Final answer:
False, the decline in criminal violence in the United States since the 1990s does include a reduction in family violence, contrary to the suggestion that family violence has slightly increased.
Step-by-step explanation:
The statement that the general decline in criminal violence in the United States since the 1990s does not include family violence, which seems to have slightly increased, is false. According to crime trends in the United States, overall crime rates, particularly for violent and gun-related crimes, have been on the decline since peaking in the early 1990s. However, public perception has not always aligned with these statistics, as many believe that crime is worse now than it was previously.
When it comes to crime trends, option a, which states that rates of violent and nonviolent crimes are decreasing, describes the situation accurately. It has been observed that while general crime rates have seen a decrease, this has not been evenly spread across all types of crimes, nor does it correlate perfectly with states' rates of incarceration. With regards to family violence specifically, the question has been structured based on a presumption which, based on general trends, does not hold true as evidence suggests an overall decline in violent crimes, including domestic or family violence. Nonetheless, accurate and up-to-date data specifically isolating family violence would be required to confirm this point.
