Here’s what I found after checking each claim against official statistics:
London – Mohammed: Mostly true. Muhammad was the most popular boys’ name across London in 2024, topping the list in boroughs like Barking & Dagenham, Croydon, Ealing, Hounslow, Newham, Redbridge, and Waltham Forest.  However, it’s worth noting that Alexander also topped eight boroughs in 2024 , so the picture is more nuanced than the post suggests.
Manchester – Mohammed: True. Muhammad has been Manchester’s top boys’ name for several years. In 2023, it was the most popular boys’ name in eight of Greater Manchester’s ten boroughs. 
Berlin – Mohammed: True for 2024, but now outdated. Muhammad was the most common name given to boys in Berlin in 2024, and has been for the last six years.  However, in 2025, Noah took the top spot for boys in Berlin, and Mohammed dropped to sixth place. 
Brussels – Mohammed: True. Mohamed was by far the most common forename given to newborn boys in Brussels , and since 2008 it has been the most popular baby boy name in Brussels. 
The Hague – Mohammed: False. In Amsterdam and Den Haag, Adam is the top name for boys, while Mohammed is most popular in Rotterdam.  So the post has the wrong Dutch city — it should say Rotterdam, not The Hague.
Amsterdam – Mohammed: Also false. Same source: in Amsterdam, Adam is the top name for boys.  Adam and Olivia are Amsterdam’s most popular baby names in 2025  as well.
Oslo – Mohammed: True. Oslo’s rankings reflect immigration patterns, with Mohammad topping the boys’ list in the capital despite ranking much lower at the national level. 
Warsaw – Jan: Plausible. In 2023, Jan was the most popular boys’ name in Warsaw with 678 baby boys.  I couldn’t find 2024 Warsaw-specific data, but nationally in 2024, Nikodem was the most popular name , and Nikodem wasn’t even among the top boy names in the capital city , so Jan likely remained at or near the top in Warsaw.
In summary: The post gets London, Manchester, Berlin, Brussels, and Oslo roughly right (though Berlin’s data is now outdated). It gets Amsterdam and The Hague wrong — Mohammed is not the top name in either city (Adam is; Mohammed tops Rotterdam instead). Warsaw–Jan appears accurate. The post also doesn’t mention that these are only boys’ names, not all children’s names, which is a meaningful omission.
