A little early, but the infographic above (sixth in the series) shows solar car teams that are likely to be entering in the World Solar Challenge this October, with my estimate of reported current progress (on a red–amber–green scale), taking into account recent social media updates. At this stage, almost all teams have posted evidence that a solar car is being built, and I am expecting about 44 cars to turn up in Darwin this October. Several teams (most recently, Michigan) have also announced the name of their car.The team list has also been updated, and has a simpler traffic-light version ( ) of these estimates, together with more detailed news.
Lately I’ve been exploring demographic and social data, including looking at the Australian data in the World Values Survey. Of particular interest are data on self-reported happiness. Among women, financial stress and poor health contribute to unhappiness, as might be expected. Socially conservative women report being happier, and single women report being less happy. Finally, women who attend religious services once per week or once per month are happier than those who do not attend religious services, or those who attend religious services more than once per week. This is broadly consistent with literature on the effects of religion on mental health.
Among men, financial stress and poor health act in the same way as for women. In terms of marital status, however, it is separated men who are the least happy. Male happiness is also closely tied to employment status, with unemployed (and, to a lesser extent, self-employed) men reporting more unhappiness.
Lately I’ve been exploring demographic data related to women’s health. Among other things, this involved looking at the Australian data in the World Values Survey, which includes a self-reported measure of health. For women, this depends on a number of other variables, including age:
For men, the age effect is weaker:
Presumably, this is because male health problems are more likely to be fatal, which is why there is an excess of women amongst the elderly, as indicated by Australian census data:

Sometimes we are just fooling ourselves. Nothing good comes of that.
