Prior state
Fertility had fallen but remained above the ultra-low levels characteristic of East Asia.
Material change
Period fertility in major urban centers of the named regions reaches or falls below the ultra-low range previously associated primarily with East Asia, producing earlier and sharper cohort declines than previously projected.
Why now
Rising education and opportunity costs of childbearing, housing constraints, and changing partnership norms diffuse rapidly once a critical share of urban cohorts experiences them.
Mechanism and resistance
Governments introduce modest pronatalist incentives; cultural and religious norms slow the decline in some communities; the economic and status incentives for delayed and reduced childbearing remain powerful.
Consequences
The demographic transition accelerates; future labor-force and care pressures appear earlier than in previous projections; political attention to family policy increases.
End state
Ultra-low period fertility becomes characteristic of major urban centers across additional middle-income regions.
Observable test
National or urban vital statistics showing period total fertility rates at or below the ultra-low range previously observed in East Asia for consecutive years.
Disconfirming sign
Stabilization of urban fertility at higher levels without further decline into the ultra-low range.
