A genealogical myth that surfaces occasionally is that genealogy/family history is the most popular, or in some versions most rapidly growing, hobby. Hard evidence is scarce as 17th century census data.
Now Stephen Abrams has posted a blog item, rankings from a survey of a group of librarians on the most asked questions about hobbies.
One could question the inclusion of some of these items as hobbies, such as religion and spiritual activities.
While genealogy is way down on the list, below many traditional hobbies such as reading, gardening, arts and crafts. With the exception of exercising, walking and cycling, genealogy comes in ahead of sports of all kinds, both amateur and professional, which receive huge government subsidies.
