Data & methodology · 資料方法
Evidence,
not vibes.
TWNUSA deliberately mixes live data, curated planning models, government-source guides and pure formulas. The important part is telling you which is which.

Rules we keep
Uncertainty stays visible.
A useful model can be approximate. A dangerous model pretends it is precise. TWNUSA keeps estimates labeled, dates visible and source boundaries explicit.
01
Live ≠ real-time
USD/TWD is a daily reference dataset. We never call it an executable bank quote.
02
Model ≠ fact
Cost and city scores are decision aids with inspectable assumptions, not rankings handed down as truth.
03
Official wins
For immigration and other rules, the linked government source outranks our summary.
04
No hidden profile
Calculators run without an account, ad profile or behavioral tracking layer.
