### D**efinition**

For a product, weighted distribution compares the sales value of pharmacies selling to the sales value of the pharmacy total.

**Calculation**

weighted distribution = sales value of pharmacies selling / sales value of total dispensing value

The interpretation of a distribution of less than 5% is to be taken with caution.

**Tutorial**

For a product A, a 50% sales value distribution means that the pharmacies selling represent 50% of the sales value of the total officinal total.

**Terminology**

The selling value distribution can be written as DVV. It is translated into English by Weighted distribution or WD.

**Geographical sectorisation / Customer type**

In this case, the referent of your total value of pharmacies sold is that of the geographical sectorisation or customer type studied.

For example, your product is sold in 600 pharmacies in a geographical sector that generate a turnover of €100,000,000 over your study period.

In the same sector, 1,000 pharmacies sold a medicinal product over the same period for a total turnover of €150,000,000.

Your DVV will then be 67% (€100,000,000 out of €150,000,000).
