The National Marriage Project, joined by universities in five nations, has published The Sustainable Demographic Dividend--a report that links the strength of families and the economy.
“A turning point has occurred in the life of the human race,” the report found. “The sustainability of humankind’s oldest institution, the family—the fount of fertility, nurturance, and human capital—is now an open question. On current trends, we face a world of rapidly aging and declining populations, of few children—many of them without the benefit of siblings and a stable, two-parent home—of lonely seniors living on meager public support, of cultural and economic stagnation.”
... the number of children age 0–14 is 60.6 million less in the developed world today than it was in 1965.
