Demographic features of the population of Botswana include population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects.
Sources disagree as to the current population of Eritrea, with some proposing numbers as low as 3.6 million and others as high as 6.7 million. Eritrea has never conducted an official government census.
The Iraqi people are people originating from the country of Iraq.
The total number of military and civilian casualties in World War I was about 40 million: estimates range from around 15 to 22 million deaths and about 23 million wounded military personnel, ranking it among the deadliest conflicts in human history.

West Asia, also called Western Asia or Southwest Asia, is the westernmost region of Asia. As defined by most academics, UN bodies and other institutions, the subregion consists of Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian highlands, the Levant, the island of Cyprus, the Sinai Peninsula and the South Caucasus. The region is separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. West Asia contains the majority of the similarly defined Middle East. The Middle East is a political term that has changed many times depending on political and historical context while West Asia is a geographical term with more consistency. It excludes most of Egypt and the northwestern part of Turkey, and includes the southern part of the Caucasus.
Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 8.1 billion in 2024. The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100. However, some academics outside the UN have increasingly developed human population models that account for additional downward pressures on population growth; in such a scenario population would peak before 2100. Others have challenged many recent population projections as having underestimated population growth.
Medieval demography is the study of human demography in Europe and the Mediterranean during the Middle Ages. It estimates and seeks to explain the number of people who were alive during the Medieval period, population trends, life expectancy, family structure, and related issues. Demography is considered a crucial element of historical change throughout the Middle Ages.
This article lists current estimates of the world population in history. In summary, estimates for the progression of world population since the Late Middle Ages are in the following ranges:
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 reach a billion and only 218 years more to reach 8 billion.
Earth has a human population of over 8 billion as of 2024, with an overall population density of 50 people per km2. Nearly 60% of the world's population lives in Asia, with more than 2.8 billion in the countries of India and China combined. The percentage shares of China, India and rest of South Asia of the world population have remained at similar levels for the last few thousand years of recorded history. The world's literacy rate has increased dramatically in the last 40 years, from 66.7% in 1979 to 86.3% today. Lower literacy levels are mostly attributable to poverty. Lower literacy rates are found mostly in South Asia and Sub-Saharan Africa.
Human population projections are attempts to extrapolate how human populations will change in the future. These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. Models of population growth take trends in human development and apply projections into the future. These models use trend-based-assumptions about how populations will respond to economic, social and technological forces to understand how they will affect fertility and mortality, and thus population growth.
The 0s began on January 1, AD 1 and ended on December 31, AD 9, covering the first nine years of the Common Era. It is one of two "0-to-9" decade-like timespans that contain nine years, along with the 0s BC.
The Viking Age in Estonia was a period in the history of Estonia, part of the Viking Age. It was not a unified country at the time, and the area of Ancient Estonia was divided among loosely allied regions. It was preceded by the Bronze and Early Iron Ages in Estonia, during which an agrarian society had developed, the Migration Period, and Pre-Viking Age with the Viking Age itself lasting between 800 and 1050 AD. It is often considered to be part of the Iron Age period which started around 400 AD and ended around 1200 AD. Some 16th-century Swedish chronicles attribute the Pillage of Sigtuna in 1187 to Estonian raiders.
