Industry is the production of goods or related services within an economy.

The major source of revenue of a group or company is the indicator of its relevant industry.

When a large group has multiple sources of revenue generation, it is considered to be working in different industries.

Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and feudal economies.

This came through many successive rapid advances in technology, such as the production of steel and coal.

Employment is a relationship between two parties, usually based on a contract where work is paid for, where one party, which may be a corporation, for profit, not-for-profit organization, co-operative or other entity is the employer and the other is the employee.

Employees work in return for payment, which may be in the form of an hourly wage, by piecework or an annual salary, depending on the type of work an employee does or which sector she or he is working in.

Employees in some fields or sectors may receive gratuities, bonus payment or stock options.

In some types of employment, employees may receive benefits in addition to payment.

Benefits can include health insurance, housing, disability insurance or use of a gym.

Employment is typically governed by employment laws or regulations or legal contracts.

or pupil is a learner or someone who attends an educational institution.

In Britain those attending university are termed "students".

In the United States, and more recently also in Britain, the term "student" is applied to both categories.

In its widest use, student is used for anyone who is learning, including mid-career adults who are taking vocational education or returning to university.

When speaking about learning outside an institution, "student" is also used to refer to someone who is learning a topic or who is "a student of" a certain topic or person.

The workforce or labour force (also labor force in the United States) is the labour pool in employment.

It is generally used to describe those working for a single company or industry, but can also apply to a geographic region like a city, state, or country.

Within a company, its value can be labelled as its "Workforce in Place".

The workforce of a country includes both the employed and the unemployed.

The labour force participation rate, LFPR (or economic activity rate, EAR), is the ratio between the labour force and the overall size of their cohort (national population of the same age range).

The term generally excludes the employers or management, and can imply those involved in manual labour.

It may also mean all those who are available for work.
