Final answer:
The question discusses countries with anti-natalist and pro-natalist policies designed to manage population growth. While many countries have such policies, the United States is an example of a nation without direct governance on fertility rates, relying more on societal changes and personal choice.
Step-by-step explanation:
The question relates to population policies, specifically anti-natalist and pro-natalist policies, which have been implemented by various countries during the 20th and 21st centuries. Anti-natalist policies, like China's one-child policy, aim to reduce population growth, while pro-natalist policies, which have been seen in countries like Japan and Russia, encourage higher birth rates to increase the population.
Identifying a country that has not implemented such policies directly can be challenging, but in general, countries that have not advanced in terms of economic development or which prioritize personal liberty and religious freedom over population control might not establish strict natalist policies. Instead, these nations may experience natural changes in population growth rates due to increases in female education, economic opportunities, and access to family planning resources.
One example of a country without explicit pro-natalist or anti-natalist policies could be the United States, where growth rates reflect more about immigration patterns and personal choices rather than direct government intervention in birth policies.
