Here is a brief explanation of the research methodology:

• Data was downloaded from two sources: the UK Companies House https://download.companieshouse.gov.uk/ for companies, and the Register of Charities of the Charity Commission for England and Wales https://register-of-charities.charitycommission.gov.uk/en/register/full-register-download for charities. Both are public data platforms. The registers contain data (including public name, ID, short description, address, dates of registration and dissolution) of companies and charities registered in the United Kingdom. The registers are maintained and updated on a regular basis and are reliable and official source of information.
• Islamic organizations were identified as those containing a one or more keywords in the name. According to CSPII methodology, we used the following English keywords: "islam", "islamic", "muslim", "mosque", "masjid", "halal", "waqf", "awaqf".
• The generated list was verified by a CSPII expert to ensure that non-Islamic organizations were not listed.
• The bubble maps depict the number of Islamic organizations in the United Kingdom in different years.
