type="main"> <title type="main">Summary</title> <p>We use the UK Labor Force survey to investigate whether the socio-economic outcomes of people born on the 13-super-th day of the month, and of those born on Friday the 13-super-th, differ from the outcomes of people born on more auspicious days. In many European countries, including the UK, number 13 is considered unlucky and Friday the 13-super-th is seen as an especially unlucky day. We find little evidence that people born on the 13-super-th or those born on Friday the 13-super-th are significantly less likely to be employed, earn lower wages or that they are more likely to stay unmarried compared to people born on other days.
