But I think you are interpreting this wrong. This doesn't say that 80% of soybeans are pressed into oil at all. It says that 80% are processed into soybean meal (which gets fed to animals) and oil (which are mostly for human consumption). And with the data from ourworldindata it means that around 80%-13.2%=66.8% (very roughly) of soybeans are processed into soybean meals which is also very similar to the data ourworldindata provides:
The majority (77%) of the world’s soy is fed to livestock for meat and dairy production. 7% is fed directly to animals as soybeans, but the remainder is first processed into soybean ‘cake’.{ref}Soybean cake (sometimes referred to as soybean meal) is a high-protein feed made from the pressurisation, heat-treatment and extraction processing of soybeans. The oil is extracted from the soybeans to leave a protein-rich product.
oh I see where you made a mistake. you didn't account for the 4% at the bottom of the chart. and you don't seem to understand that soy meal is the by-product of pressing soybeans for oil. That's soybean is only about 20% oil. In order for 17% of all end uses of soybeans to be oil about 85% of all soybeans must be pressed for oil The byproduct of that process produces soy meal that soy meal makes up about 69% of the weight of the entire soybean crop. that by-product is what is fed to animals.
How do you come to this conclusion? The data on ourworldindata is showing "the allocation of global soy production to its end uses by weight". Which means the "Oil (13.2%)" is the percentage of the total weight of the global soy production that is processed into oil.
you didn’t account for the 4% at the bottom of the chart.
