The problem of the differences in the propensity of some to respond as a function of their age is addressed in statistical sampling theory as the
non-response problem. To obtain unbiased estimates of the age distribution (as I suspect the younger members may be potentially more likely to
participiate than older members), one must subsample the non-response population. One way to accomplish this is to send out U2Us requesting a private
response from those who not responded.
There are also more statistics out there that may be of value (to an economists, for example) including the world's age distribution, or just in the
developed countries, the ranking of those countries in math and science, per capita spending on education, per capita income, smart phone sales as a
proxy for computer access,...
You also may want to add some chemistry questions to provide a more meaning survey to assess the potential ability of a member to contribute. For
example, do CH4, Cl2 and water vapor normally react? Does NH3, I2 and water vapor normally react? Are all of the following stable in the presence of
pure water only: Ag, Au, and Pt? Others may alternate questions or views on the appropriateness of adding just knowledge based questions.
