Highly developed countries, such as the U.S., Canada, France, Germany, Sweden, Australia, and Japan, "have low rates of population growth and are highly industrialized relative to the rest of the world." Lowest birth rates and low infant mortality rates, or the number of infant deaths under the age of 1. long life expectancies, high rates of energy consumption, and high waste production. The fertility rate in developed countries is 1.9. Developing countries can be divided into two categories: moderately developed and less developed. Moderately developed countries include Mexico, Turkey, Thailand, India, and most South American nations whereas less developed countries include Bangladesh, Niger, Ethiopia, Laos, and Cambodia. Moderately developed countries have higher birth rates and infant mortality rates than those of highly developed countries. fertility rate is around 2.4; the life expectancy is about 75 years, and about 62% of women use modern contraception.Less developed countries have the highest birth rates, the highest infant mortality rates, and the shortest life expectancies. But, these countries have lower levels of fossil fuel usage and waste production. Less developed countries have a fertility rate of approximately 4.8 and the life expectancy is around 62 years. Gender inequality is prevalent in most societies but the extent of gender inequality varies in different cultures. In developing countries, more women than men live in poverty and in most countries women are not guaranteed "equality in legal rights, education, employment and earnings, or political participation." As mentioned in the previous question, sons are oftentimes valued higher than daughters causing girls to be kept at home instead of being sent to school. Women are also limited to low-skilled and low-paying jobs due to certain laws, customs, and lack of education. In these types of societies, women may only achieve social influence and economic security through marriage. Therefore, the low status of women is the "single most important factor affecting high total fertility rates." If the social and economic statuses of women are improved, then unsustainable population growth may be controlled.
