Which of the following stands true in regard to "Worker-population" ratio?

1. It is an indicator used for analysing the employment situation in the country.
2. Ratio is inversely proportional to engagement of workforce in economic activities.
3. It is useful in knowing the proportion of population that is actively contributing to production of goods and services.

1 and 3

If the Worker-population ratio is higher, it means that the engagement of people is greater; if the ratio for a country is medium, or low, it means that a very high proportion of its population is not involved directly in economic activities. That means ratio is directly proportional to engagement of workforce in economic activities.
