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.
Since 2013, the number of people across the region identifying as "not religious" has risen from 8% to 13%. The rise is greatest in the under 30s, among whom 18% identify as not religious, according to the research. Only Yemen saw a fall in the category.
