Insufficient evidence of impact

Estimated impact on violent crime

The average impact that an approach is likely to have on violent crime.

HARMFUL -: The approach is likely to increase violent crime.
LOW -: The approach is likely to result in small reductions in violent crime. It is in the bottom third of approaches according to impact.
MODERATE -: The approach is likely to result in moderate reduction in violent crime. It is in the middle third of approaches according to impact.
HIGH -: The approach is likely to result in large reductions in violent crime. It is in the top third of approaches according to impact.
? -: There is not enough evidence to provide an impact estimate

Cost

The average cost of an approach per participant.

: Not enough information
: £0-500
: £500-1,500
: £1,500+

Evidence quality

The quality of the research available to calculate the impact estimate. This rating reflects our confidence that new research will not lead to large changes in the impact estimate.

: There is not enough research to create an impact estimate.
: We have very low confidence in this impact estimate
: We have low confidence in this impact estimate
: We have moderate confidence in this impact estimate
: We have high confidence in this impact estimate
: We have very high confidence in this impact estimate
