I'm familiar with LR mostly as it relates to colonization of low-LR provinces in comparison with my "min LR". But I'm wondering what advantages the higher LR provinces have. From reading threads around here, I get the impression it somehow helps natural population growth. In my own testing I've discovered it also plays a factor in where foreign immigrants choose to go. But I'm wondering if people know more of how the mechanics of it work and what all of the effects of LR are.
