Finland in numbers: population, area, lakes and islands
Finland had 5,652,881 residents at the end of 2025. Statistics Finland's Finland in Figures 2026 lists an area excluding sea waters of 338,493 km² and an estimated 168,000 lakes of at least 500 m². Each figure needs its reference date or definition.
Four basic figures
| Measure | Figure | Date or scope |
|---|---|---|
| Population | 5,652,881 | 31 December 2025, Statistics Finland |
| Area excluding sea waters | 338,493 km² | 1 January 2026 |
| Lakes | About 168,000 | At least 500 m², an estimate |
| Islands | 198,000 | Figure stated by the official Island Policy website |
Sources checked on 11 November 2026. The island figure comes from the Island Committee's website and should not be combined with a size threshold from another source.
Population is not a live counter
An end-of-year population figure describes a particular date. It differs from a later monthly preliminary release. The publication year alone does not establish which date the population represents.
For a school assignment or comparison, retain the label “31 December 2025”. This avoids presenting the number as today's population. Comparisons between countries are clearer when their reference dates match.
Why are different areas quoted?
Land, inland waters and sea waters are separate components. The table's area includes land and inland waters but excludes sea areas. Comparing it with land area alone creates an apparent contradiction.
Check the units and scope before comparing figures. Square kilometres and hectares differ, and a rounded tourism description is not a precise measurement.
How many lakes does Finland have?
“The land of a thousand lakes” is not a literal count. The 2026 Statistics Finland estimate includes lakes of at least 500 m². Changing the threshold changes which water bodies enter the count.
A lake count says nothing about the size of individual lakes or access to their shores. Choosing a destination also requires a map, a route and information about local services.
What about islands?
The official Island Policy website gives a total of 198,000 islands, checked on 11 November 2026. Its headline figure does not state a minimum island size alongside the number, so no threshold is assumed here.
For a visitor, accessibility is often the next useful question. An island may look close on a map while the available transport and landing places determine the practical route.
