Final answer:
The question asks about the proportion of violent crimes each year in the United States attributed to juvenile arrests, but the given reference data does not provide an exact figure for this. Government sources or official crime reports would likely provide this information.
Step-by-step explanation:
The question asks for the percentage of total violent crime in the United States each year that juvenile arrests account for. Unfortunately, the provided reference information does not contain a specific answer to this query. It's important when studying societal data like juvenile crime rates and violent crimes to rely on accurate and current statistics, often provided by government reports or reputable research studies. A resource like the U.S. Department of Justice or the FBI's Uniform Crime Report could potentially offer these precise percentages.
The reference information does detail that there's been a rise in U.S. incarceration rates, with a correlation between education levels and crime rates in certain communities. But, these facts don't supply a percentage of violent crimes committed by juveniles on a yearly basis.
