Correct Answer: C) the number of people who are out of work and actively looking for work

Explanation

This Economics question is asking about what the unemployment rate measures as a percentage of the labour force. The options are: A) the number of people in an economy who do not have jobs, B) the number of people in an economy who have jobs, C) the number of people who are out of work and actively looking for work (which is the correct answer), and D) the number of people who are looking for work.

The unemployment rate is a measure of the percentage of the labour force that is unemployed. The labour force includes people who are employed and those who are actively seeking work. Therefore, options A and B are incorrect as they do not take into account the labour force as a whole.

Option C is the correct answer because it refers to the number of people who are out of work and actively looking for work, which is a subset of the labour force. These are people who are willing and able to work, but are currently unable to find employment. By measuring this as a percentage of the labour force, we can get an idea of the level of unemployment in an economy.

Option D is not the correct answer as it is too broad. It includes people who are not actively seeking work, which is not relevant to the unemployment rate.

In summary, the unemployment rate measures the number of people who are out of work and actively looking for work as a percentage of the labour force. This is useful for understanding the level of unemployment in an economy.
