What Is Unique about Kerala? Beautiful beaches, red sands, coconut trees and people full of love… 33 million people occupying an area the size of Kentucky. One of the most densely populated region in the world. Banana trees and rice paddies, eastern Kerala, India.

In Brief, This Chapter Is About • Improving the lives of people • Reducing fertility rates • Protecting the environment
6.1 Reassessing the Demographic Transition 3 Key Points International Conference on Population and Development (1994): • Development must be linked to a reduction in poverty • Existing poverty is an affront to humanity and should not be tolerated • Both poverty and development are threats to the health of the environment
6.1 Demographic Transition: Developed and Developing Countries • Developed countries:decrease in birth rates along with decrease in death rates rapid growth never occurred. • Developing countries: birth and death rates remain high until mid-1900s. Modern medicine caused drastic drop in death rates, but birth rates remained high rapid population growth.
6.1 The Demographic Window As countries experience gradually decreasing fertility, the dependency ratio (working-age population relative to non-working age) declines and opportunities fordevelopment increase. Society can put in place population and economic policies that are consistent with poverty reduction and economic expansion. Can spend less $ on new schools and old-age medical expenses…
6.1 Fertility Rate and Income There is a correlation between income and lower total fertility. Factors that affect fertility more directly are health care, education for women, availability of information and services related to contraception.
6.1 Reasons for Large Families in Developing Countries • Old age security • High infant and childhood mortality rates • Children are an economic asset (“helping hands”) • Low importance of education • Status of women (depends on # of children she bears) • Availability of contraceptives
6.1 The Poverty Cycle • Increasing population density leads to a greater depletion of rural community resources • firewood, • water, and • land, • Encourages couples to have more children to help gather resources, and so on…
6.1 Discuss Interrelationships of Factors Influencing Family Size How does each country view the following factors? • Importance of education and children viewed as economic assets or liabilities • Status of women and importance of education • Income and old age security • Cultural views on child-bearing • Contraceptive use and availability
6.1 Contraceptive Prevalence and Fertility Rates More than any other single factor, lowering fertility rates are correlated with the percentage of the population using contraceptives. Each 12% increase in contraceptive use translates into one less child. Fertility Rate Percent Using Contraceptive
6.1 Contraceptives • Psychological/Behavioral: abstention, calendar rhythm method • Mechanical: condoms, diaphragms • Chemical: the pill, Norplant, sponge, spermicide cream • Surgical: tubal ligation, vasectomy • Intrauterine Devices (IUD): abortion device
6.1 Contraceptives: Vasectomy No-scalpel technique, the abdominal and testicular ends of vas is identified through a small puncture hole for microscopic reconnection. (Conventional technique makes a large incision and delivers testis out to identify both ends of vas and make microscopic reconnection.
6.1 Adult Female Illiteracy: A Global Comparison • Social structure in developing countries discourages/bars women from obtaining a higher education, owning land, owning a business, pursuing a career • Forces women to do the only thing they can dobear children RESPECT!
