Ages when British Isles titles obtained
Posted: Thu Jun 02, 2011 1:02 am
This post follows on from the data presented several months ago here:
http://www.ecforum.org.uk/viewtopic.php?f=27&t=2165
That is a thread from September 2010, titled: Timeline of British Isles titles (1950-2010). That list only goes up to 2010, and does not include recent title applications (though it does include one from early 2011).
I've stripped out the titles awarded in the 1950s, the ones gained under a federation other than ENG, SCO, WLS, or IRL, and stripped out a couple of the post-1950s title awards (specifically the GM titles for Golombek and Penrose), as those are outliers, awarded (I think) following their playing careers.
That left 47 GM titles, 122 IM titles, 6 WGM titles, and 9 WIM titles. I then dropped the WGM and WIM data, because there wasn't enough to give a meaningful distribution (possibly I should have also restricted this to one federation such as ENG, but including SCO, WLS and IRL increased the data).
I then ordered each subset by the age when the title was awarded. Unfortunately, the data is only an age range obtained by subtracting the birth year from the title year, as I've been unable to pinpoint the exact ages, but for various reasons this shouldn't make too much difference.
The results are below.

By decade, that is : teens (6); 20s (33); 30s (7); 40s (1).
Mode is 27-28, with 28-29 next (i.e. most common age in the British Isles to attain the GM title is 27-29).
This analysis has been done back in 2009 for some set of GMs worldwide, see here:
http://www.ecforum.org.uk/viewtopic.php ... 314#p38314
"...a figure of 1238 is broken down into 233 obtaining the GM title in their teens, 606 in their 20s, 293 in their 30s, 62 in their 40s, and 44 after the age of 50..."
So it looks like the British GMs' age-obtained distribution is pretty much in line with the overall distribution.

By decade, that is : teens (35); 20s (65); 30s (17); 40s (4); 50s (1).
Mode is 19-20 (with 23-24 next). Sustained peak from 18-25 as most likely age in the British Isles for attaining the IM title.
I don't think anyone has done an analysis of any worldwide dataset for the ages at which the IM title has been obtained (like the one quoted above for the GMs), though it should be fairly easy to do. I would think the distribution would be fairly similar to that seen here.
If anyone wants to plot the above in graphical form, please feel free.
Quiz questions (to make this more interesting):
1) Who are the three youngest GMs listed above? All 18 or under.
2) Who are the five youngest IMs listed above? All 16 or under.
3) Who are the eight oldest GMs listed above? All 30 or over.
4) Who are the five oldest IMs listed above? All 40 or over.
EDIT: Until proper graphics can be done, added ASCII-style bar charts.
