Taiwan’s fertility rate stays among the world’s lowest on Tsai’s watch
Through 2023 Taiwan’s total fertility rate remained among the world’s lowest, a completed demographic spell across Tsai’s two terms despite housing, wage, and childcare instruments. In the causal graph this event strengthens Demographic ageing and labour-shortage pressure, a driver that strengthens International migrant stock (total, worldwide) — an improving welfare path.

Through 2023 Taiwan’s total fertility rate remained among the world’s lowest, a completed demographic spell across Tsai’s two terms despite housing, wage, and childcare instruments.
Context
MOI and DGBAS print vital statistics. She did not write a household formation statute by decree.
Housing unaffordability is a neighbouring household-formation row. Pension reform is a neighbouring fiscal-ageing row.
The president of the Republic of China (Taiwan) is head of state under the Additional Articles. She does not write a PRC statute, a US NDAA, a TSMC board minute, or a 2026 Lai cabinet order. She left office on 20 May 2024; Lai Ching-te is president. A blackout is not a finding that every reactor was thereby safe. A Pelosi transit is not a PRC missile. Allegation of a stolen 2018 referendum is not stored as a completed steal. An indigenous apology is not a land-title gazette. A New Southbound brand is not an FTA by itself. A 2024 LY split is not a finding that the 2020 mandate was void.
Why it matters
The path is demographic ageing: a completed ultra-low TFR spell raises long-run labour-and-pension pressure even when other welfare instruments improved.

Evidence
The sources behind this fact and its verification state.
- 1.Reuters — Taiwan births stay near record lowsReuters · High credibility · verified
- 2.Department of Household Registration — vital statistics, TFR remaining near world lows, 2023Ministry of the Interior Taiwan · High credibility · verified
What the sources establish
Ministry of the Interior Taiwan carries the official instrument or communique. Reuters records the same dated act independently.
Established: 2023 TFR remaining among the world’s lowest during her presidency, independently reported.
Not established: that she uniquely caused East Asian late marriage, or a unique later pension coefficient from one year.
Households delayed births. MOI measured. Regional patterns predated her.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Taiwan’s fertility rate stays among the world’s lowest on Tsai’s watch, not a later speech about Taiwan’s fertility rate stays among the world’s lowest on Tsai’s watch.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to Her cabinets owned housing, wage, and family-policy instruments. Households delayed births. MOI measured. Regional patterns predated her. That limit is the alternative to treating office-holding as authorship of every later series.
