Comment 13 for bug 536437

I have a suggestion that solves this problem: Add another tab to the Ware Statistics window which would show the global stock minus global demand (that is, the total storage capacity of buildings that consume the given ware, respecting storage limits set by player for each building, and of course the demand for tools and weapons generated by vacant worker and soldier slots).

The Economy Health tab is nearly useless because once you burn through the initial stock, the graph will settle near zero even though the demand for given stock is several times larger than supply.
