It is distinct from the century known as the 1900s which began on January 1, 1900 and ended on December 31, 1999.

The 20th century was dominated by a chain of events that heralded significant changes in world history as to redefine the era: World War I and World War II, nuclear power and space exploration, nationalism and decolonization, the Cold War and post-Cold War conflicts; intergovernmental organizations and cultural homogenization through developments in emerging transportation and communications technology; poverty reduction and world population growth, awareness of environmental degradation, ecological extinction; and the birth of the Digital Revolution.

Information and communication technology is another/extensional term for information technology which stresses the role of unified communications and the integration of telecommunications, computers as well as necessary enterprise software, middleware, storage, and audio-visual systems, which enable users to access, store, transmit, and manipulate information.

Cultural homogenisation is an aspect of cultural globalisation, listed as one of its main characteristics, and refers to the reduction in cultural diversity through the popularization and diffusion of a wide array of cultural symbols—not only physical objects but customs, ideas and values.

The Digital Revolution is the shift from mechanical and analogue electronic technology to digital electronics which began anywhere from the late 1950s to the late 1970s with the adoption and proliferation of digital computers and digital record keeping that continues to the present day.

It saw great advances in communication and medical technology that by the late 1980s allowed for near-instantaneous worldwide computer communication and genetic modification of life.

Life is a characteristic that distinguishes physical entities that do have biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased, or because they never had such functions and are classified as inanimate.

Health technology is defined by the World Health Organization as the application of organized knowledge and skills in the form of devices, medicines, vaccines, procedures and systems developed to solve a health problem and improve quality of lives.

Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology.

Global total fertility rates, sea level rise and ecological collapses increased; the resulting competition for land and dwindling resources accelerated deforestation, water depletion, and the mass extinction of many of the world's species and decline in the population of others; consequences which are now being dealt with.

The total fertility rate, sometimes also called the fertility rate, absolute/potential natality, period total fertility rate, or total period fertility rate of a population is the average number of children that would be born to a woman over her lifetime if:

Ecological collapse refers to a situation where an ecosystem suffers a drastic, possibly permanent, reduction in carrying capacity for all organisms, often resulting in mass extinction.

Deforestation, clearance or clearing is the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use.

It took all of human history up to 1804 for the world's population to reach 1 billion; world population reached an estimated 2 billion in 1927; by late 1999, the global population reached 6 billion.

The history of the world is the history of humanity, as determined from archaeology, anthropology, genetics, linguistics, and other disciplines; and, for periods since the invention of writing, from recorded history and from secondary sources and studies.

Global literacy averaged 80%; global lifespan-averages exceeded 40+ years for the first time in history, with over half achieving 70+ years.

Literacy is traditionally understood as the ability to read, write, and use arithmetic.
