—The purpose of this manuscript is to present a
reliable estimate of the Muslim population and its percentage
in each country in Oceania from 1950 till 2020. This data is
summarized to be a reference for other studies and discussions
related to the Muslim population. The presented data show
that the percentage of World Muslim population with respect
to the total World population has increased steadily from 17%
in 1950 to 26% by 2020. While the total Oceania population
increased from 13 million in 1950 to 41 million by 2020, the
percentage of Muslims in Oceania increased from 0.2% in 1950
to 1.3% by 2020.
