Industry (economics) in the context of "Social system"

A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which share industries, commercial areas, transport network, infrastructure and housing. A metropolitan area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts and even states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.

In the United States, metropolitan areas are delineated around the core of a core based statistical area, which is defined as an urban area and includes central and outlying counties. In other countries metropolitan areas are sometimes anchored by one central city such as the Paris metropolitan area (Paris). In other cases, metropolitan areas contain multiple centers of equal or close to equal importance, especially in the United States; for example, the Dallas–Fort Worth metropolitan area has eight principal cities. The Islamabad–Rawalpindi metropolitan area in Pakistan, the Rhine-Ruhr in Germany, and the Randstad in The Netherlands are other examples.

State ownership, also called public ownership or government ownership, is the ownership of an industry, asset, property, or enterprise by the national government of a country or state, or a public body representing a community, as opposed to an individual or private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from public goods and government services financed out of a government's general budget. Public ownership can take place at the national, regional, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, collective/cooperative, and common ownership.

In market-based economies, state-owned assets are often managed and operated as joint-stock corporations with a government owning all or a controlling stake of the company's shares. This form is often referred to as a state-owned enterprise. A state-owned enterprise might variously operate as a Nonprofit corporation, as it may not be required to generate a profit; as a commercial enterprise in competitive sectors; or as a natural monopoly. Governments may also use the profitable entities they own to support the general budget. The creation of a state-owned enterprise from other forms of public property is called corporatization.

Work or labour (labor in American English) is the intentional activity people perform to support the needs and desires of themselves, other people, and/or organizations. In the context of economics, work can be seen as the human activity that contributes (along with other factors of production) towards the goods and services within an economy.

Work has existed in all human societies, either as paid or unpaid work, from gathering natural resources by hand in hunter-gatherer groups to operating complex technologies that substitute for physical or even mental effort within an agricultural, industrial, or post-industrial society. One's regular participation or role in work is an occupation, or job. All but the simplest tasks in any work require specific skills, tools, and other resources, such as material for manufacturing goods. Humanity has developed a variety of institutions for group coordination of work, such as government programs, nonprofit organizations, cooperatives, and corporations.

In economics, the primary sector is the economic sector which comprises industry involved in the extraction and production of raw materials, such as farming, logging, fishing, forestry and mining. The primary sector tends to make up a larger portion of the economy in developing countries than it does in developed countries. For example, in 2018, agriculture, forestry, and fishing comprised more than 15% of GDP in sub-Saharan Africa but less than 1% of GDP in North America.

In developed countries the primary sector has become more technologically advanced, enabling for example the mechanization of farming, as compared with lower-tech methods in poorer countries. More developed economies may invest additional capital in primary means of production: for example, in the United States Corn Belt, combine harvesters pick the corn, and sprayers spray large amounts of insecticides, herbicides and fungicides, producing a higher yield than is possible using less capital-intensive techniques. These technological advances and investment allow the primary sector to employ a smaller workforce, so developed countries tend to have a smaller percentage of their workforce involved in primary activities, instead having a higher percentage involved in the secondary and tertiary sectors.

A trade association, also known as an industry trade group, business association, sector association or industry body, is an organization founded and funded by businesses that operate in a specific industry. Through collaboration between companies within a sector, a trade association coordinates public relations activities such as advertising, education, publishing and, especially, lobbying and political action. Associations may offer other services, such as producing conferences, setting industry standards, holding networking or charitable events, or offering classes or educational materials. Many associations are non-profit organizations governed by bylaws and directed by officers who are also members.

Trade associations and other industry groups are politically influential in the United States, United Kingdom, and other countries, lobbying elected officials, regulators, and other policymakers. They also invest heavily in publishing, advertising, and other forms of issue advocacy.

Waste management industry, or waste industry for short, subsumes all industrial branches concerned with waste management, waste dumping, waste recycling and - to a lesser degree - waste prevention.

Within Germany, waste management has evolved into a large economic sector. There are more than 270,000 people working in some 11,000 companies with an annual turnover of around 70 billion euros (~$78 billion). More than 15,500 waste management facilities help to conserve resources through recycling and other recovery operations. On a global scale, the market size is expected to reach $530.0 billion by 2025 from $330.6 billion in 2017, with a compound annual growth rate of 6.0%. The growth might even continue when, according to a World Bank report, global waste production will grow by 70% from 2018 to 2050, unless severe measures are taken.
