Based on the research by UNFPA, the most significant factor in reducing birth rates is wealth. Wealth, however, seems to speed growth and the need for more and more natural resources. An interesting paradox which might lead to disaster. It does of course explain many things such as the fact that the most popular name given to newborns in Belgium is Mohammed. I suspect that there are models that address birth rate and growth issues. Happy Holidays Paul Paryski
