Brazil has become one of the developing world’s great successes at reducing population growth—but more by accident that 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.
Martine puts it down to, among other things, soap operas (通俗电视连续剧) and instalment (分期付款) plans introduced in the 1970s. Both played an important, although indirect, role in lowering the birth rate. Brazil is one of the world’s biggest producers of soap operas. Globo, Brazil’s most popular television network, shows three hours of soap
A. haven’t attached much importance to birth control
B. would soon join Brazil in controlling their birth rate
C. haven’t yet found an effective measure to control their population
D. neglected the role of TV plays in family planning
