The number of permanent deacons is showing "strong expansion" globally, but especially in Europe and the Americas, it said.
At the end of 2011, the worldwide Catholic population reached 1.214 billion, an increase of 18 million or 1.5 percent, slightly outpacing the global population growth rate, which was estimated at 1.23 percent, said a statement published May 13 by the Vatican press office.
Catholics as a percentage of the global population remained "essentially unchanged" at around 17.5 percent, it said.
The statement reported a handful of the statistics contained in the Statistical Yearbook of the Church, which reported worldwide church figures as of Dec. 31, 2011.
Officials of the Vatican Secretariat of State and its Central Office of Church Statistics presented the first copy of the yearbook to Pope Francis during an audience May 13; they also gave him the first copy of the 2013 "Annuario Pontificio," a volume containing information about every Vatican office, as well as every diocese and religious order in the world.
According to the statistical yearbook, the increase in the number of Catholics in Africa (4.3 percent) and Asia (2 percent) greatly outpaced their regions' population growth, which was 2.3 percent and 1.2 percent, respectively.
The growth of the Catholic community in Europe and the Americas was even with regional population growth, which was about 0.3 percent for both, the yearbook said.
At the end of 2011, most of the world's Catholics (48.8 percent) were living in the Americas, followed by Europe with 23.5 percent, Africa with 16 percent, 10.9 percent in Asia and 0.8 percent in Oceania.
The Vatican said the number of bishops in the world increased from 5,104 to 5,132.
The total number of priests -- diocesan and religious order -- around the world grew from 412,236 to 413,418, increasing everywhere except the Americas where numbers stayed mostly the same, and Europe, where the number of priests has gone down more than 9 percent over the past decade.
The number of permanent deacons reported -- about 41,000 -- was an increase of more than 1,400 over the previous year and a 40 percent increase over the past decade. The vast majority -- 97.4 percent -- of the world's permanent deacons live in the Americas or in Europe.
The number of men joining a religious order showed substantial growth over the past decade in both Asia (up 44.9 percent since 2001) and Africa (up 18.5 percent since 2001); in contrast their numbers fell in Oceania by 21.9 percent over the past 10 years, in Europe by 18 percent and in the Americas by 3.6 percent over the past decade.
The number of women in religious orders has shown "a sharp downward trend" with a 10 percent decrease in the numbers of women religious worldwide since 2001, it said. The increases in Africa and Asia weren't enough to offset the reductions seen in Europe, the Americas and Oceania, it said. Catholic women's orders went from having a total of more than 792,000 members in 2001 to just over 713,000 women at the end of 2011.
The number of candidates for the priesthood -- both diocesan seminarians and members of religious orders -- showed continued growth worldwide, rising from 118,990 at the end of 2010 to 120,616 at the end of 2011.
In the past 10 years, it said, the number of men preparing for the priesthood rose more than 30.9 percent in Africa and 29.4 percent in Asia. Numbers decreased in other regions of the world, particularly Europe, which saw a 21.7 percent drop in priesthood candidates between 2001 and 2011.
