For Ireland, information is available for 2005 and 2006, which shows a popularity rank of 10th and 14th, respectively, for use of "Ryan" as a male given name for newborn children.
In Scotland of the 1990s, "Ryan" was the most popular forename of the decade; this popularity is recent, as "Ryan" apparently was not in use in 1900, ranked between 100 and 250 in 1950, and appears at rank 64 in 1975. In Northern Ireland, "Ryan" appeared among the top-five most commonly selected male names for newborns in 2000–2003, but did not appear among the top-ten in 1975. In England and Wales, data for 2003–2007 is available, which suggest somewhat less popularity of "Ryan" than in other parts of the UK, having a rank of 21 in 2003 and 2004 then dropping to 25 in 2005–2007.
"Ryan" as a male given name has persisted in popularity for the thirty-year period of 1976–2006 in the 10th to 20th rank; the name appeared in the top-thousand for the first time in 1946 and gained steadily in popularity until leveling off in the 1970s. The popularity of "Ryan" as a female given name is an order of magnitude less than that as a male name; the name first appeared in the top-thousand in 1974 and has remained there since, fluctuating widely from year to year but never breaching the rank of 300.
