Arabs are increasingly saying they are no longer religious, according to the largest and most in-depth survey undertaken of the Middle East and North Africa.
The finding is one of a number on how Arabs feel about a wide range of issues, from women's rights and migration to security and sexuality.
More than 25,000 people were interviewed for the survey - for BBC News Arabic by the Arab Barometer research network - across 10 countries and the Palestinian territories between late 2018 and spring 2019. Here are some of the results.
Acceptance of homosexuality varies but is low or extremely low across the region. In Lebanon, despite having a reputation for being more socially liberal than its neighbours, the figure is 6%.
An honour killing is one in which relatives kill a family member, typically a woman, for allegedly bringing dishonour onto the family.
The survey was carried out by the research network, Arab Barometer. The project interviewed 25,407 people face-to-face in 10 countries and the Palestinian territories. The Arab Barometer is a research network based at Princeton University. They have been conducting surveys like this since 2006. The 45-minute, largely tablet-based interviews were conducted by researchers with participants in private spaces.
It is of Arab world opinion, so does not include Iran or Israel, though it does include the Palestinian territories. Most countries in the region are included but several Gulf governments refused full and fair access to the survey. The Kuwait results came in too late to include in the BBC Arabic coverage. Syria could not be included due to the difficulty of access.
For legal and cultural reasons some countries asked to drop some questions. These exclusions are taken into account when expressing the results, with limitations clearly outlined.
