Geographical Analysis of Population - AP Human Geography

In 2013, Mexico was the birthplace of the largest share of the United States of America's foreign born immigrant population, accounting for almost one-fourth of America's total foreign-born population.

This population pyramid would portrays the population of a college town. The large population within the 20 to 30 population group shows the presence of a university. A retirement community would have almost no one under the age of 55. Populations with high birth rates have pyramids with large bases, while populations with low birth rates are shaped like rectangles.

College towns have a higher population of males and females around the age of 20. There will be other age groups living in the town, but most of its population will be centered around that age.

The U.S. Census Bureau conducts a census every 5 years, in years ending in "2" and "7." This census, authorized by Title 13 in the U.S. Code, requires participation of all state and local governments in the United States. The first national census occurred in 1957.

The geographic term “ecumene” is used to describe land that is permanently populated by human society. It can also refer to industrial and agricultural land that is permanently used to sustain the human population.

More than three-quarters of the world’s population lives in the developing world. The term “developing world” is generally used to refer to countries that do not have highly modernized and industrial economies.

The vast majority of population growth is taking place in the developing world. In recent years, more than ninety percent of population growth can be accounted for by countries in the developing world. These countries continue to grow to represent a larger and larger share of the world’s population.

Apart from Sub-Saharan Africa, all of the listed regions are considered to be some of the most densely populated on Earth. The Indian subcontinent (which generally includes Bangladesh), East Asia (which includes Eastern China and Japan), Western Europe (which includes the Netherlands and the United Kingdom), and the East Coast of the United States (which includes New York City, Philadelphia, Miami, and Washington D.C.) are the four regions of the world that are the most densely populated. South-Eastern Brazil and South-East Asia could also be added to this list.

More than half of the world’s seven billion people live in Asia. The next highest continent is Africa, with a little over a billion people. Approximately seven hundred million people live in Europe; four hundred million in South America; five hundred million in North America.

Crude birth rate (CBR) is the number of live births per year for every 1,000 people alive. When the crude death rate (CDR) is subtracted from the crude birth rate (CBR), you can determine an area's rate of natural increase. A higher CBR indicates population growth in an area, while a higher CDR indicates population decline.

IMR is the number of infant deaths (children under 1 years old) per 1,000 live births, not children under 5 years old. According to the UN, the under-5 mortality rate of the world is around 73. All of the other answer choices are true.

The population density of the United States is closest to 35 persons per square kilometer. To arrive at this answer choice, divide the population of the US (320 million people) by the geographic land area of the US (9 million kilometers).

320 million people /9 million square km = 35.56 or approximately 35 persons per square km.

The dependency ratio of a country reflects the number of people in a country whose labor supports the rest of the country that is incapable of working. It is usually determined by adding the number of retired people and children on one side, and the number of working adults on the other. In a country where the population is aging, like Italy and much of Northern Europe, the dependency ratio is growing as fewer and fewer people are supporting more and more retirees. Some geographers would argue that this is “unsustainable,” but there is as of yet insufficient evidence to conclusively say this is true.

Generation X is the name collectively given to people born after the Baby Boom generation between the late 1960s and the early 1980s. Birth rates were lower for Generation X than for the Baby Boom generation, which means the United States will soon have to deal with the consequences of a slightly aging population where fewer people are working to support more retirees.

You can use an age distribution to approximate survival rates by calculating the difference proportion of individuals in age classes.

In a triangular population pyramid, the youngest people in a society make up the highest percentage of that society. It is symptomatic of high birth rates and high death rates, so the best answer choice here is Liberia. South Africa is somewhat more developed than Liberia, so it has a population pyramid closer to a rectangle. The same is true for Moldova and to a greater extent Andorra and the United Kingdom.

Infant mortality rate measures how many babies, per thousand births, die before their first birthday. In many parts of Sub-Saharan Africa, the number is as high as one hundred. In almost all of the developed world, this number is less than ten. In what may seem like an illogical paradox, a high infant mortality rate generally correlates to a high rate of population growth—this is in part because when a culture believes many of its children will die before reaching adulthood (or even childhood), people of that culture tend to have more babies.

Since the population is expected to double over the period of those 35 years, it is most appropriate described as "doubling time." Since we know nothing of the death rate, crude or otherwise, we cannot determine the natural increase rate or even speak of life expectancy. Similarly, as we know nothing of the demographics, we cannot determine the demographic transition rate.

Almost all of Western Europe (including France) has a very high population density because a very large number of people live in a relatively small space. The same is true of Japan (which has one of the highest population densities on Earth). Although China and India are both very large countries by land size they are also the two most heavily populated nations on Earth and so are still relatively densely populated. Of these choices only Canada is both extremely large in land-size and relatively unpopulated. Approximately thirty million people live in Canada and it is either the largest or second largest country on Earth (depending on how you measure the polar region). It is one of the least densely populated countries in the world.
