A while back, on my old forum thread comparing music show wins for top girl groups, dizzcity posted the following: I wonder if there could be some sort of "inflationadjusted" chart to take into account how the number of music shows (and thus the rate of music show wins) have been increasing over the years?
That gave me the idea to examine the number of music show wins awarded per year, and create the aforementioned "inflationadjusted" graph of girl group wins.
The first thing I did was to simply go through my win database and determine how many wins were given for each year. The results are shown below:
As we can see, the number of music show wins increased dramatically in the 1990s, peaking around the same time as the top First Generation groups before declining noticeably in the early 2000s "soloist era".
However, the annual win count started rising again around 2007 and has steadily increased before leveling off in recent years.
In my initial post linked above, I was only concerned with Second Generation and later girl groups, so for the purposes of this analysis, I'll only be looking at years 2007 and beyond.
In the table below, I show the both the raw number of music show wins awarded per year, along with an inflation scaling factor. This factor is determined by dividing the number of wins per year by the number of wins awarded in the base year of 2007.
Year 
Wins Awarded 
Inflation Scaling Factor 

2007  136  ÷ 136 =  1.00 
2008  131  ÷ 136 =  0.96 
2009  143  ÷ 136 =  1.05 
2010  148  ÷ 136 =  1.09 
2011  156  ÷ 136 =  1.15 
2012  177  ÷ 136 =  1.30 
2013  227  ÷ 136 =  1.67 
2014  228  ÷ 136 =  1.68 
2015  270  ÷ 136 =  1.99 
2016  227  ÷ 136 =  1.67 
2017  245  ÷ 136 =  1.80 
2018  264  ÷ 136 =  1.94 
2019  272  ÷ 136 =  2.00 
2020  267  ÷ 136 =  1.96 
For example, in 2019 we had a total of 272 wins awarded, compared to exactly half that number (136) in 2007. Thus, 272 ÷ 136 = 2.00, which means that a win in 2019 will be divided by 2 to account for inflation. In effect, a win in 2019 is only worth the equivalent of half a win from 2007. Or, since there were double the amount of wins awarded in 2019 compared to 2007, an artist would have to will twice as much in order to capture the same percentage of wins. Hopefully this makes sense to everyone.
