I have compiled a world ranking using the IIHF model for both the U20s and a combined junior (U20 + U18, equally weighted) over the last 25 years.
Please note the Canadian and American rankings prior to 2004 in the combined ranking aren't really relevant because they only participated in the U20 in parts/all of the 4 years prior.
It gives you some indication of how nations are progressing or regressing. Look at Ukraine in the year 2000: 7th in the combined and 10th in the U20. Whereas someone like Denmark were 16th in the combined and 20th in the U20 in 1998.
In 1991, 7th through 14th in the U20 were:
Norway, Switzerland, West Germany, Poland, Japan, France, Romania and Denmark...
