This link is talking about the expansion of women's spending power in Korea. One of the topic they talking about is the increase of female fans in 4th gen girl groups fanbase.
"This phenomenon also appears in the music market. Changes are being made to encourage more purchasing power among K-pop female fans. In the overall K-pop market, women's purchasing power has previously been higher. Looking at sales data from Interpark's own goods shop, 'Ticket MD Shop', it was found that 9 out of 10 customers who purchased goods such as program books and badges at the concert hall were women.
Meanwhile, the gender ratio of female consumers purchasing albums from 4th generation girl groups New Jeans and Ive was also found to be very high. As the influence of female consumers with purchasing power is so strong, efforts are in full swing in the popular culture world to capture so-called 'female fans'.
Unlike existing girl groups that had a high proportion of male fandom, the proportion of female fans in 4th generation girl groups (New Jeans, Ive, Le Seraphim, etc.) is as high as boy group idols. 4th generation girl group songs mainly contain lyrics about women's independence, confidence, and self-esteem.
'Subject me' is not necessarily a story limited to women, but it can be seen that women were set as the central target through lyrics that resist taboos and oppression and pursue freedom, and this strategy can be seen to have worked well for female consumers."
This article main point is saying the changes in lyrics make the newer generation girl groups more accepted by female fans. But is it the only reason? Why this generation girl groups attracting more fangirls than fanboy?
