Washington D.C, Mar 29 (ANI): When the cost of achieving social status goes up, the fertility goes down, according to a recent study.
The Emory University research suggested that competition for social status may be an important driver of lower fertility in the modern world.
Senior author Paul Hooper said that the areas where the greatest declines in fertility are seen are the areas with modern labour markets that have intense competition for jobs and an overwhelming diversity of consumer goods available to signal well-being and social status.
The anthropologist added that the fact that many countries today have so much social inequality, which makes status competition more intense, may be an important part of the explanation.
The study authors developed a mathematical model showing that their argument is plausible from a biological point of view.
Across the globe, from the United States to the United Kingdom to India, fertility has gone down as inequality and the cost of achieving social status has gone up. “Our model shows that as competition becomes more focused on social climbing, as opposed to just putting food on the table, people invest more in material goods and achieving social status, and that affects how many children they have,” Hooper says.
Factors such as lower child mortality rates, more access to birth control and the choice to delay childbirth to get a higher education are also associated with declining fertility. “While these factors are very important they are insufficient to explain the drops in family sizes that we are seeing,” Hooper says.
