The one statistic I never understand

How wonderful are your local Yakuza? graph of japanese opinion
Regardless of how long I live here, and how often people try to explain the Yakuza to me, I always shake my head in disbelief when I see stories like this one on the guys who put the Organised into Organised Crime.

Crime syndicates in Japan had around 86,300 members as of Dec. 31, down some 700 from a year earlier, marking the first drop in 10 years, the National Police Agency said Thursday. The Kobe-based Yamaguchi-gumi, accounted for 50.1% of all the members, passing the majority threshold for the first time.

What sort of questionnaire got these answers? Do the gangs submit annual reports? I can only imagine the text: “The chairman reports that outstanding bad debts are down 22.9% due to a 16.3% increase in the number of kneecaps broken. Workforce loyalty is also strong, as indicated by a two-thirds reduction in pinkie removals.” Three significant figures of accuracy suggests relatively detailed numbers are being obtained from somewhere, but where?

Note that the graph above may not, in fact, be truthful. In fact, I may very well have made it all up!

International marriage still means Japanese man and Asian woman

I obtained some figures of international marriage in Japan, which I shall summarise here, giving the historical trends from 1985 to 2003. The exact source of this statistical data is unclear, but presumably from some government agency.

UPDATE: I found the source, an Excel sheet on the Ministry of Health, Labour and Welfare web site.

  1985 1990 1995 2000 2001 2002 2003
All couples 735,850 722,138 791,888 798,138 799,999 757,331 740,191
