According to me, it means that if education level increases or spreads then income also rises due to more job opportunities but fertility fall means that people will not concentrate on making their family large ie they will not have much reproduction of their young ones.... and hence parents will take proper care of their single or double child much better...and hence health rate also increases and development will be the best
