Eugenics is the “science” of improving the human population by encouraging only a specific group of people to breed. It generally favors the growth of one race over others within a society. Eugenics was popular in Europe in the early twentieth century, but continues to be influential in some parts of the world to this day.

China’s population grew immensely in the twentieth century from an already high starting point. In the 1970s, Chinese politicians began to worry that the population was growing too fast, and that soon China’s population growth would be out of control and the country would not be able to cope with the demand for resources. The government implemented a “one child” policy that provides incentives for parents who have only one child and punishments for those that have more. This is not uniformly enforced and has led to many social ills, but it has also curtailed China’s massive population growth.

“Neo-Malthusians” generally adhere to Thomas Malthus’ Principle of Population, but have adapted it to suit the modern time period. “Neo-Malthusians” believe that the population of the world is growing too quickly for the scale of agricultural production to keep up. “Neo-Malthusians” advocate for programs and policies designed to control population growth, so they would be most likely to support a program that limits family size to two children.

An “expansive population policy” is an official government policy designed to encourage the population to conceive and raise multiple children. Unlike a “restrictive population policy,” its primary goal is to increase the rate of population growth to prevent the economic and social welfare problems that arise with an aging population. “Expansive population policies” are most common in Western and Northern Europe where birth rates are some of the lowest in the world. Countries like Sweden, France, the U.K., Germany, and Italy have some form of “expansive population policies” in place.

Most studies and statistics on the subject demonstrate that any country that prioritizes education and providing universal access to education is likely to see a decline in the rate of its population growth. This is because as people become better educated they have more opportunities open to them and more control over their lives - this is particularly significant for women. Women who are well-educated are less likely to have unplanned pregnancies, less likely to have large families, and more likely to start those families at a later age. All of this contributes to a decline in the rate of population growth, or, in geographic parlance, a decline in the “natural increase rate.”

A census is an official government survey of the population of a government’s country. It usually includes questions about race, gender, religious identity, income, and a great many other things. In the United States, it is conducted every ten years and is used to determine representation in Congress (among other things).

China's one-child policy has historically featured all of the following: awareness campaigns, inspections, fines, and forced abortions.

Eugenic policies favor one racial group and may lead to the subjugation of other groups with less political or social capital. One example is the Nazi Germany policy favoring people of Aryan descent over other ethnic and cultural groups.

Eugenics involve the set of beliefs and practices that aim to improve the genetic quality of the human race. During the Progressive Era eugenics was accepted as a method of preserving and improving the dominant population groups. Today, eugenics is associated with racist and nativist elements.

Countries that discourage or ban the use of contraceptives are more likely to experience all of the provided answer options. High death rates result from the rampant spread of sexual disease, particularly AIDS. High birth rates result from the inability of women to control the reproductive process, which is of course linked to gender inequality. Many sociologists and historians agree that the relatively rapid increase in gender equality in many parts of the world in the last fifty years has been primarily caused by the availability of contraception, which allows women to dictate when, and with whom, they have children.
