Furthermore, it is clear that infrastructure and services have not kept ahead of population growth and is reason enough for concern. In response to Evenson's question 'So what's the answer?; I would suggest that reproductive healthcare and education is not 'tried and failed' but tried and tested, as proven by the fertility rate of 1.8 across the high income countries.
