Answer:
Countries considered to be in the first world are typically characterized by high levels of prosperity, democracy, and political and economic stability. First world countries are distinguished by a number of other factors as well, including a high literacy rate, free enterprise, and the rule of law.
Step-by-step explanation:
The term “first world” originally applied to countries that were aligned with the United States and other Western nations in opposition to the former Soviet Union.
Many first world countries have large populations that live in abject poverty, which is more typical of developing countries; however, some countries that are classified as third world are quite prosperous.
The United States, Canada, Australia, New Zealand, and Japan are all examples of countries that are considered to be first world countries. There are also several countries in Western Europe that are eligible, particularly the United Kingdom, France, Germany, Switzerland, and the Scandinavian countries.
There are many different ways in which first world countries can be defined. For instance, a nation may be considered to be of the first world if it is aligned or friendly with Western nations or nations located in the Northern Hemisphere, if it is highly industrialized, if it has a low poverty rate, and/or if its citizens have easy access to modern resources and infrastructure.
Gross domestic product (GDP), gross national product (GNP), mortality rates, and literacy rates are some of the metrics that have been used to define first world nations. Other metrics that have been used include per capita gross domestic product (GDP) and per capita gross national product (GNP). The Human Development Index (HDI) is another indicator that can be used to determine which countries have the potential to be classified as first world countries.
