Using a micro-level dataset of over 1 million listings, the housing rental index for Poland from 2000 to 2023 was constructed. The offer data for the biggest cities comes from two different sources. The earlier data were obtained from archival advertisements in photocopies, photographs or periodicals, then digitally reproduced and arranged in a database. The data from 2009 were collected from advertising portals (gratka.pl / otodom.pl)  several times a quarter. The hedonic indices were determined for the city level and then aggregated. This allowed us to investigate the rental market during the financial crisis, COVID-19 or the refugee crisis caused by Russia's invasion of Ukraine.
