According to data from the Brazilian Institute of Geography and Statistics (IBGE), the fertility rate in Brazil has dropped significantly from 6.3 children per woman in 1960 to 1.6 in 2023. This trend is not isolated to Brazil; other countries, such as China, the United States, Chile, and Germany, are experiencing similar declines in birth rates driven by urbanization, economic crises, changes in lifestyle, and the growing participation of women in the workforce. As a result, there is a noticeable increase in the number of only children, a demographic change with various social implications.

Being an only child brings about certain privileges, such as not having to share attention, toys, treats, or space with siblings. However, the emotional and social aspects of growing up without siblings can lead to a sense of loneliness and a lack of companionship. While children without siblings enjoy independence and autonomy, they may also experience feelings of isolation, as they do not have someone to play with or defend them during conflicts at school or within the family.

The discussion around only children invites reflection on what one gains or loses when living without siblings. Although autonomy is a significant advantage, the absence of a brother or sister can lead to a silent yearning for companionship. As the article highlights, understanding this dynamic is essential in evaluating the broader implications of declining fertility rates and changing family structures in Brazil and worldwide.
