Not really. Considering the following statistics in 2007:
Vatican, Feb. 12, 2007 (
CWNews.com) - The
world’s Catholic population grew by 17 million in 2005– the last year for which full statistics are available-- according to the annual Vatican yearbook, the Annuario Pontificio.
Despite an increase from 1.098 billion to 1.115 billion,
the Catholic proportion of the world’s population remained virtually, because the Catholic population grew at a rate (1.5%) barely above the overall population growth rate (1.2%).
Cardinal Tarciscio Bertone, the Vatican Secretary of State, formally presented the first copy of this year’s Annuario Pontificio to Pope Benedict XVI (bio - news) at a private audience on February 12. Cardinal Bertone was accompanied to the audience by Archbishop Leonardo Sandri, the deputy Secretary of State, whose office is responsible for the annual compilation of statistics.
During the year covered by the latest volume, 2004-2005, the Catholic population grew most rapidly in Africa, at 3.1%, while overall population growth in Africa was 2.1%. The Catholic population also grew faster than the overall population in Asia (2.7% to 1.2%) and the Americas (1.2% to 0.9%). (The Vatican treats North and South America as a single continent for statistical purposes.) In Europe the Catholic population increased only slightly, but general population growth was almost flat.
The number of Catholic priests in the world grew slightly over the same year, from 405,891 to 406,411, or 0.13%. That growth was uneven, with increases in Africa (3.8%) and Asia (3.5%) nearly offset by declines in Europe (0.5%), the Americas (0.5%), and Oceania (1.8%). Similarly, seminary enrollment rose in Africa and Asia but fell in Europe and Oceania, with the Americas holding steady.
There were 12 new episcopal sees created during the year, and 9 metropolitan sees. Altogether there were 180 new bishops appointed in the course of the year.
For every Catholic who leaves, thousands more join the Catholic Church from Protestant Churches. There is no decline in Catholic population.
