Fund ownership counts N-PORT filers only, so it is a floor rather than a census — pensions, insurers and direct holders are not visible here, and the remainder is not “held by individuals”.

Fund ownership is a subset of institutional 13F ownership — the two describe overlapping populations and must not be added together.
