You have a good heart.

Let’s see if it was just a typo…
Eric Svendsen “derives” the number from his poorly constructed argument…
ntrmin.org/30000denominations.htm
First, Barrett, writing in 1982, does indeed cite a figure of 20,780 denominations in 1980, and projects that there would be as many as 22,190 denominations by 1985. This represents an increase of approximately 270 new denominations each year (Barrett, 17). …
Barrett identifies seven major ecclesiastical “blocs” under which these 22,190 distinct denominations fall (Barrett, 14-15): (1) Roman Catholicism, which accounts for 223 denominations; (2) Protestant, which accounts for 8,196 denominations; (3) Orthodox, which accounts for 580 denominations; (4) Non-White Indigenous, which accounts for 10,956 denominations; (5) Anglican, which accounts for 240 denominations; (6) Marginal Protestant, which includes Jehovah’s Witnesses, Mormons, New Age groups, and all cults (Barrett, 14), and which accounts for 1,490 denominations; and (7) Catholic (Non-Roman), which accounts for 504 denominations.
…the typical Roman Catholic projection of an annual increase in this number is simply not a given. …
No doubt the same Roman Catholic apologists who so gleefully cite the erroneous 25,000-denominations figure…would reel at the notion that there might actually be 223 distinct denominations within Roman Catholicism!
MY NOTE: I don’t, given that he clearly explains this definition in his Encyclopedia]…
… Barrett indicates in the case of Roman Catholicism that even this number can be broken down further to produce 2,942 separate “denominations”—and that was only in 1970!
Svendsen does not cite the page reference where Barrett “indicates” this, and it appears the OP simply lifted Svendsen’s assertion uncritically, attributing it to Barrett. Given what Barrett clearly states in his 2nd edition, I doubt very much Barrett indicated any such thing in his first edition. However, I still await the page reference from the first edition where Barrett “indicates” what Svenson claims he “inidicates.”
Svendsen continues…
If we were to use the Roman Catholic apologist’s method to “project” a figure for the current day, we could no doubt postulate a number upwards of 8,000 Roman Catholic denominations today!
Unfortunately, the 2nd edition of Barrett’s Encyclopedia does not support Svendsens agument. Svendsen presumed that the increase in total Christian denominations was attributable to Roman Catholic denominations just as much as it was to Protestant denominations. He was wrong, according to the 2nd edition of this
Encyclopedia, which must have been rather embarrassing for him.
Instead Barrett’s
Encyclopedia does indeed describe an increase of Roman Catholic denominations since 1970 as follows…
Roman Catholic denominations:
1970: 238
1995: 240
2000: 242
Yet, the total number of Christian denominations increased as follows:
1970: 16,075
1995: 33,090
2000: 33,909
As stated, this HUGE increase in denominations comes from the shrinking of the number of adherents of “Protestant” and “Anglican” megabloc denominations, and the creation of tens of thousands of “Independent” or non-denominational denominations who still profess distinctively PROTESTANT doctrines.
From the 2001
World Christian Encyclopedia, 2nd ed., by Barrett, Kurian, Johnson, Vol. 1, page. 27:
denomination: any agency consisting of a number of congregations or churches voluntarily aligning themselves with it.
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.**Given the above definition, I agree with Barrett’s numbers regarding 242 Roman Catholic denominations (in a single organization).
Yet, for anyone who actually bothers to look at Barrett’s text, it is
clear that the
explosion in denominations described by Barrett’s
Encyclopedia [16,075 in 1970, 33,909 in 2000; *11+ new denomination per week] is caused by huge increases in those “Independent” denominations who profess distinctively Protestant doctrines, while the Roman Catholic Church is still described as a single organization, consisting in 242 denominations in the worlds 238 counties.
