I had considered adding an income type to the survey, however knowing how I feel about such questions and the relative worth of the question for my purposes and the chance of having a number of people not respond to the survey because of that, I elected not to include it. Another reason I did not do it was because it would only document the income of techdiver-l subscribers and not techdiving population at large which has been done. I think we could draw some general inferences based on education if we wanted to. At Aqua-Corps 93 TEK Conference a survey was made that had a few results which were interesting, namely how much people had invested in diving equipment. Aprox. 22% had between $7500-$9999 US invested. Aprox 18% had between $10,000-$19,999 US and 10% had between $20,000- $29,000 in equipment! Another 12% had over $30,000 in equipment with 6% of that having over $50,000. Their survey broke down income as follows: (I'm reading this off a bar chart) <25,000 5% 25-50,000 45% 50-75,000 +-22% 75-100,000 15% 100,000+ +-12% One point that survey made was that techdivers make up 7-10 percent of the overall population but account for approx. 40% of the installed base of equipment and 30% of the annual dive spending in the US! If those results are valid, I think it fair to assume that techdivers are affluent and or are some sort of monk society where they (we) have absolved ourselves of all worldly goods except for dive equipment (;-> Where I noticed a variation between the Aqua-Corps survey and the one done here was that the techdiver-l subscribers are better educated. Frank continues: >Also, re-reading your new survey notes, I am curious if techdivers are a more >insured group than ordinary sport divers, and how the treatment refusal rate >for DCS compares with the larger sport diving population...(....) Interesting points. I have never seen any figures on the latter. Perhaps if the readers didn't object, we could address your points in a seperate survey at a later date?

Ok, this is a case where figures and common sense go off in seperate directions. The results, if litterally taken, say that 6.52% of the divers have never made an open water dive, ever! I really don't think that's the case. This error came about because several folks left the answer blank and some failed to respond to any of the questions That is why I noted that the percentages had to refer back to the total population of 46 otherwise all the results would indicate a 100% participation and that is why I also indicated the number of responses in each catagory.
