Perhaps someone knows a most recent stat on what percentage of Mennonites are considered Conservative Mennonite throughout the world. Here in Ontario Canada they are about 1 out of every 5 Mennonites -
According to a University of Waterloo report, "of the estimated 59,000 Mennonites in Ontario, only about twenty percent are members of conservative groups"
Obtained from here -

The church I attended was a Mennonite Brethren and inquiring on the Internet with 'how many mennonite brethren in ontario canada' question the answer was 37,000. They are considered to be Moderate Mennonites or as some here may put it even 'Worldly Mennonites'
So, if 20% of 59,000 are CMs (approx. 12,000) and MBs make up 37,000 (63%) then this only leaves 10,000 of other kinds of Mennonites in Ontario which about half of these are United Mennonites.
If this holds true that of all Mennonite church members in the world only 20% are considered or consider themselves 'conservative' (which perhaps someone knows where good stats could be found), then just how much special accommodation needs be considered for the 20%.
