229982 men total in Finland have the name 'Olavi' according to (http://verkkopalvelu.vrk.fi/Nimipalvelu/default.asp?L=3) and is currently one of the very popular names within the whole entire population of Finland, ranking at third place below Johannes and Juhani. In 2010-16 9595 baby boys were given 'Olavi'. In 1940-59 75598 men were given 'Olavi' making it the time period 'Olavi' was most used. Long ago in the 1800's it wasn't really that popular until the 1900's and I can tell this name is still very popular today, but not as popular as it was back then.
