Only the 2020–2024 inflow. The cost of previously received individuals is not included. Total net cost including the whole stock is likely 5–15× higher — Ruist's national estimate corresponded to roughly −4,100 SEK/resident/year in 2015 for the entire refugee stock.No vulnerable areas in this municipality according to the Swedish Police situational report 2025.
Marginal cost = (received 2020–2024 / 5) × Ruist's net cost per person and year (74,000 SEK in 2018 prices, inflation-adjusted to 2025; range 53k/74k/94k → 67k/94k/119k) / population. Not official municipal statistics.
