According to RhythmicAnalyst, the number of births per woman is strongly influenced by economic prosperity, the amount of time couples dedicate to child care, and an increased focus on lifestyle as wealth rises (source: Twitter, May 19, 2025). The thread highlights that in the past, the income-to-cost ratio made raising children more viable, but modern economic pressures and lifestyle priorities have shifted this balance. For cryptocurrency traders, shifting demographics and declining birth rates can signal long-term trends in consumer spending, investment patterns, and government policy. Lower birth rates may impact economic growth, which in turn could drive institutional and retail interest in alternative assets like Bitcoin and Ethereum as investors seek new growth opportunities (source: Twitter). Monitoring demographic and macroeconomic trends remains crucial for anticipating shifts in crypto market sentiment.
