EVERY day, we meet people working in different lines of business and in different kinds of occupations.
We meet bus drivers on our way to school; cashiers in the fast food restaurants when we take breakfast or lunch, and teachers at school.
All of them are counted in the employed population (or working population), which consist of persons aged 15 or above who are at work during a specified period of time.
The employed population and the unemployed population (which consist of persons aged 15 or above who have no jobs and are looking for jobs) together form the economically active population , or the ''labour force''.
The employed population can be distinguished into four types of ''activity status'': self-employed, employer, employee and unpaid family worker.
A person who works on his own account, neither employed by someone else nor employing others, is regarded as self-employed. Examples are freelance designers and hawkers who work on their own.
