Slavic Native Faith underwent dramatic growth in Ukraine during the early and mid 1990s. In 2005, Ivakhiv noted that there were likely between 5000 and 10,000 practitioners in Ukraine. Three years later he reported sociological researches suggesting Ukrainian Rodnovers to be 90,000 or 0.2% of the population. The religion's "main base" consisted of ethnic Ukrainians who were "nationally oriented" and who displayed higher than average levels of education. There is overlap between Slavic Native Faith followers and other sectors of Ukrainian society, such as the folk and traditional music revival groups, Cossack associations, traditional martial arts groups, and nationalist and ultra-nationalist organisations.
