Explanation:

In the production and economic distribution activity, three types of agents intervene: families, companies and the State.

Families have a double role in the market economy: they are both the elementary consumption units and the owners of productive resources. The word 'family' must be understood in a broad sense, not just the nuclear family of the Judeo-Christian tradition. Families that are formed by a single couple or a single individual are more frequent in our societies. In underdeveloped countries and in rural areas of developing countries, self-consumption is very common, that is, families produce what they will consume, food, household items, even clothing; since the products destined for self-consumption are not counted in the statistics, international comparisons are sometimes very misleading. Cleaning and preparation of food provided at home by family members should also be considered self-consumption. In general it is considered, although perhaps it should not be so, that in the developed western countries the production destined to self-consumption is very small in comparison with the total of the country, negligible for statistical purposes and negligible for scientific purposes. In summary: families do not produce, they only consume.
