I did a graph of Harry’s engagements for mental health since the launch of Heads Together after receiving a message asking if his work in the area had tailed off. @avidroyalfan– one of the few people in the fandom who loves graphs and data as much as me- asked if I could do one including Kate and William so voila. I’ve gone hella gender normative so Kate’s pink, William’s blue and Harry’s black because it looked better next to the other colours. This graph shows the number of mental health focused engagements completed each month since the launch in May 2016:
NB. Some things to consider: Their spike in engagements in March/April 2017 came about due to the London Marathon. Kate was off work with Hyperesmesis Gravidarum in September 2017 and on maternity leave from late March until early October 2018. Harry married in May 2018 and had a reduced programme that month.
