Number of sports tools and the degree of popularity of the sports

* Number of sports tools and the degree of popularity of the sports

From the 2012 London Olympics, baseball and softball was excluded from the official competition. The reason is that "there are few participating countries." Certainly, even in the 2006 WBC, there are about 10 participating countries such as the United States, Japan, Cuba, and South Korea. Seems not many.
Therefore, count the number of tools required when playing a certain sport, and try to relate it to the competitive population. A field is a place to compete, which is also counted. Then, roughly

Soccer: Field, ball, goal ... 3 pieces
Baseball: Field, ball, bat, mitt (* 2), glove, base (* 4)
Helmet, hat, protector, mound plate ... 14 pieces
Judo: field, dogi ... 2 pieces
Marathon: ... field ... 1 piece
Golf: Field, ball, hat, various sticks ... 10 pieces

It will be. Baseball (or golf) uses a large number of tools. Therefore, in order to play baseball, you have to prepare the tools, so you can only play baseball if you have a certain level of income. If you go there, you don't need any tools other than the field for a marathon, and you can practice soccer if you have a ball. Therefore, it is presumed that sports with fewer tools are more likely to be accepted by poorer countries and have a larger competitive population.

In order to quantitatively show the above considerations, I asked the JOC about the "number of countries participating in the competition at the district qualifying level at the Athens Olympics" for the above four competitions (excluding golf). The competition population is estimated based on the number of participating countries. However, this kind of information is different from my purpose because it is information about who won the gold medal without looking at the net. The response from the JOC was that there is no data, please contact various sports organizations. When I contacted the Japan Football Association, he asked me to ask FIFA. I was turned around. It was a typical government office job.

For judo, I contacted the Kodokan and asked them to tell me the number of countries participating in the 2002 Osaka World Championships. 97 countries. It was a clear answer. “One win !” Then I contacted the Japan Association of Athletics Federations for the marathon. It's quite difficult to count, so when I asked them to send me the raw data of the nationality information of the participating athletes, I counted 64 countries. For baseball, 16 countries are assigned to the number of WBC participating countries. Regarding soccer, 16 countries participated in the main race, and 110 countries were estimated from the data of 3 countries in Europe and 2 countries in South America and the number of countries in the region. (Therefore, marathon and judo are real numbers, soccer and baseball are guesses.) Golf was not an Olympic event(as of 2011), so I set it to 0 countries. It's a bit unfair, but even if the competition population is large, I'll give you an example where there are many tools, not an Olympic event.

The above results are made into a table and a graph.

Competition, number of participating countries, tool number

Marathon 64 1
Judo 97 2
Soccer 110 3
Baseball 16 14
Golf  0  10


When the number of participating countries is on the horizontal axis and the tool stand is on the vertical axis, points are plotted, and the regression line and correlation coefficient are calculated.

(Regression line) Y = -0.0969X + 11.6
(Correlation coefficient) -0.824

It can be seen that the number of participating countries tends to increase as the competition has fewer tools. It also gave a fairly strong correlation. My hypothesis has been proved.
If the above considerations are correct, it seems natural that baseball and softball will disappear from the Olympic events.

A word of the day: Even so, even if you try to verify your own ideas, the Internet is powerless if people with similar interests do not leave data.
