Weighted distribution
The share of the category's total sales made by the stores that sell your product. It weights each store by how much of the category it sells (NielsenIQ).
Why it matters
It measures the quality of your distribution. 40% numeric distribution can mean 70% weighted distribution if you are in the biggest stores.
How to calculate
Category sales of the stores selling your product ÷ total category sales in the market × 100.
