This dataset was originally used to study the recognition rates of mosque-communities in Belgium. Each row represents a unique Belgian mosque, which has been anonymized. For each unit, I include a regional indicator, ethnicity indicator, network indicator, and recognition status indicator. All variables from the original dataset that could potentially be used to de-anonymize a mosque have been excluded, but may be available upon request from the author. The data made available has been sourced from publicly available reports, such as those produced by the Executive for Muslims in Belgium.
