Dataset for matching estimation, based on Social Diagnosis, Statistics Poland and Orliki databases.

To construct the datasaet, firstly, the Social Diagnosis (SD) data was used – a dataset based on results of a representative, longitudinal study conducted by an interdisciplinary board of academics in 2000-2015 [[i]]. Furthermore, the SD dataset has been combined with two datasets on sports infrastructure: The Statistics Poland (SP), conducted every four years, the latest, from 2014, was used for our analysis [[ii]] and the “Orliki” database, containing information on facilities constructed in 2008–2012 within a publicly-funded programme [[iii]]. The data has been combined by calculation indicators of availability: number of sports facilities of particular types per capita, at the NUTS (Classification of Territorial Units for Statistics) 3 level. <br> 1.
