Reasons why a developing country should strive to reduce its high birth rate?

The anwer to this question is more properly determined if the countries type of government is known. A high Birth Rate would affect different types of governments in different ways as a developing country would also be affected by the type of country it was, and how developed they actually are. A country going through an industrial period would be affected differently from a country who has a stake in the global market, or one which is still driven by agricultural commerce. I will answer in regards to the only government I have ever experienced myself, the democracy of the United States of America. 1. An increased birth rate would cause an increase in health care costs, and consequentially, any other costs which could be associated with the current age and development of the population boom generation. (i.e. the baby boomers). Developing countries are defined in part by the average income of an average citizen, and unless a country has a thriving economy to produce jobs for the increase in population numbers, the ultimate result will be a plateau and eventual decline of the economy. Population and economical growth have always been defined as a product of one another. When one levels out, so does the other. 2. An increased birth rate would cause an increase in the amount of representatives who are employed within the house of representatives. As the increase in birth rate would ultimately result in an increase in the average number of voting aged citizens, this would lead to an increase in the amount of politicians each state can employ to represent them within the House of Representatives in Washington, D.C. (This is currently happening in Utah, as they are seeking to expand from three to four districts, gaining one more representative seat in Washington, D.C.) As previously mentioned, these answers are solely based on the type of economical commerce and government the country employs. Answers will vary due to each scenario.
