"NCVS is the Nation's primary source of information on criminal victimization. Each year, data are obtained from a nationally representative sample of about 40,000 households comprising nearly 75,000 persons on the frequency, characteristics and consequences of criminal victimization in the United States. Each household is interviewed twice during the year. The survey enables BJS to estimate the likelihood of victimization by rape, sexual assault, robbery, assault, theft, household burglary, and motor vehicle theft for the population as a whole as well as for segments of the population such as women, the elderly, members of various racial groups, city dwellers, or other groups. The NCVS provides the largest national forum for victims to describe the impact of crime and characteristics of violent offenders."

The NCVS doesn't rely on police reports, or reporting to any law enforcement agency. It surveys the general public directly about their experience of crime victimization. A sample of 40,000 households are surveyed repeatedly over a three year period, this includes about 70,000 individuals 12 or older.

Links to the questionnaires and the methodology are included in the one above.

The OP's link does have a disclaimer that the methodology is questioned, but I think the proportion is in the ballpark of what's given in the OP's graphic.
