Taiwan's population has fallen for thirty-two consecutive months. Data released by the authorities show births continuing to run below deaths.

Fewer marriages, a rising age at first birth and the cost of housing and child-rearing are cited together as background. Most analysis treats it as a structural trend that no single factor explains.

Changes in the age structure affect labour supply and social insurance finances with a lag. A shrinking school-age population has already prompted discussion of consolidating some schools.

The authorities have responded chiefly through child-rearing allowances and expanded childcare provision, though experience elsewhere suggests a long interval between such support and any rise in births.

Immigration and residence policy form another strand of the debate, with industry citing labour shortages in calling for adjustments to rules on foreign workers.

The statistics are published monthly and fluctuate with seasonal factors, but a run of thirty-two months is difficult to explain as short-term variation.
