What special demands does a high birthrate put on a nation's economy?

Rising birthrates can both improve and damage a national economy. A high birth rate requires good health facilities, advanced team of nursing and advanced technology in hospitals that ensures a smooth birth process. Moreover the since the population would be rising there is going to be extra demand for food, shelter, schools etc.
