In the article, it also references that the 20.7% rate of lifetime violence is 9 times higher versus a population without serious mental illness (~ 2.3%) (Reference link).

I reckon the difference between this and CDC's figures will be in the methodology. CDC using a US Population and telephone/mobile phone survey, and Khalifeh et al using a systematic review of english published journal articles.

Based on this and without completing critiquing the sources of data for the systematic review, it could be that the US has a higher rate of violence vs other parts of the world? Or the data methodologies differ that has led to this difference?
