Question | Answer |

Professionals who study and make predictions about human populations are called | demographers |
Amount of time it took the population of the Earth to double from 2 million to 4 billion | 44 years |
Factors that contributed most to the exponential growth of the human population | more food, better hygiene |
The distribution of ages in a population at a specific time | a population pyramid |
The result of educating women to learn family-planning technique | lowered birthrates |
Human population growth was most rapid during which period of human history | Modern Age |
A cholera outbreak can be caused this | lack of clean water |
Because birth rates have begun to fall this will occur to the Earth’s population | stabilize somewhere around 9 billion by 2050. |
region experiencing the biggest increase in population | Asia |
Factors which make it difficult to reduce population growth | low literacy and limited healthcare |
a strategy that could increase population growth | limiting education for women |
adequate sewage treatment facilities for growing populations results in this | decrease in waterborne diseases |
When birth rates and death rates are both high this occurs to the population | the population grows slowly, if at all |
The Industrial revolutions effect on the population | increased the human population from 1880-1930 |
combination of high birth rates and low death rates | increased the human population from 1880-1930 |
improvements in societal infrastructure and services | increased the human population from 1880-1930 |
the third stage of demographic transition characteristic | social conditions that favor smaller families |
reason that wood is considered a limited resource in many developing countries | People cut down trees faster than they can grow. |
the rend of the death rate during Stage 2 of a population’s demographic transition | decreases |
Age structure of Countries with high growth rates | more younger people than older people. |
A disease that is often spread through unsafe public water sources | dysentery |
Characteristics that predict population sizes | age structure, survivorship, fertility rate, and migration |
increased immigration | movement of people into an area that can cause a population to increase |
the characteristics of the model of demographic transition | life expectancy, education of women, industrialization |
Less-developed countries suffer more from rapid population growth because they are less likely to have this piece in place that helps to support the population | infrastructure |
The point when world population growth will eventually stop | countries have replacement-level fertility rates |
can result from increased birth rate, increased life expectancy or immigration | increase in population |
the average number of children each parent must have in order to replace themselves in the population | replacement level |
the birth rate drops and the size of the population begins to decrease during this transitional stage | |
fourth stage of demographic transition | |
two revolutions that brought about changes that caused exponential growth of the world human population | industrial and scientific |
A shortage of this can decrease the food supply available to a growing population | arable land |
The study of human population patterns is called | demography |
What countries are to be given priority for foreign aid | least-developed |
One way to stabilize the world population is to reduce these by improving women’s status and educational opportunities | fertility rates |
Most demographers predict a medium population growth rate and a world population reaching this in 2050 | 9 billion |
This helps demographers predict which age groups will experience the most growth | population pyramid |
Type I and Type III survivorship curves indicate populations that are growing in this manner | slowly or not at all |
An adequate supply of fuelwood helps to prevent this by allowing water to be boiled to sterilized | disease |
China has implemented a campaign to reduce birth rates that includes this reward for single-child families | economic rewards |
The theory of demographic transition is based on the idea that industrial development causes this type of progress that affects population growth rates | economic and social |
Local water supplies may be contaminated when they are also used for this type of disposal | sewage |
Continental population that is expected to shrink by the year 2050 | Europe |
Some less-developed countries have tried to move forward in demographic transition by directly reducing these through advertising and economic incentives | birth rates |
The world population will stop growing when fertility rates decline to this | replacement levels |
During the last 200 years, the human population has undergone this type of growth | exponential |
The percentage of members of a group that are likely to survive to any given age | survivorship |
A population with high fertility will have an age structure with a higher percentage of this age group | young people |
Countries experiencing the greatest population growth are most likely to be those going through this | industrial revolution |
Wealthy, developed countries such as Japan and Germany are in the fourth stage of demographic transition, when the population size begins to decline. This state is also known as this | post-industrial |
pre-industrial condition-birth rate and death rate are both at high levels and the population is stable | stage one of demographic transition |
population explosion occurs. Death rates decline as hygiene, nutrition and education improve. Birthrates are still high and population growth is still fast | second stage of demographic transition |
population growth slows because the birth rate decreases-even though the population is much larger it has stabilized | third stage of demographic transition |
The birth rate drops below replacement levels and the population begins to decrease. | fourth state of demographic transition |
type of survivorship curve where people live to be very old | Type I |
type of survivorship where populations have a similar death rate at all ages | Type II |
type of survivorship where populations is a pattern in very poor human populations in which many children die | Type III |
