Why the outline matters
The narrow central section links northern and southern regions across a long distance, so area alone understates geographic reach.
A fitted country map can hide that difference unless Taiwan and Vietnam share one scale.

Place guide
How should this Vietnam profile be read?
Vietnam is a long coastal country with more than one hundred million residents. Its area and average population are drawn from the official 2024 statistical summary.
Population reference
The current source uses average population during 2024 rather than a year-end register.
That definition stays on every comparison so precise ratios are not separated from their statistical basis.
