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.

Population growth increases labor force and, thus, increases economic growth. A large population also provides a large domestic market for  the economy. So we can easily say that, population growth encourages competition, which  generates technological advancements and innovations.
