since virtually all of these 23 western and smaller eastern rites are in union with the Pope , there is
actually one Catholic Church, not 242 churches or denominations. Based on the encyclopedia's own definition of "denomination"
the editors appear to be separating and counting by country which is how you get to 242 (or 238 countries plus 4) "denominations" of Roman Catholics.
The Catholic Church in Canada is
not a different "denomination" from the Catholic Church in the U.S., which is
not a different Catholic Church from the one in England, etc. If you search the available "World Christian Database" online, there is indeed one Catholic Church in the U.S.A., (see also Barrett, Encyclopedia, volume 1, page 783 for the U.S.A.) and in the world there are indeed 238 "Roman Catholic" denominations (for exactly 238 countries), i.e. one Catholic Church for each country. The same "counting by country" seems to be the case with some of the denominations in the other mega-blocs.
When dividing these "denominations" by country as they do, there are definitely some problems in figuring out the true total "denominations" since many of them are being counted more than once -- and in fact 241 times too much in the case of "Roman Catholic" denominations.
Barrett's Encyclopedia states this explicitly:
“As a statistical unit in this Encyclopedia, a 'denomination' always refers to one single country. Thus the Roman Catholic Church, although a single organization, is described here as consisting of 236 denominations in the world's 238 countries.” (Barrett, et al, World Christian Encyclopedia, volume 1, page 27, in the "Glossary" under definition for "Denomination" [later updated to 242], emphasis added)
How dishonest...
