"Figure 1: Decrease seen in the estimated number of child attendances at EDs and MIUs in England and Wales for violence-related injury","" "England and Wales, year ending 2009 to year ending 2018","" "","" "Notes","1. Numbers based on a sample of emergency departments, minor injury units and walk-in centres. 2. Data retrieved for October to December 2017 from Type 1 emergency departments in England recorded using the newly mandated Emergency Care Data Set (ECDS) were not used in violence attendance calculations. The number of assaults for the first nine months in 2017 was multiplied by a factor of 4/3 in order to estimate a figure for the entire year. This approach is equivalent to a fixed-value, missing-data imputation method, where the data from October to December 2017 were treated as ""missing"" and were replaced by the mean value for January to September 2017. 3. The estimated number of attendances was calculated using a national coverage ratio. See Sivarajasingam et al.'s (2015) ‘[Trends in violence in England and Wales 2010-2014’](https://www.researchgate.net/publication/288831055_Trends_in_violence_in_England_and_Wales_2010-2014) for more information about the methods. 4. Child attendances may not represent the number of children, as a child may have more than one attendance within the period.
