If there is significant migration in or out of the country, that must be taken into account as well. It is associated with urbanisation and growth and occurs in four phases: By coercive population control prior to the human population exceeding the carrying capacity of the Earth. Help with Questions in Advanced Placement (AP). 1. China is expected to have a zero population growth rate by 2030. Save. c.)the crude death rate is higher than the crude birthrate. Zero population growthThe so-called replacement rate is about 2.2 births per fertile woman. Growth, the increases in cell size and number that take place during the life history of an organism. Zero population growth (ZPG) occurs when births plus immigration in a population just equal deaths plus emigration. This results in very little change in the overall population numbers. By the voluntary action of all of humanity prior to the human population exceeding the carrying capacity of the Earth. & Lytwak, Edward P. “Zero Growth of the Population of the United States.” (, Wooldbridge, Frosty (27 Feb 2013). Zero population growth occurs when a population has the same number of individuals entering the population (births) as those leaving the population (deaths). Answer: c 5. Question: Question 4 Of 19 3.0 Points Density Independent Growth Occurs When: O A. Zero population growth (ZPG) occurs when a country’s birth rate and death rate are roughly equal. Reduced inequalities 11. Zero population growth (ZPG)- occurs when the per capita birth and death rates are equal (r=0) Exponential population growth- aka geometric population growth. Zero population growth occurs when a population has the same number of individuals entering the population (births) as those leaving the population (deaths). 19. The logistic growth refers to a population growth whose rate decreases with the increasing number of individuals and it becomes zero when the population becomes its maximum. Voluntarily limit births and immigration to achieve zero population growth; Continue on the present path until the population is so large that draconian measures become necessary to stop the growth of population; Do nothing and let nature stop the growth through disease, starvation, war, and pestilence. If any group or even if a single-family failed to control its population the entire program would fail. Zero population growth occurs when a population has the same number of individuals entering the population (births) as those leaving the population (deaths). Zero population growth, sometimes abbreviated ZPG (also called the replacement level of fertility), is a condition of demographic balance where the number of people in a specified population neither grows nor declines, considered as a social aim by some. This was mostly the result of China's economic growth and increasing living standards which led to the decline. d.)the total fertility rate falls below the crude birthrate.

That "extra" 0.2 people is what's needed to account for premature deaths -- deaths that occur before procreation. There are two categories of limiting factors— density-independent factors ; density-dependent factors. Sustainable cities and communities 12. 10.The highest population growth rates occur in a few "hot spots" in the developing world, such as sub-Saharan Africa and the Middle East, where economics, politics, religion, and civil unrest keep birth rates high and contraceptive us low. )the crude birth and death rates are simultaneously low. Thus, zero population growth occurs when birth and death rates are equal. Web. Unstable rates can lead to drastic changes in population levels. There occurs a typical fall in death rates and birth rates due to improved living conditions leading to low population growth, a phenomenon called demographic transition.
