Efterfrågekartan
Efterfrågekartan is a Swedish AI mapping tool from analysis firm Evidens that turns three years of real apartment sales into a heat map of housing willingness to pay, shown neighbourhood by neighbourhood across a single municipality.
What is Efterfrågekartan?
Efterfrågekartan ("the demand map") is an AI tool from the Stockholm analysis and advisory firm Evidens that answers one question: where, inside a Swedish municipality, are people actually willing to pay for housing? It converts that willingness to pay, what Evidens calls the purchasing-power demand, into a heat map that shows at a glance which areas are the most attractive.
The method is deliberately plain. The tool takes owner-occupied apartment sales genuinely completed over the previous three years, then adjusts each one for size, monthly fees and the date of sale so that every transaction becomes comparable. Historic prices are uplifted to today's level and fees are normalised. Evidens describes the effect with a useful image: it is as if you could move one identical home around the municipality and read off directly what value it would take on in each location. The result is drawn at DeSO level, the official Swedish small-area statistical geography, and it is refreshed every month.
The publisher is unusually open about the limits. It states plainly that the data is not adjusted for number of rooms, year of construction or floor area, and that the purpose is to give an overall and transparent picture of housing demand in Sweden rather than a valuation of any individual property.
The intended use is prioritisation. After several years of rising rates, inflation and construction costs, many Swedish housing projects have been paused and few developers can push every scheme forward at once. Efterfrågekartan is sold as an input to portfolio steering: ranking a land bank, choosing which detailed development plans to pursue, informing comprehensive planning, and understanding land values, which Evidens frames as better control, more negotiating strength and a more accurate planning basis.
It is delivered as a browser application reached with credentials, and it sits alongside four other Evidens digital services: Evidens Online, a housing supply tool, Prissättaren and Prognosmakaren. Its methodological ancestor is the market-depth calculation Evidens developed in 2018 for the Swedish government inquiry SOU 2018:35.
What it does

- Refresh the picture every month so the map tracks the current market
When to use Efterfrågekartan / When not to
A quick filter to help you decide if Efterfrågekartan is the right fit.
When to use Efterfrågekartan
- Housing developers deciding which projects in a stalled pipeline are worth restarting first
- Swedish municipal planners preparing detailed development plans, comprehensive plans and land-value assessments
- Land and project portfolio managers at property companies who need to rank sites objectively
- In-house market analysis teams that want a maintained demand dataset instead of building one
- Property valuers and appraisers looking for location-adjusted evidence of what buyers actually pay
When not to use Efterfrågekartan
- Anyone working outside Sweden: the tool is built on Swedish transactions and Swedish DeSO statistical areas
- Teams focused on rental or commercial property, since the map is built from owner-occupied apartment sales
- Analysts needing unit-level precision, as the data is deliberately not adjusted for room count, build year or floor area
- Developers who want an API or a data feed to push into their own systems, which this product does not offer
- Buyers who need to self-serve, compare tiers online and sign up without speaking to the vendor

Pros & Cons
Pros
- The price is published openly, which is rare in Swedish property analytics
- Unlimited logins are included, so cost does not scale with the size of the team
- The dataset is refreshed monthly rather than annually
- It is built on transactions that actually completed, not on asking prices or listings
- The method and, unusually, its limitations are both stated on the product page
- A free demonstration and a two-week trial period are both offered before committing
- The publisher is an established Swedish market analyst with a public methodological track record
Cons
- Sweden only, and the base price covers a single municipality
- The data is not adjusted for room count, build year or floor area, as the publisher itself states
- Owner-occupied apartments only: neither rental nor commercial property is covered
- No terms of service are published for a product sold at SEK 25,000 per year
- Nothing is published about hosting, data retention, subprocessors or model training
- No API, no documented third-party integration and no mobile application
- There is no self-service trial or checkout; every route runs through a form or an email
- The product page exists only in Swedish, and the site's English version does not describe this tool at all

