This sounds very conspiracy-y. I'm sure there are metrics like consumption of certain items like food, medicine, etc. which is at a mostly consistent level accross subsections the human population. Like arthiris medication, foodstuffs, diapers etc.
It would take a very involved conspiracy to make these numbers fall in line with where they should be given a certain pop cap, and I'm not sure what would be the benefit.
Like all conspiracy theories, if it requires a coordination of large unrelated organizations over long timeframes, which seems impossible even over the table, its almost certainly fake.
Like you can fake census data, but not how many cans of beans does a US-headquartered supermarket chain sells.
