The correct answer to this open question is the following.
The Trait Theory of leadership contends that leaders are both born and made. What this means is those good leaders have a series of qualities or characteristics needed to lead their teams successfully.
The Trait Theory was developed by researcher Thomas Carlyle in the mid of the 19th century. He considered that some traits create some patterns of behavior. The research suggests that many of our leadership skills are innate, which means people born with those skills. However, Carlyle thought that leadership abilities also could be learned. We are talking about traits such as courage, creativity, flexibility, decisiveness, adaptability, self-confidence, and perseverance.
Our society has a very conservative thinking. We all know that according to Hindu religion especially male are prioritized than that of women. Women are not given much importance. So many people wants at least one son in his/her family. They keep on trying for a son rather than daughters. Moreover when they get a daughter instead of son they still keep on trying for sons.
People also have a thinking that children are gift of gods. So , people keep on bearing more and more children which results in population increase.
Hence we can say that social values and traditional thinking are helping to increase population.
