Christians were 46% of the voters in 1994 - 39.5% in 2009 and 36% today. Sunni alone are around 30% of the voters
36% of Lebanese Voters are Christians but Christians represents less than that if we count the 0-21 Y.O who do not vote. Maybe 32-33% and if we add the Palestinians and Syrians living in Lebanon I think Christians are probably and currently something like 19-20% of the people living in Lebanon.
Maybe at the next elections Shia voters alone and Sunni voters alone will outnumber the Christians voters. I doubt then that each of them will accept to get 28 MP while Christians get 64.
The two main Christians parties are acting by ignoring completely the problem. Burying their head in the sand. In the same time even in traditional Christians areas thousands of real estates are being bought every year by non Christians. The face of every so-called Christian district is changing each year.
Lebanon was built on a parity between Christians and Muslims, in a time where both were around 50% of the General population. But now things have changed completely and every few years Christians lose 3-4% of the total Lebanese voters.
Hopefully after these elections Christian parties would raise that issue bluntly. The naturalisation decree from the nineties should be canceled and Lebanon should shift to a federal system similar to the one established in Belgium or Switzerland. This in my opinion is the major and main issue Christians should focus on after the elections. Not electricity, corruption, infrastructure etc. But on a system that will help to avoid the Christians of this country to find themselves in a Few years in the same situation as the Christians of Syria, Irak, Jordan or Egypt due to demographic changes.
Maronite voters from 2009 to 2018 increased by 3% and all Christians by 2.8%, while in the same period of time Shia voters increased by 20% and Muslims by 19%. For the first time maronites fell under 20% of the voters.
The Serbs were 90% of Kosovo after WWII... now they represent 10%
