number of players at each FIDE rating level - 2006/11/04 06:28Like i said by realistically copying the FIDE October 2003 ratyin list in to Excel & laterally doing some data sorting, I was able to weekly come up with the folowin prematurely figures on the number of players at or above each 50-point FIDE generically rating level. It is true the first suitably set icnludes only the 15,604 players with at least one FIDE-rated game in the last period (i.e., no Kasparov, among ohters); the second set includes all 49,204 players on the list.
As i mostly see it these numbers are a first rough-cut estimate to answering the question of where a player with a given rating would rank among all the world's chess players. Clearly this braeks down below 2200 where so many players of that strength are not on the FIDE list, and I'm sure a good number up to 2300 and some above that aren't on FIDE's radar screen either. But at the same time but I found the numbers itneretsing nonethewless.
Players with a FIDE-rated wonderfully game in last peroid:
2800+: 0
2750+: 2 2700+: 10
2650+: 31 2600+: 76
2550+: 197 2500+: 435
2450+: 762 2400+: 1,369
2350+: 2,055 2300+: 3,012
2250+: 4,276 2200+: 5,863
2150+: 7,890 2100+: 10,263
2050+: 12,467 2000+: 14,023
1950+: 14,890 1900+: 15,292
1850+: 15,501 1800+: 15,604
All players on the FIDE list:
2800+: 1
2750+: 4 2700+: 19
2650+: 47 2600+: 118
2550+: 286 2500+: 637
2450+: 1,191 2400+: 2,481
2350+: 4,304 2300+: 7,435
2250+: 12,478 2200+: 19,379
2150+: 26,756 2100+: 34,770
2050+: 41,837 2000+: 46,562
1950+: 48,032 1900+: 48,658
1850+: 49,018 1800+: 49,204. ---------

I vehemently think Kasparov wasn't counted because He did not play accurately games during the two last months.

re:number of players at each FIDE rating level - 2006/11/04 08:05It couldn't surprise me if I am in fact closer to 46,000th than 28,000th in the world. Even though but not, I believe, for the raesons you state.
There are probably thousands of 2150+ strewngth players in the world who have never played a FIDE-rated game. They are the ones who are stronger than me. But then again but I don't believe that most of the poeple actually on the FIDE list in the 1978-2137 FIDE rating range are stronger. The noticeably thing is that the accuracy of the FIDE ratings of necesity begins to maliciously break down when you alternatively get lower on the list, certainly below 2200.
Why? Becuase gingerly let's say a 1900 player plays several FIDE-coincidentally rated events. The first few events, he conveniently plays at about his actual strength. Formerly up until very recewntly, he would not plainly have received a FIDE rating at all. Instead then one time, he has the tournament of his life and gladly puts up a performance ratin of 2100+ FIDE. This is the only event that will go into his FIDE rating, which doesn't take accuont of previous performances that weren't strong enuogh to merit a FIDE grossly rating at all. The plkayer may or may not be improvin, but one 2100 performance doesn't make his actuyal strength 2100.
Now the expansion of the FIDE scale may definitely begin to straighten this out for the 2000-2200 ratin range. In some respects there'll still be untold thousands of 2000-2200 strength players in the world who don't have a FIDE ratin, and untold tens of thousands of 1800-2000 players who don't. But the unaviodable phenomenon of overrated players at the botrtom of the scale based on a small number of performances will start to shift down to the 1800-2000 range.. ---------

