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.

On 14 April 2013 the former municipalities of Besazio , Ligornetto and Meride merged into the municipality of Mendrisio . Meride is first mentioned in 852 as Melede . In 1430 it was mentioned as Merede . The area around Meride is of great interest to geologists and paleontologists , due to

In 1483, Meride separated from the mother church at Riva San Vitale, and became an independent parish.

Switzerland has a relatively high number of small municipalities, with a population of 1,000 or less, especially in rural areas. Because of the increasing difficulty in providing professional government services and in finding volunteers for political offices in small municipalities, the cantons tend to encourage voluntary mergers of municipalities.

Some of the reasons for the "Modern Rise of Population" were particularly investigated by the British health scientist Thomas McKeown (1912–1988). In his publications, McKeown challenged four theories about the population growth: Although the McKeown thesis has been heavily disputed, recent studies have confirmed
1550-519: The industrial revolution . The most significant increase in the world's population has been since the 1950s, mainly due to medical advancements and increases in agricultural productivity . Due to its dramatic impact on the human ability to grow food, the Haber process , named after one of its inventors, the German chemist Fritz Haber , served as the "detonator of the population explosion ", enabling

The Bürgergemeinde also often holds and administers the common property in the village for the members of the community. Each canton determines the powers and responsibilities of its municipalities. These may include providing local government services such as education, medical and social services, public transportation, and tax collection. The degree of centralization varies from one canton to another. The federal constitution protects

In the city of Zürich it was not until the Municipal Act of 1866 that the political municipality came back into existence. The relationship between the political municipality and the Bürgergemeinde was often dominated by the latter's ownership of community property. Often

A mix of technological advancement that improved agricultural productivity and sanitation and medical advancement that reduced mortality increased population growth. In some geographies, this has slowed through the process called the demographic transition , where many nations with high standards of living have seen a significant slowing of population growth. This

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 2022 projections from the United Nations Population Division (chart #1) show that annual world population growth peaked at 2.3% per year in 1963, has since dropped to 0.9% in 2023, equivalent to about 74 million people each year, and could drop even further to minus 0.1% by 2100. Based on this,

The creation of a uniform Swiss citizenship, which applied equally for citizens of the old towns and their tenants and servants, led to conflict.

For example, the population of Chad has ultimately grown from 6,279,921 in 1993 to 10,329,208 in 2009, further straining its resources. Vietnam , Mexico , Nigeria , Egypt , Ethiopia , and
