The findings of the paper show that level of economic growth and demand of insurance services in all states varies: the insurance density in Lithuania last year was at 1,6 %, while the average cost of insurance per capita was 204 euros. Latvian insurance market penetration and density was respectively 1,5 % and 185 euros, Estonian 1,7 % and 259 euros, Slovenian -5,1% and 920 euros, while the average penetration and density in the EU countries of Central and Eastern European region was 2,6 % and 334 euros.
