The default listing of WRD cities now consists of the UN's 1,785 Urban Agglomerations each with over 300,000 population in 2015. The percentage of the majority religion and a listing of religions over 1 percent are shown for capital cities and every city over 1 million. An archive of 8,537 cities (level 1) and sub-cities (level 2) in 2010 down to 50,000 population is also available.

Roman Catholicism is one of the four major traditions of Christianity (together with the Orthodox, Protestant, and Independent traditions). The number of people affiliated with the Roman Catholic church in 2015 has been updated in each country to align with the 2016 edition of the Vatican’s Catholic Church Directory (Annuario Pontificio). The 2015 data for each major tradition will progressively change from projections to hard data as reports, year books and censuses covering 2015 become available.
