Totalkostnad för invandringen — sammanställning över metoder

What does the data show?

Objective observations — not interpretations

• No Swedish public authority publishes an official 'total cost of immigration'. Existing estimates are research reports (Ruist/ESO, KI, Aldén & Hammarstedt) with different populations, base years and time horizons.
• The differences between Ruist's cross-section (2015) and KI's generational calculation (2022/2024) stem mainly from method choices: time horizon (one year vs. life-cycle), how public expenditure is allocated per person, and assumptions about future employment, interest rates and transfers.
• Both Ruist and KI show that the employment rate is by far the single most important variable. A one-percentage-point higher employment rate in a group of 100,000 people shifts the public net by roughly SEK 300–500 million per year (rule-of-thumb using KI parameters).
• Aggregated averages hide large differences by grounds for residence: labour migrants, EEA nationals and students are positive net contributors; asylum and family reunification are negative during establishment and converge more slowly.
• The models cover public finances only — taxes, transfers and public consumption. They do not capture macro-economic effects (productivity, innovation, prices, crime costs, cohesion). Positive and negative externalities fall outside the calculation.

Definitions

How the numbers are counted — and what they do not cover

Public net cost

The difference between the taxes and contributions an individual (or group) pays and the public expenditure (transfers plus per-capita-allocated public consumption) the same individual triggers. A negative value = the group is a net recipient of public funds.Covers the public sector only. Private consumption, savings and market-price effects fall outside.

Public revenue

Taxes, social contributions and other payments from the individual to the state, regions and municipalities. Includes direct tax (income tax), indirect tax (VAT, excise duties) and employer contributions.

Transfer

Cash payment from the public sector to the individual without direct counter-performance: child allowance, social assistance, sickness benefit, unemployment insurance, housing allowance, establishment benefit, etc. Counted as public expenditure in the net calculation.

Public consumption

The value of welfare services consumed by the individual: healthcare, schooling, elderly care, justice system. Allocated per person using a distribution key (typically age and sex profiles), not by individual actual use.The allocation method drives a large part of the difference between Ruist and KI.

Public investment

Expenditure on long-lived assets (roads, housing, infrastructure). Usually not included in per-person net contribution because the benefit is spread over many years — but population growth affects the need.

Life-cycle calculation (generational perspective)

Sum of the individual's future taxes minus expenditure across the whole lifetime, discounted to present value. Captures that a 30-year-old contributes for many years while a 70-year-old mainly generates expenditure. KI Special Study 117 and Ruist ESO 2018:3 both use life-cycle perspectives.Requires assumptions about future employment, transfer levels and discount rate.

Cross-section calculation

A snapshot of a single year: how much did the group pay in taxes and how much did it cost that same year? Simple to compute but mixes children, workers and pensioners and depends strongly on age composition.

Fiscal effect

The economist's term for the net effect on public finances. Positive fiscal effect = the group contributes more than it costs the public sector; negative = the reverse. Distinguished from macro-economic effect.

Marginal vs. average cost

Marginal cost = what one additional individual costs given the existing structure (often lower than the average — empty seats in the classroom, spare hospital bed). Average cost = total expenditure divided by number of people. Ruist and KI use averages, which overstates cost at small volumes and understates at large ones.

Opportunity cost

The value of the best alternative not chosen. Rarely explicit in public-finance analyses — but always implicit: a krona to A is a krona that cannot go to B.

Discounting

Converting future amounts to present value using a discount rate. A high rate makes future costs smaller; a low rate makes them larger. KI 2022 used 3 %; falling real rates 2020–2024 raise the present value of long-term costs.

Sustainability calculation

Long-term projection of how public finances handle demography, labour supply and tax revenues over 30–75 years. The Fiscal Policy Council and the EU Commission's Ageing Report use sustainability indicators (S1, S2). Migration is one of several parameters.

Foreign background (SCB)

Foreign-born OR native-born with two foreign-born parents. About 27 % of the population in 2024. A broader German/Dutch definition (including one foreign-born parent) would give a higher share.

Net contribution

Synonym of public net cost but with the opposite sign: a positive net contribution = the group contributes more than it costs. Used in KI's and Ruist's reports.
