Demography as Destiny: The Vital American Family

New Geography reports:

Countries with the longest history of declines in fertility face the biggest fiscal crises. By 2050, for example, Germany and Singapore are predicted to have roughly 57 people above age 65 for every 100 workers. In the United States, this ratio will rise by 50 percent, to roughly 35 per 100 workers, even if the current decline is eventually reversed.
