Poland Rental Market Medians
Median asking rents for residential rentals across Poland, by city, district and flat size, measured from live listings. The collection pipeline runs nightly; these downloadable editions are periodic, not automatically refreshed nightly. Use the dated live API for the current serving snapshot.
- Snapshot: 2026-09-13
- Coverage: 49 cities, 96 city districts, 1–4 room flats
- Sum of city-level sample sizes (district rows overlap these): 22,036
- History: monthly series from 2026-06 to 2026-09
- Licence: CC-BY-4.0 — free to use commercially, attribution required
- DOI: 10.5281/zenodo.21892638 — permanent, resolves to the latest archived edition (which may lag the API)

Columns
| Column | Meaning |
|---|---|
city |
City slug (ASCII, e.g. warszawa, lodz). |
district |
District slug, empty for city-wide rows. |
level |
city or district. Lets you filter without knowing the sentinel. |
rooms |
Number of rooms (1–4). Polish listings count rooms, not bedrooms. |
median_pln |
Median monthly asking rent in PLN. |
sigma |
Fitted lognormal dispersion. Higher means a wider local spread. |
n_listings |
Listings behind that median. Treat small n with caution. |
snapshot_date |
Date the snapshot was computed (UTC). |
Method
Listings are scraped nightly from three Polish rental portals (Otodom, OLX, Morizon) across all 16 voivodeships, deduplicated across sources by a two-stage entity resolution (exact source-id, then cross-source fuzzy block-and-score), and aggregated over a 14-day active window. Medians are computed with a lognormal fit and outlier trimming. Districts are used where the sample supports it and otherwise fold into the city aggregate.
These are asking rents, not signed rents. They measure what landlords list,
and signed rents may differ. Fees and flat quality vary across listings. n_listings is published on
every row precisely so you can judge how much weight a given cell carries.
The history is forward-only. Listings disappear when they let, so a month that was not captured cannot be reconstructed afterwards. The monthly series starts when collection started and grows from there.
Correction and provenance
The August 11, 2026 edition contained 528 cells, including 60 district cells whose median, sigma and n exactly matched the old modelled seed. Those values were not verified listing observations. The site emitter removed the seed overlay on September 4; the mirrors missed that correction until this edition. Use editions dated September 13, 2026 or later for measured-only current cells. Older Git/HF/Kaggle versions and archived DOI editions remain historical records; their files are not rewritten. Their current-grid sample counts must not be interpreted as entirely measured. The monthly city-history file is separate.
The current month in history is partial and uses the latest captured snapshot, not a final month-end value. City coverage can change. Sum only city-level samples when counting observations across the current grid: district samples overlap. A provenance manifest records the exact source commit and file SHA-256 digests.
Citation
If you use this downloadable edition, cite its snapshot date and the repository,
and retain provenance.json with the source commit and file hashes. See

The Zenodo concept DOI identifies archived editions, which may lag this download. Only cite a Zenodo version DOI for these files after verifying that its snapshot and file hashes match; an export date is not proof of archival.
