The comedian Vic Reeves once remarked that “88.2 per cent of statistics are made up on the spot”. That might not be too far off the mark when it comes to Catholicism. The Church rightly prioritises the salvation of souls over the gathering of statistics. Nevertheless, the Vatican does release an annual compendium of figures that offers some insight into changes in the worldwide Church. Known as the Annuarium Statisticum Ecclesiae, it is compiled by the Central Office of Church Statistics in Rome. The 2019 edition, published last week, presents the figures for 2017 – the most recent year available.
