More than half of the churches in the southern hemisphere have fewer than 30 members, with one church even reporting that it is down to fewer than two.
This year the church in Australia has been hit hard by the global pandemic, with the church down to less than 10.
This is the result of a new Catholic census, and as the world’s most Catholic country, Ireland has seen a significant number of its churches come under attack by the Catholic Church.
The Irish census report, published on Wednesday, said the number of Catholics in Ireland fell from 28 per cent in 2014 to 21 per cent this year, with a drop in membership from 18 per cent to 17 per cent.
In the United States, which is the second-most Catholic country after the United Kingdom, the number dropped from 21 per the same period to 15 per cent, the report found.
The report said that in the UK, where Catholics account for only 14 per cent of the population, the decline is even more dramatic, with their numbers dropping from 16 per cent at the start of this year to just under 12 per cent now.
The figures also show a significant drop in the number in Australia, with only 14.7 per cent reporting that they were in communion in the latest census.
In Ireland, which has a population of almost 13 million people, the figures were even worse.
They were down from 13.9 per cent last year to 13.5 per cent today.
The latest figures also indicate that there is still a significant amount of work to be done before the end of this century to improve the situation in Ireland.
This includes improving access to healthcare for those who do not have a partner and those who are not married.
The Catholic Church is currently involved in a public relations and development campaign in Ireland, but this will be a long process and will take years, the Vatican said.
