Fact - if a data set can be split into two groups, both of which have at least the ratio a:b for some 2 characteristics, then the entire data set has at least the ratio a:b for those 2 characteristics.
The corollary for above:
if a data set can be split into two groups, and one of the groups has a ratio HIGHER than the overall ratio for some 2 characteristics, then the other group has a ratio LOWER than the overall ratio for those 2 characteristics - and vice versa.
