Published estimates for the 1st century ("AD 1") suggest uncertainty of the order of 50% (estimates range between 150 and 330 million). Some estimates extend their timeline into deep prehistory, to " 10,000 BC", i.e., the early Holocene, when world population estimates range roughly between 1 and 10 million (with an uncertainty of up to an ...
High, medium, and low projections of the future human world population [1] In world demographics, the world population is the total number of humans currently alive. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took around 300,000 years of human prehistory and history for the human population to ...
Demographics of the world. Earth has a human population of over 8 billion as of 2024, with an overall population density of 50 people per km 2 (130 per sq. mile). Nearly 60% of the world's population lives in Asia, with more than 2.8 billion in the countries of India and China combined.
In 2010, according to the Institute for Health Metrics and Evaluation, 52.8 million people died. [2] In 2016, the WHO recorded 56.7 million deaths [ 3 ] with the leading cause of death as cardiovascular disease causing more than 17 million deaths (about 31% of the total) as shown in the chart to the side.
Parfit argues that the size of the "cosmic endowment" can be calculated from the following argument: If Earth remains habitable for a billion more years and can sustainably support a population of more than a billion humans, then there is a potential for 10 16 (or 10,000,000,000,000,000) human lives of normal duration.

As of the early 21st century, 56 million people die per year. The most common reason is cardiovascular disease, which is a disease that affects the heart or blood vessels. [6] As of 2022, an estimated total of almost 110 billion humans have died, or roughly 94% of all humans to have ever lived. [7]
World population milestones went unnoticed until the 20th century, since there was no reliable data on global population dynamics. [2] The population of the world reached. [3][4] Old estimates put the global population at 9 billion by 2037–2046, 14 years after 8 billion, and 10 billion by 2054–2071, 17 years after 9 billion; however these ...
This is a list of the largest known epidemics and pandemics caused by an infectious disease in humans. Widespread non-communicable diseases such as cardiovascular disease and cancer are not included. An epidemic is the rapid spread of disease to a large number of people in a given population within a short period of time; in meningococcal ...
