probability from birth to age x and my is fecundity at age x. Ro = Elkm Multiplying ly and my and summing it over all age categories in the life table gives the population growth rate per generation because: Calculating the reproductive output for each age class requires considering the survival probability to that age (a dead individual does not reproduce) and the fecundity at that age by multiplying them with each other. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The fecundity at each age is lower when the survival is higher because of energy constraints. Multiplying probability of survival and fecundity in each age class takes this trade-off into account. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The resulting type of growth…arrow_forward

- The moose population in Northern Alberta is estimated to be around 11, 800. During the year, there were 5054 births, 4567 deaths, 25 immigrations and 52 emigrations. Calculate the per capita growth rate. Express your answer as a value between 0 and 1 rounded to two decimal places. If the population is decreasing indicate this with a negative sign.arrow_forwardA population of rabbits, when introduced to a new environment with abundant resources, would most likely display what type of growth?
