Brazil has become one of the developing world' s great successes in reducing population

growth but more by accident than design. While countries such as India have made joint efforts

to reduce birth rates, Brazil has had better result without really trying, says George Martine at

Harvard.

Brazil' s population growth rate has dropped from 2. 99% a year between 1951 and 1960 to

1.93% a year between 1981 and 1990, and Brazilian women now have only 2. 7 children on

average. Martine says this figure may have fallen still further since 1990, an achievement that

makes it the envy of many other Third World countries.

According to Martine, both soap operas and instalment(分期付款) plans played an important role in lowering the birth rate. Brazil is one of the world' s biggest producers of soap operas. Global, Brazil' s most popular television network, shows three hours of soaps six nights a week, while three others show at least one hour a night. Most soaps are based on wealthy

characters living the high life in big cities.

"They described that middle and upper class values not many children and women

working. They influenced all parts of Brazil. " says Martine
