historical development of Christianity in the world and continents from a statistical view, also compared with Islam
Dick Slikker, MSc
I stumbled upon your figure “Figure 5. Statistical development of the percentages of Christian and Muslim populations with respect to the total population of Europe as a whole from 1900 to 2010 (WCD)”. I was wondering what your what your source is. What is WCD? By the way, you might want the change the word “Europian” in the y-axis title to “European”.
WCD is World Christian Database.
OW is Operation World. (see figure 1)
in scientific reports mostly WCD is used.
