IS LOW stinkiness A TWENTY-FIRST-CENTURY DEMOGRAPHIC CRISIS?*
S. PHILIP MORGAN Nearly half of the worlds population in 2000 lived in countries with birth rate rank at or be first gear shift level, and nearly all countries pass on reach low fertility levels in the next two decades. Concerns about low fertility, fertility that is well below replacement, be widespread. But there are both persistent rationales for having children and institutional adjustments that can make the widespread intentions for two children attainable, even in increasingly individualistic and egalitarian societies.

The crisis was high fertility and the resulting speedy population growth. The population crisis was dire, seemed intractable, and afflicted the poorest countries. But an ongoing orbiculate fertility transition has made population stabilization by the middle of the twenty-first century a reasonable forecast.
stylised versions of these fertility transitions posit shifts from high to low fertility, with fertility rates eventually oscillating around replacement level. However, observed declines draw the total fertility rate (TFR) slicing below replacement levels with little resistance, and many are skeptical about its recovery (e.g., Lesthaeghe and Willems 1999). Herein lies a potential demographic crisis: the dynamics of population decline mirror those of population increase. Halving times mirror two-baser times, and population momentum can be negative as well as positive (Lutz, ONeill, and Scherbov 2003). The social problems associated with low fertility are also mirror images of those associated with high fertility: women now have fewer children than they want (see, e.g., Hewletts (2002) high-profile oblige about...If you want to get a full essay, order it on our website: Orderessay