Data, GDPR & hosting
A consolidated view of how Efterfrågekartan handles your data.
GDPR overview
The words GDPR and dataskyddsförordningen appear nowhere on the site, so no compliance claim is made in writing. What is published is a short privacy policy describing GDPR-shaped rights without naming the regulation: access to stored personal data once a year, correction or erasure at any time, withdrawal of consent at any time, and the right to complain to a supervisory authority. A data controller is reachable at pua@evidensgruppen.se, and the postal contact and company number are given. A cookie banner offers three categories: necessary, statistics and personalised advertising. There is no DPO, no data processing agreement, no subprocessor list and no mention of transfers outside the EU. The publisher is established in Sweden, so no Article 27 representative applies.
Who owns the data?
The site publishes no terms of service, no licence and no customer agreement for this product, so nothing states who owns what once you subscribe. The only legal document is a short privacy policy, and it covers just the contact forms on the website. It names Evidens, Sibyllegatan 32, 114 43 Stockholm, company number 556727-4161, as the controller of that form data, collected on the basis of consent to establish or maintain a business relationship. The underlying map is built from real property transactions rather than from anything a customer uploads, so the practical question is narrow, but it is left unanswered in writing. Ask for a contract before committing.
Reuse rights
No published terms grant or restrict reuse, so a subscriber has nothing in writing telling them what they may do with the output. In practice the product is sold as decision support for portfolio steering, planning and land valuation, and the paid add-on of transaction point data with uplifted and normalised prices is clearly meant to be worked with internally. Evidens does describe an open-source approach to publishing its methods so that others can reproduce them on their own data, but that statement concerns its published research methodology, not a licence over this tool's data. Redistribution rights, internal-use limits and client reporting rights all need to be agreed contractually.
Data retention & training
Hosting summary
No hosting jurisdiction, country or region is declared anywhere on the site, and there is no trust or security page. The only first-party technical signal is the address of the application itself, which is served from a Microsoft Azure App Service domain and presents a Streamlit front end; the Azure region is not stated, so no country can be inferred. The marketing website is a separate matter: it resolves to a Swedish host in Gothenburg, which says nothing about where the product or its data actually run. No subprocessors are listed, no transfers outside the EU are mentioned and no standard contractual clauses are referenced. The publisher is established in Sweden, so EU law applies to it, but that is a fact about the company rather than a published commitment about the infrastructure. Anyone with a data residency requirement should treat hosting as an open question and get it answered contractually before subscribing.

Things to keep in mind
Risks and trade-offs to weigh before adopting Efterfrågekartan.
- A clean heat map reads like a forecast, but it summarises three years of past sales and predicts nothing on its own
- Two areas of the same colour do not hold the same home: the data ignores room count, build year and floor area
- High-stakes land and planning decisions can end up resting on one vendor's single dataset
- Mapping willingness to pay onto real neighbourhoods invites territorial stigmatisation and social displacement effects
- Nothing is published contractually: no terms, no processing agreement, no availability or exit commitments
- Nothing is published about hosting location, retention or whether customer activity feeds model training
- The AI label is claimed for this product without any published detail of the models or features behind it
Setup & Integrations
Technical difficulty
There is nothing to install and nothing to configure. Efterfrågekartan is a browser application: once the subscription is agreed and credentials arrive, you sign in and read the map. There are no connectors, no API and no technical parameters to set. The real friction is commercial rather than technical, since access runs through a contact form or an email and the covered municipality is chosen at subscription. Expect Swedish as the working language of the product and its documentation.

Should you pick Efterfrågekartan?
Efterfrågekartan is a narrow tool that knows exactly what it is. One country, one property type, one question: where inside this municipality are buyers willing to pay, and by how much. Within those bounds it is well made. The data comes from sales that actually completed, the normalisation for size, fees and date is explained rather than hidden, the map is refreshed monthly, and the publisher volunteers the fact that its figures ignore room count, build year and floor area. That last admission is worth more than most vendor claims, because it tells you precisely how far the map can be pushed.
The pricing is equally refreshing: a published SEK 25,000 per year, with unlimited logins, in a market where most competitors say nothing at all. The limit is that it buys one municipality, so a developer active across a region will be negotiating extensions with no public reference point.
What is missing is the contractual and technical half of the product. There are no terms of service, no data processing agreement, no statement of where the application is hosted, no retention rules and nothing on whether models are trained on anything a customer touches. For a browser tool feeding long-horizon land and planning decisions, that is a real gap, and one to close in writing before signing. Access is also entirely mediated: no self-service trial, no online checkout, a Swedish-only product page, and an English site that does not mention this tool. Treat the free demonstration and the two-week trial as the moment to ask the unanswered questions.
