But without any context, that information isn't much use, is it? If someone says they only build one site per year, how useful is it to know that without any more information? You can't really conclude anything from that information without further information about the person's circumstances. Perhaps they work as a brick layer, for example, and just for fun sit down once per year to put up a simple site as a hobby. Without that kind of context, you could conclude that, on average, people only create one site per year.
Anyhow, I don't mean to criticise, but was asking in case this was for some kind of research project—in which case, you'd need a more thorough survey.
