15,000 and 25,000. About 2,000 of these live in Finland and between 5,000 and 6,000 in Sweden, with the remaining portions being in Norway.

Based on the highest estimates above of 18,000 speakers in Norway, and Statistics Norway estimating the total population of Norway to be 5,594,340 at the start of 2025, this gives the percentage of Northern Sámi speakers in Norway as approximately 0.32%. Similar calculations for Sweden and Finland give them as 0.05% and 0.03% respectively in those countries.
