A recent blog survey by Perseus revealed that the majority of bloggers are women (56%) but a new survey by Pew Internet shows that 57% of all US blog creators are men. The two studies were performed quite differently. Pew made two telephone surveys with in total 1,861 internet users in the US, while Perseus surveyed 3,634 blogs on eight leading blog-hosting services. Perseus analysis “does not cover nonhosted blogs – blogs that individuals maintain on their own servers using their own tools”.
I am not an expert on statistics but it seems that Pew’s survey draws conclusions from a very small number of respondents. If they surveyed 1,861 internet users and 7 per cent of them had created a blog, that is only 130 people (74 male, 56 female).
