It might seem hard to defend Sepp Blatter, the FIFA president who announced his resignation last week in the wake of a global soccer corruption investigation by the U.S. Department of Justice.

But a few brave souls have tried. Branko Milanović, a developmental economist at the City University of New York Graduate Center, wrote that while FIFA’s corruption may be regrettable, the decentralization of power under Blatter has at least contributed to the “spread of the game to the rest of the world” beyond the traditional European and South American soccer powers.

FIFA’s governing structure and its corruption are clearly related. Through its “one country, one vote” principle and its policy of allocating development funds fairly evenly across countries — Comoros and Brunei get about as much money from it as China and Brazil — Blatter can command the loyalty of a majority of FIFA’s members even if they represent a minority of the world’s population, soccer audience and soccer revenue stream.

But here’s the problem. Despite FIFA’s having earmarked more than $2 billion in soccer development funds under Blatter, there’s no evidence that the soccer playing field has become more level — at least not when measured by success on the pitch. In international play, the European and South American countries are as dominant as ever, while Africa has made little progress and Asia has perhaps regressed. Nor is there any evidence that poorer countries have become more competitive in soccer relative to wealthier ones. If anything, the disparity has grown since Blatter became president in 1998.

The rest of this analysis will be pretty simple. We’ll compare the Elo rating for each country’s men’s national team as it was on June 8, 1998 — the day Blatter took over as FIFA president, a few days before the 1998 World Cup — to what it is now. (For more background on Elo ratings, see here. Higher ratings are better, and 1500 represents an average team. You can find all of the data we’re using in this article at GitHub.)

First, we’ll look at performance by region, with countries divided according to the six continental confederations under FIFA. For each confederation, we’ve listed Elo ratings for the 10 largest countries in descending order of population, along with the confederation average, weighted by population.

Europe (UEFA) and South America (CONMEBOL) remain the dominant soccer continents. Although some individual countries in Europe (Germany, Turkey) have improved their national teams since 1998 and others have seen them decline slightly (Italy, Russia), the continent as a whole has seen little overall change under Blatter. UEFA’s average Elo rating, weighted by population, is 1793, almost identical to its 1797 rating when Blatter took over.

South America, however, has improved considerably. Although Brazil’s Elo rating is not much changed from where it was in 1998, five of the 10 CONMEBOL countries (Argentina, Chile, Colombia, Venezuela and Uruguay) have improved their Elo rating by more than 100 points. This is interesting given that CONMEBOL is poorly represented under “one country, one vote,” representing 4.8 percent of FIFA members but 13.5 percent of the World Cup audience.

But what about the rest of the world?

The closest thing to a success story is the North American confederation, CONCACAF, which has improved its Elo rating by a population-weighted average of 61 points since 1998. Partly that reflects the continued development of the U.S. and Mexican national teams, since the United States and Mexico represent more than three-quarters of CONCACAF’s population, though other members of the confederation have improved on average too. Still, while that might be good news for North American soccer fans, it doesn’t help Blatter’s argument that he’s helped spread the wealth: CONCACAF has the highest per capita GDP among the six confederations.

The poorest confederation, by contrast, is Africa (CAF), but it’s shown little improvement soccerwise. In the 2014 World Cup, its countries combined for three wins, three draws and 11 losses. The 2010 World Cup, held in South Africa, wasn’t much better, with only Ghana advancing to the knockout stage among the six African entrants. Overall, Africa’s combined Elo rating is 1483, no better (indeed, slightly worse) than it was 17 years ago.

Asian (AFC) teams seemed to have nowhere to go but up in 1998, with a continental average Elo rating of just 1323 when Blatter took over. The expansion of the World Cup from 24 to 32 teams in 1998 doubled the number of Asian participants, and the continent was host to the World Cup for the first time (in Japan and South Korea) in 2002. Instead, however, Asian nations have mostly seen their performance decline. Of the 45 AFC members to field a national team in 1998, 28 have a lower Elo rating now. This includes the two most-populous countries in the world. China’s men’s team has stagnated, still having qualified for the World Cup only once in its history (2002), while its women’s team, once the major global rival to the United States and Germany, has regressed. India, meanwhile, hasn’t come close to qualifying for the World Cup for many years, a description that also holds for other poor but populous Asian countries such as Indonesia, Pakistan and Vietnam.

Finally, in the Oceania confederation (OFC), New Zealand has improved its performance since 1998, while the other, poorer members of the confederation have declined on average. (Australia, which defected from the OFC to the AFC in 2006, is counted under Asia instead.)

As a sanity check, I’ve also listed the World Cup record of teams from “the rest of the world” — that is, CONCACAF, AFC, CAF and OFC — in matches against Europe and South America. In the five men’s World Cups contested under Blatter, the rest of the world had 25 wins, 42 draws and 98 losses against Europe and South America, accumulating 0.71 points per match. That’s slightly worse than the final three World Cups, 1986, 1990 and 1994, under Blatter’s predecessor João Havelange. And while progress was steadily upward under Havelange — points per match for the rest of the world increased in each World Cup from 1974 through 1994 — their best performance under Blatter, 2002, is now four World Cups behind us.

Nor have poorer nations improved their performance relative to wealthier ones. The next chart divides countries into quintiles based on their per capita GDP and tracks how their Elo ratings have changed since 1998:

GDP PER CAPITA PERCENTILE AVERAGE ELO CHANGE, POP. WEIGHTED 80-100th +15 60-79th +34 40-59th +4 20-39th -34 0-19th -8

There’s not much of a pattern. But if anything, the wealthier countries have gained ground on the poorer ones. The top two quintiles (the richest 40 percent of countries) have seen their Elo ratings improve by a population-weighted average of 24 points, while the bottom two (the poorest 40 percent) have seen them decline by 30 points. In particular, a number of high-population countries that rank somewhere between the 20th and 39th percentile in per capita income, like China, India, Indonesia and Nigeria, have failed to improve their soccer programs at all, at least judging by their results in international play.

One last question. Have low-population countries gained ground relative to high-population ones? It’s not clear that this is a desirable outcome, but it might be what we’d expect given that under Blatter, FIFA has allocated developmental funds almost without regard to population. (A few million dollars should go much further in a country of 500,000 people than one of 50 million.) But there’s no evidence of this either. Countries with a population of less than 10 million people had an average Elo rating of 1280 in 1998; it’s virtually unchanged at 1283 now.

Perhaps FIFA’s development funds are too small to make a difference. Or perhaps, given the corruption in the organization, a lot of the money earmarked for soccer development is being used to enrich local plutocrats at the expense of their countries’ soccer programs.
