Data and methodology
VienāVietā is a search engine that brings together car and real estate listings from several Latvian and Lithuanian portals. This page explains where the data comes from and how we calculate the figures shown on our pages, the price map and the monthly market reports.
Data sources
Number of active listings by source right now. We also use State Land Service data on apartment transactions (data.gov.lv, licence CC BY 4.0), which show actual transaction prices.

What we take from other portals
Only facts: make, model, year, price, area, number of rooms, location, a link to the original listing and the thumbnail address. We do not take sellers' descriptions or contact details, and we do not store photos. Titles are generated by us from the facts.
The newest listings are checked several times an hour, and a full check of each portal runs once a day. A listing that can no longer be found on the original portal is removed from our site.
Duplicates
The same car or apartment is often listed on several portals. We group such listings by their facts (make, model, year, mileage or address, area, price). The list shows one card with links to all portals, and the object is counted once in the statistics.
Median
Price summaries show the median, not the arithmetic mean: half of the listings are cheaper than the median and half are more expensive. The median is not distorted by a few very expensive or mistaken listings. Listings without a price or with a price of 0 are not counted.
Price per square metre
The price per square metre is the listing price divided by the area; only listings with an area above 10 m² are counted. For rentals it is the monthly rent per square metre.
On the price map a place (a Riga neighbourhood, town or parish) is shown only if it has at least 5 active listings. The colour steps are quintiles: each step contains roughly one fifth of the places.
Price drops
We record each listing's price when we first see it and after every change. A "price drop" means the current price is lower than the starting price; "in the last 30 days" means the price changed within that period. The percentage is calculated from the starting price.
Limitations
Listing prices are asking prices, not transaction prices. Actual apartment transaction prices come from State Land Service data, which is published with a delay of a few months.
For vehicles the location is usually known only at the town or municipality level. Pages with fewer than 3 listings are not shown to search engines, as such small numbers say little.
The monthly report counts all listings available during that month; while the month is in progress the figures change every day.
Citing
You may quote the figures if you name the source "VienāVietā (vienavieta.lv)" and the date, as the data changes daily. Questions about the data: info@vienavieta.lv.
