Africa

Africa is the world's second-largest and second-most-populous continent. At about 30.2 million km² (11.7 million sq mi) including adjacent islands, it covers six percent of Earth's total surface area and 20.4 percent of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two de facto independent states with limited or no recognition.

Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4.Algeria is Africa's largest country by area, and Nigeria by population. Africa, particularly central Eastern Africa, is widely accepted as the place of origin of humans and the Hominidae clade (great apes), as evidenced by the discovery of the earliest hominids and their ancestors, as well as later ones that have been dated to around seven million years ago, including Sahelanthropus tchadensis, Australopithecus africanus, A. afarensis, Homo erectus, H. habilis and H. ergaster – with the earliest Homo sapiens (modern human) found in Ethiopia being dated to circa 200,000 years ago. Africa straddles the equator and encompasses numerous climate areas; it is the only continent to stretch from the northern temperate to southern temperate zones.

Gender

Gender is the range of characteristics pertaining to, and differentiating between, masculinity and femininity. Depending on the context, these characteristics may include biological sex (i.e. the state of being male, female or intersex), sex-based social structures (including gender roles and other social roles), or gender identity.

Sexologist John Money introduced the terminological distinction between biological sex and gender as a role in 1955. Before his work, it was uncommon to use the word gender to refer to anything but grammatical categories. However, Money's meaning of the word did not become widespread until the 1970s, when feminist theory embraced the concept of a distinction between biological sex and the social construct of gender. Today, the distinction is strictly followed in some contexts, especially the social sciences and documents written by the World Health Organization (WHO). However, in many other contexts, including some areas of social sciences, gender includes sex or replaces it. Although this change in the meaning of gender can be traced to the 1980s, a small acceleration of the process in the scientific literature was observed in 1993 when the USA's Food and Drug Administration (FDA) started to use gender instead of sex. In 2011, the FDA reversed its position and began using sex as the biological classification and gender as "a person's self representation as male or female, or how that person is responded to by social institutions based on the individual's gender presentation." In non-human animal research, gender is also commonly used to refer to the physiology of the animals.

Net worth

Net worth (sometimes called net or wealth) is the total assets minus total outside liabilities of an individual or a company. Net worth is used when talking about the value of a company or in personal finance for an individual's net economic position.

Put another way, net worth is any asset owned minus any debt owed. Net worth can be a negative number if one's debt owed is greater than the value of the assets owned.

Companies

Net worth in business is generally based on the value of all assets and liabilities at the carrying value which is the value as expressed on the financial statements. To the extent items on the balance sheet do not express their true (market) value, the net worth will also be inaccurate. On reading the balance sheet, if the accumulated losses exceed the shareholder's equity, it is a negative value for net worth.

For a company, this is called shareholders' preference and may be referred to as book value. Net worth is stated as at a particular year in time.

Net worth in this formulation is not an expression of the market value of the firm: the firm may be worth more (or less) if sold as a going concern.

South Africa

South Africa, officially the Republic of South Africa, is the southernmost sovereign state in Africa. It is bounded on the south by 2,798 kilometers of coastline of southern Africa stretching along the South Atlantic and Indian Oceans, on the north by the neighbouring countries of Namibia, Botswana and Zimbabwe, and on the east by Mozambique and Swaziland, and surrounding the kingdom of Lesotho. South Africa is the 25th-largest country in the world by land area, and with close to 53 million people, is the world's 24th-most populous nation. It is the southernmost country on the mainland of the Old World or the Eastern Hemisphere.

South Africa is a multiethnic society encompassing a wide variety of cultures, languages, and religions. Its pluralistic makeup is reflected in the constitution's recognition of 11 official languages, which is among the highest number of any country in the world. Two of these languages are of European origin: Afrikaans developed from Dutch and serves as the first language of most white and coloured South Africans; English reflects the legacy of British colonialism, and is commonly used in public and commercial life, though it is fourth-ranked as a spoken first language.
