The numbers behind the mosque directory

Four countries, side by side

OpenStreetMap data via the Niyat mosque directory, 14 September 2026; counts reflect mapped mosques, not all mosques. Percentages are of each country's listed mosques; the nearest-neighbour figure is the median distance to the closest other mapped mosque in the same country.

Methodology

Source. All figures are computed from data/mosques.json, the OpenStreetMap-derived extract behind the Niyat mosque directory (14 September 2026 build), and the directory index of published pages. OpenStreetMap coverage is partial: many mosques are not yet mapped, mapped mosques may lack tags, and tags can contain errors. Nothing here is a census of mosques; counts reflect mapped mosques, not all mosques.

Which mosques are counted. A directory page exists when a mapped record carries both a name and a city (addr:city). Records missing either are excluded and reported per country. City totals group the addr:city value the same way the directory builds its city pages.

States and regions. United States, Canadian, and Australian tables use the OpenStreetMap addr:state / addr:province tags where present. United Kingdom regions are derived from the postcode area of addr:postcode (for example BD maps to Bradford, in Yorkshire and the Humber) using the standard twelve nations and regions. Coverage of these fields is uneven; each table states how many records it covers.

Facilities and contact. Shares are computed over the country's listed mosques. Website and phone reflect the presence of those tags; wheelchair shows the tag's values (yes, limited, designated, no); women's facilities reflect the small number of female / women tags. An untagged mosque may still have the facility — absence of a tag is not absence of a feature.

Denomination. Shown only where the denomination tag exists; the share of mosques with no tag is listed alongside.

Nearest-neighbour distance. For every mapped mosque, the great-circle (haversine) distance to the closest other mapped mosque in the same country, found with an approximate spatial-grid search in plain Python (no external libraries). The median is taken over mosques with at least one mapped neighbour.

Licence and attribution. The underlying map data is © OpenStreetMap contributors and available under the Open Database Licence (ODbL). If you republish figures, keep the caveat that counts reflect mapped mosques, not all mosques.
