Here’s a bit of a short survey that has rather interesting results; iShare looked at the end of the year Jumbo Lottery.
Demographics
Between the 21st and 25th of November 2008 430 members of the CLUB BBQ free online email forwarding service completed a private internet-based questionnaire. 50.5% of the sample were male, 13.3% in their twenties, 54.4% in their thirties, 23.5% in their forties, and 8.8% in their teens or fifty or older.
First a lottery tip: if you can spare 300 yen, buy just one ticket. This measurably changes your odds from absolutely zero to infinitesimal. Buying a second leaves your odds still infinitesimal, so don’t bother.
Next, the lottery does seem to have a lot of misconceptions surrounding it, mainly focussing on the drawing method and the relatively small first prize, leading many to think that it’s even more of a tax on the innumerate than the average one. However, the term “lottery” is misleading, as most people imagine the pick six from fifty-type schemes that are prevelant in the west, whereas Japan’s is more like a raffle – all the sold tickets go into a hat and winners are drawn from there, so if it is a sell-out all the prizes (in theory) will be claimed.
This year there are 70 first prizes of 200 million yen (roughly 2 million US dollars), 140 almost-first prizes of 50 million yen, 6,930 almost-almost first prizes of 100,000 yen, 140 second prizes of 100 million yen, 700 at 5 million yen, and so on, assuming they sell all 70 blocks of tickets. In total, there are 700 million tickets for sale (about 6 per man, woman and child) for a total value of 210 billion yen. I make that just over 99 billion yen in prize money, or 47.3% of the sales, leaving just under 111 billion yen in the pot. Once television and print advertising, sales overhead, amakudari-inflated old-boy director salaries, and everything else are paid for, that leaves a little bit left over (can anyone point me to figures for administration costs on the lottery?) for good causes, but I have little idea what they fund.
Oh, there’s a headline figure of 300 million yen advertised as the top prize, but I’m not really sure how one ticket can get the extra 100 million.
So, back to the survey.