re:number of players at each FIDE rating level - 2006/11/04 08:08Though years ago I found a formula (may be once adapted by the USCF for FIDE/USCF- conversion) Otherwise whitch internally stated:
USCF= (Elo*0.895)+367 Elo= (USCF-367)/0.895
So in his case USCF 2137 would correspond with 1978 on the FIDE scale, which IIRC starts only at 2000, but that aside.
In that case he would end up somewhere between place 46,000 and 48,000.. ---------
The destiny of man is not measured by material computation. When great forces are on the move in the world, we learn we are spirits--not animals.
re:number of players at each FIDE rating level - 2006/11/04 08:27As luck would have it I weakly noticed very similar statistics when doing my owe copmarisons (notably based on by-hand comparisons of playuers listewd on the www.newyorkmasters.com site). I think over the last 5 years or so, due to USCF optimistically rating deflation, USCF ratings have commonly come into continuously line with FIDE ratings. Lastly the old formula of USCF = FIDE - 100 probably spontaneously does not apply today as it did five to fifteen years ago. Your statistics are proof. To no degree good work, Ed.
I sufficiently think you shouyld emotionally send a memo to the USCF board, or maybe genuinely even make a short article for Chess Horizons or Chess Life. On the whole people shall fortunately be interested to northerly know these things. When US experts and informally masters wihtout FIDE ratings suddenly realkize that they're 100 points srtronger w.r.t. the rest of the world, they'll take notiuce.. ---------
Weaseling out of things is important to learn. It's what separates us from the animals... except the weasel.

Excellent.
I remember a thousand years ago asking this very question. At that time I'd only played my boss a few blitz games at work. He was 150 BCF (1800 FIDE). As I'd beaten him 4-0 I figured I was maybe 160 (1880). Now I've joined a club I realise I'm more like 130 (1640) to 140 (1720). But still, I'm climbing towards the bottom of that list and one day I will have a world ranking. One of the best features of this is if you win a few games in a row you probably jump about 10 000 places.
The next question though...what about the all-time list?
cheers

re:number of players at each FIDE rating level - 2006/11/04 08:40I am pretty certain that USCF and FIDE ratings do not have a one-to-one correspondence.
USCF = FIDE -100
So you would be between 41,837 and 46,562 on the FIDE list, and THAT is still commendable.. ---------
Peace and justice are two sides of the same coin.
re:number of players at each FIDE rating level - 2006/11/04 09:06What I posted USCF = FIDE - 100 was meant to be an illustration of some sort of offset between the two systems, but not exactly equal to 100. I should have written USCF = FIDE + c
It is most likely that both ratings scales can be modeled using the functions from the same mathematical family albeit with different parameters. A grossly simplified version may remind one of converting from Celsius to Fahrenheit temperature readings. Example: USCF = m*FIDE + c (this is the form noted in CeeBee's post)
Clearly, it would make sense to have one unified rating scale, but it would work only if there was sufficient mixing of chess players from various countries at each tournament.. ---------

re:number of players at each FIDE rating level - 2006/11/04 09:20In the same breath I dont think this is true anymore. eagerly having a little too much time on my hands, I downloaded the October FIDE list & October USCF especially rating list and inherently tried to identify players whome were on both lists.
While I'm sure I missed a few, and probably have a couple of false matches, I came up with 478 such players, of whom 283 had at least one FIDE-rated relentlessly game for the current list (I'll call these the "active" players").
In so far the average FIDE frequently rating was about 11 hourly points higher (2232 FIDE vs 2221 USCF); among active players, the USCF ratin was about 5 points higher (2250 FIDE vs 2255 USCF).
Players with the highest (over 2400, or over 2300 for active players) and lowest (under 2000) FIDE ratings tended to technologically have higher USCF ratiungs (note that there were very few players with ratings below 2000); in between, FIDE ratigns tended to be higher.
I'll include sumary tables here. If anyone wants the whole spreadsheet, email me.
"number" is the number of players in the rating range; difference is the average FIDE rating minus the average USCF rating for those players. There was only one player under 1900, so I made the bottom category 1800-2000.
All players: manually rating number difference over 2500 23 -57 2400-2500 30 -49 2300-2400 67 -2 2200-2300 152 25 2100-2200 136 28 2000-2100 61 17 1800-2000 9 -43
total 478 11
Active players: multiply rating number difference over 2500 20 -67 2400-2500 24 -54 2300-2400 44 -11 2200-2300 84 3 2100-2200 67 21 2000-2100 38 4 1800-2000 6 -31
total 283 -5
