“…in British Gardens. AT least one in 20 homeowners now has an outdoor heated water spa.”
Percentage of GB households with private gardens?
“Government forecasts seen by The Daily Telegraph show the percentage of households with gardens is expected to have fallen from 91.8 per cent in 1995 to 90 per cent by next year.”

I’m not sure I believe that either. but the story in question, based on a survey of 2000 homeowners carried out by OnePoll for Lloyds TSB insurance found that between 4% and 10% of homeowners have a hot garden tub. I can’t find the original release, but I guess it said that the figures was 7% with a 3% margin of error.

“By 2008 the industry reckoned it was selling 12000 a year”. 7% of 90% (households with gardens) of 25 million (GB households) =
900,000. 900,000 divided by 1200 = 75 years. Or to achieve 900k, we have 20 years (guesstimate) at 12000, but a five year constant rate of increase such that last year 350,000 were sold (too boring to show the working but available to interested parties).

Crapstat rating: 2.

Straw poll of one: I haven’t got a hot tub in my garden, but if I did I would spoil the view of about 20 neighboring households whenever I used it.
